[{"content":" Alumina ceramic heaters from SINOMAS combine the inertness and dielectric strength of high-purity Al₂O₃ with two complementary manufacturing technologies — surface-printed thick film and fully co-sintered MCH — to cover applications from 3D printer beds and coffee machines to medical instruments, automotive sensors, and inline fluid heating up to 1000 °C. Two types of Alumina ceramic heaters are available at SINOMAS based on different manufacturing technologies. Both are built on high-purity Al₂O₃ ceramic. The difference is in how the heating circuit is integrated — surface-printed or fully embedded. Each approach has a distinct performance profile suited to different OEM design requirements.\nThick Film Heater on Alumina Substrate # A resistive circuit is screen-printed onto a pre-fired alumina substrate and protected by a glass overglaze layer. The result is an extremely flat, high-watt-density heater that can be customized to any planar geometry.\nKey advantages # Ultra-fast thermal response. High watt density and low thermal mass enables ramp rates up to 150 °C/s, making thick film heaters on Alumina substrate the preferred choice wherever instant heat-up is critical.\nPrecision watt distribution. The resistor pattern is individually optimized per heating zone rather than uniform across the surface. More heat where needed, less where it is not — without additional components.\nEnvironment friendly. Low thermal mass and minimal residual heat after power-off. Fully RoHS compliant, free of toxic substances and heavy metal ions.\nWide voltage range. From 5V DC (battery-powered applications) up to 480V AC, with three-phase configurations available on request.\nTypical applications # Medical devices · Analytical instruments · 3D printer heated beds · Packaging and sealing machinery · Semiconductor process heating · Inline fluid and gas heating\nCo-fired Metal Ceramic Heater (MCH) # Tungsten paste is printed onto alumina green tape, laminated, and co-sintered at approximately 1600 °C in a reducing atmosphere. The heating element is fully encapsulated inside the ceramic body — no surface exposure, no oxidation risk, significantly higher dielectric strength.\nKey advantages # Fully embedded heating circuit. The tungsten resistor is sealed inside the ceramic body after co-sintering. No surface exposure means no oxidation, no delamination risk, and no contamination of the heated media (fluid or gas) in contact with the heater surface.\nSuperior dielectric strength. Withstands 4500VAC for a minute in standard testing. The ceramic body itself is the insulator — not a glass overcoat — making MCH the preferred choice for medical equipment, high-voltage OEM assemblies, and applications with strict leakage current requirements.\nRod, tube, needle, and cartridge form factors. MCH can be produced as cylindrical rods from 2 mm diameter, hollow tubes, ultra-thin needles for insertion heating, and press-fit cartridges — geometries that are not achievable with flat-substrate thick film technology.\nExcellent thermal cycle durability. The monolithic structure has demonstrated excellent durability in repeated thermal cycling tests, with performance depending on operating conditions and test methods.\nRoHS and REACH compliant. Tungsten is the resistive conductor — no lead, cadmium, mercury, or hexavalent chromium. Fully compliant with EU environmental directives.\nTypical applications # Coffee machines 3D printer hot ends Dental equipment Soldering tools Medical probes Gas sensor heating (oxygen sensors, NOx sensors, exhaust gas analyzers) Performance Comparison # Parameter Ceramic Thick film MCH Max operating temperature 500 °C 800 °C (limited by lead wire) Peak watt density up to 50 W/cm² (immersion) 80–100 W/cm³ Thermal response up to 150 °C/s \u0026lt; 30 s to operating temp. Dielectric withstand 1500 V AC, 1 min 4500 V AC, 1 min Max voltage 480 V AC/DC, 3-phase Up to 240 V typical Integrated RTD sensor Yes Optional (design dependent) Form factors Flat, ring, tube, custom profile Rod, tube, needle, cartridge Circuit protection Glass dielectric overcoat Fully embedded in ceramic Thermal cycle durability Good Excellent (monolithic) RoHS / REACH Yes Yes — lead-free tungsten Neither technology is universally superior. The right choice depends on geometry, voltage, watt density, and integration requirements.\nWhich Technology Fits Your Design? # Choose thick film when: # Your assembly requires a flat or custom-profile substrate You need integrated on-board temperature sensing Operating voltage exceeds 220 V, or three-phase supply is required Maximum watt density is the primary design constraint Fastest possible thermal response is critical (inline fluid heating, on-demand heating) Choose MCH when: # Your assembly requires a cylindrical form factor — rod, tube, needle, or cartridge Dielectric strength and leakage current isolation are critical (medical, high-voltage OEM) The heater will undergo aggressive thermal cycling Compact diameter integration is required (from 2 mm rod) Chemical resistance and electrical insulation are important.

Lithium-ion chemistry — the dominant technology across electric vehicles, stationary energy storage, telecom backup power and portable industrial equipment — suffers a sharp drop in deliverable capacity and charge acceptance as temperatures fall below 10 °C. For OEM designers working on systems that must operate reliably in winters, cold chain logistics, or outdoor installations, a dedicated battery heater is not optional — it is a fundamental part of the thermal management architecture.\nWhy batteries need heating # The internal resistance of a lithium-ion cell rises steeply below 0 °C. Higher resistance means more voltage drop under load, reduced peak power, and a lower safe charge current. Most BMS implementations reduce charge current proportionally below 10 °C and block charging entirely below −10 °C or −20 °C depending on cell chemistry, to prevent lithium plating and irreversible cell damage.\nThe practical consequences for system designers:\nRange reduction in EV and e-mobility applications, particularly at highway speed where peak power draw is highest Longer charge time or charge unavailability in cold overnight conditions Reduced cycle life if repeated low-temperature partial charges cause uneven lithium deposition State-of-charge estimation errors, because open-circuit voltage curves shift at low temperature Heating the pack to a minimum operating window — typically 5–15 °C for discharge, 10–25 °C for charging — before or during operation eliminates these effects.\nHeater technologies for battery applications # Three heating technologies are available at SINOMAS for battery heating. Each has distinct characteristics that make it the preferred choice for specific battery configurations and operating environments.\nSilicone rubber heaters # Silicone rubber heaters are the most widely used battery heater technology for automotive and energy storage applications due to its balance of flexibility, durability, and cost.\nTypical battery applications: Prismatic module base plates, cylindrical cell module wrap-around, battery cabinet floor heating.\nKey characteristics:\nOperating temperature: −60 °C to +200 °C Thickness: 1.0–2.0 mm (excluding optional aluminium backplate) Power density: up to 3.0 W/cm² (with aluminum backplate) Moisture resistance: IP65 (IP67 is possible upon request) Mechanical flexibility: bendable to tight radii; robust against vibration and mechanical shock per automotive requirements Pressure-sensitive adhesive (PSA) backing available for direct bonding to aluminum housing or cell module walls Polyimide (Kapton®) heaters # Polyimide heaters are the preferred technology when installation space is the primary constraint, and where the moderate maximum power density is compatible with the thermal load.\nTypical battery applications: 18650 and 21700 cylindrical cell packs, pouch cell stack interfaces, space-constrained portable and UPS battery packs.\nKey characteristics:\nOperating temperature: −50 °C to +260 °C Thickness: typically 0.15–0.30 mm Power density: up to 3.0 W/cm² Dielectric strength: excellent; foil element is fully encapsulated Weight: extremely low; suited to applications where added mass is constrained Thick film heaters # Thick film heaters are specified when rapid heating of large thermal mass is required, or where the battery enclosure is a structural aluminium component that can serve as the heater substrate.\nTypical battery applications: High-power battery pre-heating in commercial vehicle and bus EV platforms, aluminium battery tray integrated heaters, applications requiring rapid warm-up from deep cold, industrial battery systems with demanding duty cycles.\nKey characteristics:\nOperating temperature: up to +300 °C substrate surface temperature Power density: typically 5–15 W/cm² — the highest among the three technologies Substrate options: stainless steel, alumina ceramic Profile: 1.5~3.0 mm, the substrate itself determines overall thickness Thermal contact: direct bonding to metal substrate gives very low contact resistance, fast thermal response Custom topology: resistive track routing determines heat distribution — uniform or zoned patterns available Application examples # Electric vehicle traction packs — Silicone rubber or polyimide heaters bonded to the base plate or side walls of lithium-ion module housings. The heater is activated by the BMS when pack temperature drops below threshold during parking or pre-conditioning.\nStationary energy storage (ESS) — Grid-scale battery cabinets operating outdoors in cold climates require continuous low-power heating during winter standby. Silicone rubber heaters mounted to cabinet floor or cell rack structure, controlled by a dedicated temperature controller with NTC feedback. Thermal cutoffs provide secondary over-temperature protection.\nCommercial vehicle and bus EV platforms — High-power thick film heaters mounted to aluminium battery tray provide rapid pre-heating from -30 °C cold start. Large thermal mass requires higher watt density than silicone rubber can economically provide.\nPortable, telecom and backup power — Silicone rubber or polyimide heaters bonded directly to 18650 or LFP cell arrays in UPS systems, telecom backup batteries, portable instrument packs and mobile energy storage devices. Their thin profile and low added mass preserve valuable space and weight budget.\nRequesting a quotation # To specify a battery heater, the following information is required:\nHeater geometry — overall dimensions, any required cutouts, bend radius if the heater must conform to a curved surface Supply voltage and available power — DC bus voltage or AC mains voltage; maximum heater power in watts Operating temperature range — minimum ambient, maximum allowable heater surface temperature Sensor requirements — NTC, Pt100/Pt1000, thermal cutoff, or none Quantity — prototype / NPI quantities and anticipated annual volume Certification requirements — UL, CE marking, REACH / RoHS Request a quotation ","externalUrl":null,"permalink":"/battery-heater/","section":"Customized Heating Solution","summary":"","title":"Battery Heaters for EV, ESS and Industrial Batteries","type":"page"},{"content":"","externalUrl":null,"permalink":"/categories/","section":"Categories","summary":"","title":"Categories","type":"categories"},{"content":"Sino Material Technologies Limited\nC201 Builiding 3, 500 Jianyun Road\nShanghai 201318\nChina\nTel: +86 21 58095179\nEmail: inquiry@sinomas.com\nFlex Heat GmbH\nKantstraße 38\n40667 Meerbusch\nGermany\nTel: +49 152 0393 0593\nEmail: qsun@sinomas.com\n","externalUrl":null,"permalink":"/contact/","section":"Customized Heating Solution","summary":"","title":"Contact","type":"page"},{"content":"SINOMAS is proud of being a quality flexible heating solution provider for occasions when creative heating solutions are needed.\nOur team comprises a broad spectrum of creative professionals working in concert to deliver the most appropriate technical heating solutions.

Flexible refers not only to the physical feature of the heating elements, but also to the convenience for custom development to fit specific demands. Resistive Foil Circuit - the Core of Flexible Heaters # In contrast to heating wires used in high power tubular heaters, etched foil circuits are used in most flexible heating elements. The etched foils have exceptional heat transfer due to their large flat contact surface. With the same design flexibility as flexible printed circuits (FPC), either even heat distribution or multiple heating zones can be achieved.\nResistive foil circuits can be produced by chemical etching or laser patterning, the latter being particularly useful for rapid prototyping or large-size heaters.

Phlogopite mica is an inorganic insulating material with excellent dielectric strength and high temperature capability. Infused with a high-temperature resistant binder, mica heaters can be formed into shape during manufacture and heat-cured to set rigidity. The result is a thin, semi-rigid heating element that delivers high watt density and even heat distribution — suitable for both conduction and radiant heating.\nRequest a Quote Why Choose Mica Heaters # Mica heaters share the etched foil technology of flexible heaters but use inorganic mica insulation instead of polymer films. This makes them semi-rigid rather than flexible, but extends their operating range far beyond what organic insulation can withstand. Mica heaters stand out in two areas that matter most for high-temperature industrial applications.\nThe highest operating temperature among flat heaters. With a maximum operating temperature of 500°C, mica heaters far exceed the limits of silicone rubber (200°C) and polyimide (260°C). This makes mica the natural choice for injection molding barrels, industrial ovens, and semiconductor process equipment where sustained high-temperature performance is required.\nHigh watt density in a compact flat format. Mica heaters support watt densities up to 10 W/cm² — significantly higher than silicone rubber heaters (≤3 W/cm² with heat sink). Combined with a thickness of just 0.5–1.0mm, mica heaters can replace traditional tubular or cartridge heating elements in applications where installation space is limited, without sacrificing power output.\nThe result is a heating element engineered for demanding industrial environments — where temperature range, watt density, and reliable dielectric performance are non-negotiable.\nPhysical Construction / Manufacturing # Mica heaters use a thin etched nickel-chromium (NiCr) alloy foil as the resistive element. The resistance pattern is designed in CAD and transferred to the foil, which is then processed through acid spray etching to produce the desired circuit geometry.\nThe etched foil element is sandwiched between two layers of phlogopite mica plate. The mica plates are infused with a high-temperature binder that allows forming during the manufacturing process. Final heat curing enhances rigidity and sets the shape permanently.\nThis construction delivers even heat distribution across the heater surface and supports a wide range of wattage and voltage configurations — including dual voltage, three-phase, and low inductance bifilar designs.\nTechnical Specification # With a thickness of 0.5 – 1.0mm and operating temperatures up to 500°C, mica heaters are the highest-temperature flexible heating solution available at SINOMAS.\nParameter Value Parameter Value Parameter Value Input voltage 12V – 690V Max temperature 500°C Min size 15 × 30mm Watt density ≤ 10 W/cm² Min temperature - Max size 600 × 1000mm Resistance tolerance ≤ ±5% Dielectric strength 30 kV/mm Thickness 0.5 – 1.0mm Parameter Value Temperature sensor RTD / Pt100, thermistor / NTC, thermocouple, thermal switch Installation Mechanical clamping (metal sheath optional) Circuit design Dual input voltage, three phase heater, bifilar design, etc. Lead wires Fiberglass Insulated high temperature wire Applications # Plastic processing: mold plates, hot platen presses, thermoforming Semiconductor processing: chamber walls, susceptors, process tooling Packaging, strapping, and heat-sealing equipment Commercial food service appliances: hot plates, convection surfaces, warming drawers Radiators and panel heaters Medical equipment: laboratory instrumentation, autoclave sterilization ","externalUrl":null,"permalink":"/mica-heater/","section":"Customized Heating Solution","summary":"","title":"Mica Heater","type":"page"},{"content":" Why Motors Need Space Heaters # Motor space heaters — also called winding heaters, anti-condensation heaters or strip heaters— must be installed to prevent moisture build-up on the electric windings of rotating electrical equipment during off time. Beyond condensation prevention, they ensure warm start-ups, extend bearing life, and add freeze protection to motors in cold climates.\nTypical applications include electric motors, generators, and alternators operating in damp or wet conditions: offshore and shipboard equipment, marine motors, dockside cranes, well pumps, and any equipment exposed to humid environments. Specifying a motor space heater at the design stage avoids the far greater expense of rewinding and unplanned downtime later.\nSilicone Heating Tape: Lower Temperature, Longer Life # To reduce the heater failure rate, smart motor manufacturers specify silicone heating tape instead. By spreading the same wattage over a much larger surface area, silicone heating tape operates at a low surface watt density — cool enough to touch with bare hands without burning. The service life of a properly sized silicone motor heater typically exceeds the service life of the motor itself.\nBecause silicone heating tape is applied directly to the winding end turns, it transfers heat more efficiently than a cartridge heater — often achieving the required anti-condensation protection at a lower power consumption.\nWhy Cartridge Heaters Fail — And Silicone Strip Heaters Don\u0026rsquo;t # Some motor manufacturers use metal or ceramic cartridge heaters for this purpose. Because cartridge heaters are physically small, they must run at a high surface watt density — and consequently high temperature — to deliver the required heat output. That high temperature accelerates heater degradation, and cartridge-style space heaters often fail within the first year of service.\nIn contrast the surface watt density of our SHT series gentle warming silicone heating tape is only 2.5 W/in2. You can feel the warmth but it is not so hot as to burn your hand. For applications requiring faster warm-up, we also offer the SHP series at 5 W/in².\nMotor Space Heater Part List # Our motor space heater part numbers consist of three parts: product series + size (WxL of the strip, inch) + voltage version\nProduct group: SHT for gentle warming (2.5 W/in²), SHP for fast heating (5 W/in²) Voltage version: A for 120V, B for 240V Other sizes and watt densities are available on request P/N (120V) P/N (240V) Size Watt W/in2 SHT1x10A SHT1x10B 1\u0026quot;x10\u0026quot; 25 2.5 SHP1x10A SHP1x10B 1\u0026quot;x10\u0026quot; 50 5.0 SHT1x12A SHT1x12B 1\u0026quot;x12\u0026quot; 30 2.5 SHP1x12A SHP1x12B 1\u0026quot;x12\u0026quot; 60 5.0 SHT1x20A SHT1x20B 1\u0026quot;x20\u0026quot; 50 2.5 SHP1x20A SHP1x20B 1\u0026quot;x20\u0026quot; 100 5.0 SHT1x24A SHT1x24B 1\u0026quot;x24\u0026quot; 60 2.5 SHP1x24A SHP1x24B 1\u0026quot;x24\u0026quot; 120 5.0 SHT1x30A SHT1x30B 1\u0026quot;x30\u0026quot; 75 2.5 SHP1x30A SHP1x30B 1\u0026quot;x30\u0026quot; 150 5.0 SHT1x40A SHT1x40B 1\u0026quot;x40\u0026quot; 100 2.5 SHP1x40A SHP1x40B 1\u0026quot;x40\u0026quot; 200 5.0 SHT1x60A SHT1x60B 1\u0026quot;x60\u0026quot; 150 2.5 SHP1x60A SHP1x60B 1\u0026quot;x60\u0026quot; 300 5.0 SHT2x20A SHT2x20B 2\u0026quot;x20\u0026quot; 100 2.5 SHP2x20A SHP2x20B 2\u0026quot;x20\u0026quot; 200 5.0 SHT2x30A SHT2x30B 2\u0026quot;x30\u0026quot; 150 2.5 SHP2x30A SHP2x30B 2\u0026quot;x30\u0026quot; 300 5.0 SHT2x40A SHT2x40B 2\u0026quot;x40\u0026quot; 200 2.5 SHP2x40A SHP2x40B 2\u0026quot;x40\u0026quot; 400 5.0 SHT2x60A SHT2x60B 2\u0026quot;x60\u0026quot; 300 2.5 SHP2x60A SHP2x60B 2\u0026quot;x60\u0026quot; 600 5.0 Request a Quote We also supply PT100 sensor probes for motor protection, including flexible PT100 and three-phase PTC thermistors.

Approximate heater wattage can be estimated as:\nW = 2DL\nWhere W = heat in watts, D = outside diameter of the stator lamination (inches), L = length of the stator core (inches).\nLarge motors (≥H315 frame): typically require one heating tape at each end — divide the calculated wattage between the two heaters. Beyond improving heat distribution across the winding, running two independently wired heaters also gives the motor a built-in backup: if one heater fails, the other continues to provide partial condensation protection until the failed unit is replaced.\nDC motors: may need 50–75% more heat than the formula suggests to stay dry.\nLength of the Strip: should run close to the full perimeter of the motor end. Overlapping the tape is not permitted under any circumstances.\nInstallation: How Motor Space Heater Is Wired # Flexible strip heater is laced around the outside diameter of the end turns on varnished windings. Heater leads are routed through the motor terminal box and connected to the available single-phase supply. In most installations, the heater is switched by a motor control circuit relay contact, which energizes the space heater automatically when motor power is disconnected. A timer or PLC output may also be used as an alternative control method, particularly for installations where the motor control circuit is not accessible.\n","externalUrl":null,"permalink":"/motor-space-heater/","section":"Customized Heating Solution","summary":"","title":"Motor Space Heater - Anti-Condensation Silicone Heating","type":"page"},{"content":"We kindly ask you to review the following before placing an inquiry or order.\nCustom design, no stock.

Polyimide (Kapton®) film is an organic material with very high dielectric strength, thin flexible profile and low thermal mass, while providing superior resistance to most solvents, acids, and radiation. Being translucent, polyimide (Kapton®) heaters allow easy visual inspection of the internal foil circuit structure.\nRequest a Quote Why Choose Polyimide (Kapton) Heaters # Flexible heaters come in several forms — polyimide (Kapton), silicone rubber, mica, and Teflon being the most common. Polyimide stands out in four areas that matter most for precision OEM applications.\nLow outgassing for vacuum and cleanroom environments. Polyimide (Kapton®) film has exceptionally low outgassing characteristics, making it the material of choice for vacuum chambers, space applications, and semiconductor manufacturing processes where volatile contamination is not tolerable. Silicone rubber heaters, by contrast, are not suitable for high-vacuum environments due to outgassing.\nLow electromagnetic interference for sensitive instrumentation. Polyimide heaters can be laid out in a bifilar configuration — adjacent traces carry current in opposite directions, cancelling the magnetic field that an ordinary heater would otherwise generate. Combined with the inherent low outgassing of the polyimide film, this makes the same heater suitable for both vacuum chambers and magnetically sensitive environments such as MRI gradient assemblies, NMR probes, atomic clocks, and cryogenic stages in quantum computing systems.\nThe preferred choice for low voltage, small form factor designs. Etched foil technology allows polyimide heaters to be designed with very low resistance values, making them ideal for 5V, 12V and 24V battery-powered or electronics-integrated applications. Combined with a thickness of just 0.2mm and a minimum bending radius of 0.8mm, polyimide heaters fit where no other heater can — directly onto PCBs, optical components, and precision sensors without adding meaningful weight or bulk.\nVisual transparency for inspection and design verification. Unlike opaque silicone rubber or mica heaters, polyimide film is translucent, allowing the etched foil meander pattern to be seen directly through the heater surface. This makes it easy to verify resistance trace layout, check for manufacturing defects, and confirm heating zone alignment — without disassembling the heater or relying solely on documentation.\nThe result is a heating element engineered for precision — where space, weight, and contamination control are non-negotiable.\nEtched Foil Element # Polyimide (Kapton) heaters make use of very thin (e.g. 50μm) etched metal (usually nickel-based alloy) foil as resistive element. The resistance trace to be etched is designed in CAD and transferred to the foil, which is then processed through acid spray to produce the desired resistance pattern.\nTaking advantage of the etched foil technology, complicated thermal profiles and a wide range of resistance values can be realized. A bifilar meander arrangement is possible, which is often required to eliminate parasitic inductance in the circuit.\nTechnical Specification # With a thickness of just 0.2mm and bending radius as small as 0.8mm, polyimide heaters are the thinnest flexible heating solution available from SINOMAS, operating up to 260°C.\nParameter Value Parameter Value Parameter Value Input voltage 5V – 400V Max temperature 260°C (note 3) Min width 8mm (note 1) Watt density ≤ 3.0 W/cm² Min temperature -50°C Max width 500mm (note 2) Watt tolerance ≤ ±5% Aluminum foil backing optional Thickness ≤ 0.2mm Insulation resistance \u0026gt; 100 MΩ Insulation overlayer optional Bending radius ≥ 0.8mm Parameter Value Temperature sensor RTD / Pt100, thermistor / NTC, thermocouple, thermal fuse, thermal switch Adhesive backing optional with PSA from 3M Circuit design dual input voltage, multiple heating zone, bifilar design, etc. Lead wires Teflon, silicone rubber, PI insulated cables, different plug sets / terminations available Dielectric withstand 1000 VAC, 1 minute Notes:\nThe minimum width of polyimide (Kapton) heater is 8mm for one side leads exit, 5mm for two side leads exit The maximum width of a polyimide (Kapton) heater is limited by the incoming roll of polyimide film. We can make wider heaters if the volume of demand is considerable. In principle, there is no limit on the length of the heater. The maximum operating temperature of 260°C applies to polyimide heaters without adhesive backing. Metal-Backed Polyimide Heaters # Aluminum or copper foil backing can be laminated to polyimide heaters to improve heat distribution and provide EMI shielding. Aluminum is the more common choice for thermal spreading, while copper offers superior EMI/EMC performance due to its higher electrical conductivity. This construction has been used successfully on polyimide heaters for medical CT scanners, particle accelerators, and similar precision equipment.\nApplications # Medical diagnostic instruments: Heat sample trays, reagent bottles, CPAP ventilator humidifiers, etc. Stabilize optoelectronic components Enable cold weather operation of outdoor electronics such as laptops, light boxes, ATMs Protect aircraft electronics and mechanical components in cold environments Preheating of EV battery packs for cold weather performance Magnetically sensitive instruments: MRI gradient assemblies, NMR probes, atomic clocks, quantum computing cryostats ","externalUrl":null,"permalink":"/polyimide-kapton-heater/","section":"Customized Heating Solution","summary":"","title":"Polyimide (Kapton) Heater","type":"page"},{"content":" PTFE (Teflon) heaters from SINOMAS combine the unique properties of PTFE coating with etched foil heating elements — delivering chemical resistance, non-stick surfaces, and a watt density of up to 6 W/cm², making them the preferred heating solution for corrosive, hygienic, and high-temperature industrial processes. PTFE (Teflon) heaters are formed by laminating etched foil heating elements between PTFE-coated fiberglass cloths. The resulting heater combines a rugged, non-stick, chemically inert surface with the flexibility and low thermal mass of a thin-profile heating element, in a total thickness of just 0.6 – 1.0 mm.\nRequest a Quote Why Choose PTFE Heaters # Flexible heaters come in several forms — polyimide (Kapton), silicone rubber, mica, and PTFE (Teflon) being the most common. PTFE heaters stand out in three areas no other flexible heater can match.\nFull chemical resistance. The PTFE coating is virtually inert across the entire pH range — from concentrated acids to strong alkalis. This makes PTFE heaters the only flexible heating solution suitable for direct immersion in corrosive process fluids such as acid baths, electrolytes, and plating solutions. Silicone rubber heaters offer IP67 waterproofing, but cannot withstand prolonged chemical exposure.\nNon-stick, hygienic surface. The inherent non-stick property of PTFE makes these heaters ideal for cleanroom, pharmaceutical, and food processing applications where residue buildup or contamination is not acceptable. The surface is odorless, hydrophobic, and easy to clean.\nBest performance among immersible flexible heaters. While mica heaters can match or exceed PTFE\u0026rsquo;s temperature range, their open construction is not sealed against liquid ingress. PTFE retains a fully sealed, non-stick surface while supporting continuous operation at 260°C — well beyond the limits of silicone rubber (200°C). This makes PTFE the only flexible heater type suitable for high-temperature and corrosive or hygienic environments.\nThe result is a heating element that works where others fail — in chemically aggressive, high-temperature, and hygiene-critical environments.\nTechnical Specification # Parameter Value Parameter Value Parameter Value Input voltage 12V – 400V Max temperature 260°C Thickness 0.6 - 1.0 mm Watt density ≤ 6.0 W/cm² (with heat sink) Min temperature -70°C Dielectric strength 1000–2500 VAC Watt tolerance ≤ ±5% Available colors black, brown, white, blue Surface non-stick, hydrophobic Parameter Value Temperature Sensor RTD / Pt100, thermistor / NTC, thermocouple, thermal switch Installation mechanical clamping, factory vulcanized to metal profiles Lead wires Teflon insulated, different plug sets / terminations available Approvals UL, CE Applications # Chemical processes: acid bath, electrolysis, plating, anodization and polishing — direct immersion in corrosive fluids Drum and tank heaters for chemicals and process fluids in dust-free environments Pipe and vessel heating in corrosive or hygienic environments Cleanroom and pharmaceutical heating where non-stick, residue-free surfaces are required Sterilization equipment and medical device manufacturing High-temperature industrial process heating up to 260°C where silicone or polyimide heaters are insufficient Replacing conventional immersion heaters in space-constrained installations ","externalUrl":null,"permalink":"/ptfe-teflon-heater/","section":"Customized Heating Solution","summary":"","title":"PTFE (Teflon) Heater","type":"page"},{"content":"","externalUrl":null,"permalink":"/series/","section":"Series","summary":"","title":"Series","type":"series"},{"content":" Silicone rubber heaters from SINOMAS deliver energy-efficient, precisely customized heating solutions for industrial and OEM applications.

Each has its strengths, but silicone rubber stands out in two areas that matter most for demanding OEM applications.\nTrue 3D conformability. Polyimide Heaters are flexible, but their flexibility is essentially two-dimensional — they bend, but do not stretch. Silicone rubber, by contrast, is elastic and can conform to compound curved surfaces, irregular housings, and complex 3D profiles that no other flexible heater can match.\nUnmatched customizability. Silicone rubber heaters can be custom-manufactured across virtually every dimension: surface finish, fiberglass or reinforcement-free construction, factory vulcanization onto metal profiles, integrated sensors and thermostats, custom connectors, and waterproof press-molding up to IP67. This depth of customization is simply not available with Teflon or mica heaters.\nThe result is a heating element that doesn\u0026rsquo;t just fit your device — it becomes part of it.\nEtched Foil vs Wire Wound Silicone Heaters # Silicone rubber heaters are available with etched foil elements or wire wound elements. Wire wound elements are wired manually according to a pre-defined meander via the guide pins on the pattern board. Except for irregular-shaped 3D profiles or long silicone heating tapes , wire wound technology has been phased out at SINOMAS.\nThe etched foil silicone rubber heater has exceptional heat transfer compared to wire wound heaters due to its large flat contact surface. It can deliver more even heat profiles with higher watt density, providing longer service life. Besides chemical etching, for quick prototyping or large sized heating blanket, we can also manufacture the foil element by laser cutting.\nFactory Vulcanized Silicone Rubber Heaters # Through a controlled process of heat and pressure, silicone rubber heaters can be factory vulcanized onto plain or black anodized aluminum, stainless steel or other metal profiles / panels. The silicone rubber actually flows into the microstructure of the metal profile forming a permanent bond and allowing the most efficient heat transfer.\nFactory vulcanized heated metal profiles have superior performance compared to any field installation. Factory vulcanization allows silicone rubber heaters to be designed at higher watt density and increases heater life. While the max watt density for standard silicone heater is 0.8 watts per cm2, factory vulcanization onto aluminum can support up to 3.0 watts per cm2 if the operation temperature is controlled.\nBy a similar process but without a heat sink, silicone rubber heaters can be factory vulcanized / pre-formed into a shape (mostly cylindrical or spiral) permanently. The preforming greatly facilitates the installation of silicone rubber heaters on pipes, cylinders of small diameter and inside fitting in metal drums.\nWaterproof Silicone Rubber Heaters (IP67) # Silicone rubber heaters are generally moisture-proof. Additional edge sealing will be enough for occasional water spray. If the heater pad is to operate under water for extended periods, the whole heater has to be press-molded to prevent moisture ingress through the fiberglass-reinforced edges. In this case, the thickness of heater pad will increase to about 2.6mm. Integrated temperature sensors are also possible.\nThe waterproof silicone rubber heaters are very useful for humid environments or even fluid heating where conventional immersion heaters can’t be installed due to space or mounting constraints. For example we have delivered silicone heating elements (2W/cm2) for portable hot water kettles, and heating blankets to maintain the temperature in greenhouses.\nSilicone Foam Insulation # Silicone foam insulation can be bonded to silicone rubber heaters to minimize heat loss and improve efficiency. Its closed-cell structure traps air, acting as a thermal barrier that directs heat toward the target surface instead of dissipating it into the surroundings — allowing faster heat-up and lower energy consumption. The foam layer also cushions the heater against mechanical shock and vibration, adds a degree of electrical insulation, and protects nearby components from excessive heat. Retaining silicone\u0026rsquo;s natural flexibility and temperature stability (typically -40°C to 150°C), it conforms easily to curved or irregular mounting surfaces — making it ideal for pipes and valves heating.\nInstallation Methods # Silicone rubber heaters can be installed in the following ways:\nPSA adhesive backing RTV Adhesive Paste Clamping or Compression Plates Hooks and Springs Hook \u0026amp; Loop Fasteners (Velcro) Lacing/Tying Temperature Rise Curve # The graph below illustrates the surface temperature rise of a standard silicone rubber heater at different watt densities. In the test the samples were hung freely in an enclosed space.\nThe graph is supposed to give you an idea of how fast the heating can be. It cannot replace engineering calculations and testing for your specific application. The temperature in the real situation will be related to many different factors.\n","externalUrl":null,"permalink":"/silicone-rubber-heater/","section":"Customized Heating Solution","summary":"","title":"Silicone Rubber Heater","type":"page"},{"content":"","externalUrl":null,"permalink":"/tags/","section":"Tags","summary":"","title":"Tags","type":"tags"},{"content":" Temperature sensing and thermal protection are essential for the safe and proper function of customer devices. Several types of components are available, each suited to different applications and purposes. The thermal components explained below can be integrated with our heating elements, or supplied separately as temperature sensor cable assemblies. Temperature Sensors # RTD / PT100 / PT1000 # RTDs (Resistance Temperature Detectors) rank among the most accurate sensors available for industrial temperature measurement. They operate on the principle that the electrical resistance of a metal — typically platinum — changes linearly with temperature. PT100 and PT1000 are the most widely used standardized RTD elements, covering a measurement range of approximately −200 °C to +850 °C.\nKey advantages include excellent long-term stability, high repeatability, and strong linearity. These characteristics make RTDs the preferred choice wherever high accuracy and traceable calibration are required. PT100 probes remain the most commonly specified RTD assemblies in industrial OEM applications.\nThermocouples # Thermocouples exploit the Seebeck effect: two dissimilar metal wires are joined at one end, generating a millivolt-level voltage proportional to the temperature difference between the measuring junction and the reference end. Their construction is simple, response is fast, and the measurable temperature range is exceptionally wide. Noble-metal thermocouples such as type B, R and S can measure temperatures approaching 1700 °C. Common calibration types include K (nickel-chromium / nickel-aluminium, also known as Chromel-Alumel), J, T, and E, each optimized for a different temperature range and accuracy class.\nType Conductors Range Notes K NiCr / NiAl −200 to +1260 °C most widely used, general purpose J Fe / CuNi 0 to +760 °C reducing atmospheres, lower cost T Cu / CuNi −200 to +370 °C cryogenic and high-accuracy low-temp E NiCr / CuNi −200 to +900 °C highest sensitivity N NiCrSi / NiSiMg −200 to +1260 °C better long-term stability than K S Pt-10%Rh / Pt 0 to +1480 °C high-temperature, lab reference R Pt-13%Rh / Pt 0 to +1480 °C similar to S, slightly higher output B Pt-30%Rh / Pt-6%Rh +250 to +1700 °C very high temperatures The relative drawbacks are the need for cold-junction compensation and somewhat lower absolute accuracy compared to RTDs.\nNTC Thermistors # NTC (Negative Temperature Coefficient) thermistors are manufactured from semiconductor ceramic materials whose resistance drops sharply as temperature rises, resulting in very high sensitivity. Their main advantages are small size, low cost, and fast response. Most commercial NTCs are used below 150 °C, although glass-encapsulated designs can operate at substantially higher temperatures.\nMost NTC thermistor failures occur in the packaging materials rather than in the ceramic sensing element itself. Glass encapsulation provides excellent hermetic sealing, electrical insulation, and chemical stability at high temperatures, allowing certain thermistors to operate at temperatures up to 250 °C.\nThermal Protection Components # The common logic of this component family is that they do not output temperature data. Instead, they actively intervene in the electrical circuit when a temperature threshold is reached, protecting equipment or limiting current without requiring any external control logic.\nThermal Fuse / Thermal Cutoff (TCO) # A thermal fuse is a one-shot over-temperature protection device. Its internal element — low-melting alloy or organic pellet — permanently opens the circuit when the ambient temperature exceeds the rated functioning temperature (Tf). The principal advantages are extreme simplicity, very low cost, and inherently reliable operation. The key limitation is that the device is non-resettable: once triggered, the entire component must be replaced. Rated temperatures typically range from 60 °C to 240 °C.\nThermal Protector / Temperature Switch # Most thermal protectors employ a bimetal element. As temperature rises, the differential thermal expansion of the bonded metals causes the element to snap, opening or closing a set of electrical contacts. Thermal protectors are available in either automatic-reset or manual-reset configurations.\nThe enclosure form factor of a thermal protector is determined by the installation environment and the technical requirements of the application. Widely used standard series include:\nKSD301: disc type, surface mounting, max current 10-16A, for temperature limiting in power circuit.\nTB02 \u0026amp; 17AM: miniature embedded protectors for motors, transformers and control circuits.\nPPTC Resettable Fuse # PTC devices belong to the broader thermistor family, whose resistance changes with temperature. Depending on the material system, PTC thermistors can be divided into ceramic (CPTC) and conductive polymer (PPTC) types. PPTC is often used as resettable thermal fuse for overcurrent and overtemperature protection in electronic circuits due to its low cold state resistance (a few mΩ).\nThe polymer matrix undergoes a phase transition at a characteristic switching temperature, causing the resistance to increase dramatically. For standard commercial PPTC components, this threshold typically falls in the range of 85 °C to 140 °C. This physical characteristic limits its suitability for elevated-temperature applications.\n","externalUrl":null,"permalink":"/temperature-sensor/","section":"Customized Heating Solution","summary":"","title":"Temperature Sensing \u0026 Protection","type":"page"},{"content":" Thick film heaters from SINOMAS integrate the heating element and structural substrate into a single unit — eliminating the thermal interface that limits conventional heater assemblies. The result is a compact, high-efficiency heating solution capable of watt densities up to 30 W/cm² and operating temperatures from 350 °C (steel substrate) to 800 °C (MCH), purpose-built for flow-through liquid heating, EV thermal management, and integrated industrial heating systems. Thick film heaters are available on two substrate families, each suited to different temperature ranges, thermal performance, and form factor requirements.\nStainless steel (SS430) — substrate rated to 500 °C; complete heater assemblies typically operate up to 350 °C, limited by lead wire termination. Weldable, mechanically robust, and the standard choice for high-volume liquid heating and panel heating. Alumina ceramic — up to 800 °C, high thermal conductivity, and excellent dielectric strength. The substrate of choice for fast-response heating in semiconductor, medical, and analytical instruments. See our Alumina ceramic heater page for details. Why Choose Thick Film Heaters # While most heating elements are built around an insulated foil or wire that must then be bonded to a separate heat sink, thick film heaters take a fundamentally different approach: the heating circuit is fired directly onto the structural substrate, making the heater and heat sink one integrated component.\nDirect substrate integration for superior heat transfer. In a conventional heater assembly, thermal resistance at the interface between heater and heat sink is a limiting factor. Thick film technology eliminates this interface entirely — the resistive circuit is fired directly onto the substrate, which conducts heat immediately into the target medium. This makes thick film heaters the preferred choice for flow-through liquid heaters, instant hot water dispensers, and any application where response time and efficiency are critical.\nSubstrate and geometry tailored to the application. Available on stainless steel or ceramic substrates and in flat, curved, or tubular form factors, thick film heaters can be designed as a structural component of the final product rather than an add-on element — reducing part count, assembly cost, and overall device size.\nHow Thick Film Heaters Are Made # Thick film manufacturing begins with the substrate, which is first coated with a glass-ceramic dielectric layer to electrically isolate the heating circuit. A resistive paste is then screen-printed onto the dielectric in the designed circuit geometry, followed by firing at high temperature (typically 800–900 °C) to fuse the paste into a durable, bonded circuit. Conductive terminal pads and a protective overglaze are added in subsequent print-and-fire cycles, completing the heating element as an integral part of the substrate.\nBecause the resistive circuit, dielectric, and substrate are all fused into a single fired assembly — with no adhesive bonds, mechanical clamps, or thermal paste — there is no interface thermal resistance between the heat source and the structural surface that delivers heat to the target medium.\nSteel Substrate: Why SS430 # Stainless steel is the most widely used substrate for thick film heaters, and within stainless steel grades, ferritic 430 is the industry standard. Two material properties explain this choice.\nThermal expansion compatibility # SS430 ferritic stainless steel has a coefficient of thermal expansion (CTE) of approximately 10.4 µm/m·K — moderately higher than the 6–8 µm/m·K of typical glass-ceramic dielectric coatings. This small mismatch is by design: after firing and cooling, the dielectric layer ends up in slight compressive stress, which ceramics tolerate very well. Higher-CTE substrates would produce tensile stress in the dielectric, eventually leading to cracking and delamination during thermal cycling.\nOxide layer adhesion # At thick film firing temperatures, SS430 forms a thin, dense chromium oxide (Cr₂O₃) layer on its surface. This oxide acts as a chemical bonding interface between the metal substrate and the glass-ceramic dielectric undercoat, producing strong, durable adhesion that withstands both mechanical stress and thermal cycling.\nWhy not 304 or 316? # Austenitic stainless steel such as 304 (CTE ≈ 17 µm/m·K) and 316 expand far more than the dielectric coating during firing and operation, producing tensile stress in the dielectric that leads to cracking and delamination over time. Their less stable oxide layer adds a secondary adhesion issue. For these reasons, ferritic SS430 is the dominant choice for thick film heater substrates.\nThick Film vs. Other Heater Types # Steel Thick Film Mica Heater Silicone Rubber Heater Max temperature 350 °C 500 °C 200 °C Watt density ≤ 30 W/cm² (typ. 5–20) ≤ 10 W/cm² ≤ 3 W/cm² (with heat sink) Substrate mostly SS430 Mica plate Silicone rubber Heat sink integration Built-in Separate Separate Form factor flat, curved, tube flat, curved complex 3D Best for Flow-through, panels Industrial heating Contoured surfaces Request a Quote When Use Alumina Substrate, Not Steel? # For thick film heaters, alumina substrate is the choice when:\nOperating temperature exceeds 350 °C Chemical resistance to acids, alkalis, or solvents is required Electrical isolation must withstand \u0026gt;1500 V The target media is purity-sensitive (medical, semiconductor, food contact) For lower-temperature, high-volume applications with good chemical environment, steel-substrate thick film offers better mechanical robustness and lower cost.\nApplications # AC line voltage heating: flow-through liquid heaters, radiators, heating panels Power electronics: braking resistors, load banks, energy dissipation assemblies Food \u0026amp; beverage: dispensers, instant hot water units, home appliances Automotive: EV battery heater, cabin heating, comfort systems Semiconductor: wafer processing equipment Packaging: heat-sealing and strapping machines Analytical instruments: DNA analyzers, laboratory heating blocks ","externalUrl":null,"permalink":"/thick-film-heater/","section":"Customized Heating Solution","summary":"","title":"Thick Film Heater","type":"page"}]
