Thermal Class C over 180°C
Polyimide film – Kapton® HN
Du Pont Kapton® HN is a high performance film for extreme conditions and highest demands. Kapton® is successfully used in systems with temperatures up to 400°C. However, Kapton® has a guaranteed long-term temperature resistance of +230°C and thus belongs to thermal class C. Furthermore, Kapton® has no melting point and only begins to carbonise above 800°C. In addition, Kapton® is extremely flame retardant and has a high chemical resistance.
Polyimide film is used when other plastic films fail. Applications include chip fabrication, fuel cell stack fabrication, medical technology, electronics applications and aerospace.
