Polyimide Film & all-Polyimide Etch Foil Heaters
Ultra Thin. Low Mass. DuPont™ Kapton® Polyimide Film and All-Polyimide flexible etched foil heaters are ideal for applications requiring low outgassing, operating in extreme environments or where space and weight allowances are limited. The material has high dielectric strength and excellent dimensional stability for higher watt density and temperature applications, while providing lower operating costs and increased throughput.

DuPont™ Kapton® Polyimide Film and All-Polyimide flexible etched foil heaters are constructed using foil as the element and chemical etching to delineate the element pattern. Advanced circuit imaging and printing combined with chemical etching allows designers the flexibility to distribute wattage and create multiple heat patterns within a single heater.
Engineering services and consultation are available on every custom flexible heater order. Contact a specialist today for details.
About Heatflex Flexible Etched Foil Heaters
Heatflex is one of Fullchance's most popular heater designs. The flexible substrate housing and etched foil or wire-wound heating elements provide maximum flexibility for your design in size, configuration and technical specifications. Fullchance's flexible Heatflex heaters are suitable for a wide range of industrial and commercial applications.


Heatflex flexible heaters can accommodate a wide range of design configurations, attachments, leads and sensors to meet your project requirements.


  • 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.
  • Heatflex heaters can be designed with multiple zones, controlled and operated independently. This approach saves time and minimizes design iterations in product development.


  • Heatflex 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 Heatflex 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.

Heatflex heaters provide sensory control, including partial temperature capacity. This serves to limit the temperature of the heating element itself, is a great back-up temperature controller, and it is ideal for freeze prevention and condensation build-up in outdoor electronic enclosures.

  • 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.

Connecting Leads

Typical Options Include:

  • Teflon® (TFE) insulated, 19-strand silver plated copper conductor.
  • Silicone rubber insulated leads.
  • HPN (lamp or zip cord).
  • SJO cord.

Leads can be sleeved the leads in Silicone coated fiberglass, heat shrink or stainless steel overbraid.

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. Fullchance has devised sponges that resist compression for applications where the combined heater and sponge will be under pressure.
