Unique combination of technical properties - Kapton® polyimide film

Polyimide film is particularly suitable for use at very high temperatures, as films made of other plastics usually cannot withstand these temperatures. The Kapton® films in our range Kapton® HN and Kapton® CRC can both be used for temperature class C (200 °C). Short-term you can even use Kapton® HN at -269 °C up to +400 °C. Additionally, Kapton® polyimide film is flame retardant according to UL 94 V-0 and self-extinguishing.
