Silicone Etch Foil Heaters

Efficient. Reliable. Flexible. Combine the structural stability and flexibility of silicone rubber with the precise heating controls of etched foil, and you get Fullchance's silicone etch foil heaters. The high-strength fiberglass reinforced silicone rubber housing can be vulcanized to conform to the contours of diversely shaped parts. Flexible silicone rubber heaters offer up to twice the wattage of wire wound options.


Fullchance's silicone rubber etched foil heaters offer greater heat coverage and up to twice the wattage density of wire wound. When watt density matters, Fullchance’s state-of-the-art flexible circuitry allows designers to distribute wattage and create complex heat distribution patterns with silicone rubber. 

- Etched foil provides options for variable watt density and complex heat patterns.

- Etching circuits is an efficient means for manufacturing in high quantities.

- Foil thickness ranges from .0005″ to .004″ depending on your required resistance.

- Different foil material types can be used depending on the heater resistance needed.

- Etched designs are excellent for applications requiring watt densities greater than 5 watts/in2.

- Excellent choice for heaters that require multi-zoned wattages or heaters that have many holes or cutouts.

- Offers excellent circuit repeatability.

- Elimination of edge loss due to compensation using distributed wattage.

Engineering services and consultation are available on every custom heating element order. Contact a specialist today for details about our flexible silicone rubber heaters, or other custom heating applications.


Computer designed, chemically etched foil tracks are laminated between thin sheets of silicone to give precise, even heating. Suitable for both low and high volume production, Etch Foil Silicone Heaters have rapid heat up properties with precise temperature control.

Suited to applications where high power densities are required, etch foil silicone heaters offer a more precise form of heating than their wire wound counterparts owing to wider heated tracks.

  • Short lead time, fast delivery – shenzhen and worldwide
  • Wire wound or etch foil silicone heaters in mat or pad design
  • Precise even surface heating for regular or irregular shapes
  • Custom design – heat loss calculations determine exact requirement
  • Flexible, lightweight and thin – space and weight reduced
  • Moisture and chemical resistant
  • Temperature range -60°C to +230°C

    Silicone Heaters – Etch Foil Flexible Silicone Heaters


Etched foil heaters are suited to both high and low volume applications, applications which require a rapid heat-up times or where even surface heating is required. Etch foil silicone heaters have been regularly used for the following purposes; telecommunications, satellite dishes, laboratory equipment and commercial building to name just a few.


  • Custom designed to operate up to 600 volts.
  • Resistive element and functions with AC and DC voltage sources.
  • With dual voltage, you get the same heater for 110 and 220 volt equipment.


  • Distributed Wattage can be used to compensate for heat loss and create uniform temperature in application. Operate more efficiently by applying heat were it is needed.
  • Fullchance heaters can be designed with multiple zones, controlled and operated independently. This approach saves time and minimizes design iterations in product development.


  • Fullchance can be supplied with a variety of sensors: thermocouples, thermistors and RTDs.
  • Our design team can assist you with custom mounting options to achieve optimal results.
  • Sensors can be mounted over heated and non-heated sections. Most thermocouples, thermistor or RTD sensors can be incorporated into the Fullchance assembly process.

Thermostats & Thermal Fuses

  • Designed to provide maximum efficiency for your application.
  • Large selection of bimetallic thermostats to perform control and safety functions. Our thermostats are limited to 240 volts and 15 amps.
  • Thermostats can be mounted with the sensory side exposed to the ambient air inside the enclosure.
  • Thermostats can be mounted over a heated or non-heated section. By placing the thermostat over a heated section, the thermostat will limit the temperature of the heating element itself and is a great back-up temperature controller.

Connecting Leads

Typical Options Include:

  • Teflon® (TFE) insulated.
  • Silicone rubber insulated leads.
  • HPN (lamp or zip cord).
  • SJO cord.

Leads can be sleeved in Silicone coated fiberglass, heat shrink or stainless steel overbraid. Connectors can be added for attachment to your applications.

Attachment Methods

  • Pressure Sensitive Adhesive for attachment at customer location.
  • Heaters can be vulcanized to conform to the contours of a variety of shapes and sizes of metals and plastics. This method provides intimate contact and superior heat transfer to the part being heated.
  • Attach and detach materials – over and over again. Snaps, Spring Clasps, Hooks, Velcro® – just about any fastener can be incorporated into the design for easy attachment to almost any part configuration.

Thermal Insulation

Fullchance heaters can be supplied with a variety of insulation types, normally 1/8” to 1/2” medium density Silicone rubber sponge. Heatron has devised sponges that resist compression setting for applications where the combined heater and sponge will be under pressure.
