Polyimide / Kapton® Heaters
Epec’s Polyimide Flexible Heaters are your solution to heating curved and irregular surfaces. Due to their design, polyimide heaters can be extremely thin, as low as 0.007”, excluding any type of affixing adhesives. The etched circuit is pressed between 2-layers of polyimide film with either an FEP adhesive or an acrylic adhesive depending on the thermal characteristics required of the heater.
The design of a polyimide heater offers dimensional stability, superior tensile strength, and overall improved resilience. Polyimide is also resistant to most chemicals.
We offer multiple heating elements for polyimide heaters, such as stainless steel 304, CuNi44, and Inconel600, with excellent dielectric properties and operating environments between -319°F (-195°C) and 392°F (200°C). Kapton heaters also offer a quicker thermal transfer than silicone rubber heaters.
