Polyimide (Kapton) Heater

Backer Heating Technologies’ Kapton Heater units have been designed using an etched foil element sandwiched between two layers of thin Kapton (polyimide) film. They are extremely strong, flexible and light-weight. These heaters provide very precise heat distribution to any surface or material and are great for use in many unfavorable conditions.

Heater properties

Backer Heating Technologies designs, manufactures and distributes high-performance and top-of-the-line Kapton Heaters. These heaters work in all types of extreme temperatures:  lower temperature applications as low as -271°C (liquid helium) and higher temperatures up to 220°C. 

The product features:

- Excellent dielectric strength
- Good chemical resistance
- Resistant to most chemicals, acids and bases
- Excellent tear resistance
- Low out-gassing
- Small and flexible radius
- Resistant to radiation and fungus

Kapton Heater units from Backer Heating Technologies are available in a wide array of configurations to suit many different requirements across various industry sectors. In addition to our standard Kapton heaters, we also provide custom heaters in various shapes, sizes and power densities.
