SynTherm® – Insulating Materials Kapton® HN polyimide film

The polyimide film Kapton® HN consists of polycondensed aromatic Dianhydrid and aromatic Diamin.

Kapton® HN offers a unique combination of properties at the highest level, which are recommended for many applications in numerous branches. This PI films sustains it's excellent physical, electrical and mechanical properties within a wide temperature range. For short time it is also applicable for temperatures from -269 °C to +400 °C and is used in systems of class 240 °C. It has low flamability, is self-extinguishing and has no melting point. This PI-films offers a high chemical resistance - an organic solvent is unknown up to now. It has also a high resistance to beta and gamma radiation.
