SynTherm® – Insulating Materials SynTherm® H (Polyimide film)
SynTherm® H is a polyimide film manufactured with the raw materials of pyromellitic dianhydride and 4.4-diaminodiphenyl ether synthetic resin.
SynTherm® H offers a unique combination of properties at the highest level, which are recommended for many applications in numerous branches. SynTherm® H 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 it is used in systems of class H. It has low flamability, is self-extinguishing and has no melting point. SynTherm® H offers a high chemical resistance - an organic solvent is unknown up to now. It has also a high resistance to beta and gamma radiation.
Application
SynTherm® H is especially for applications with high operating temperatures for which other films are not applicable.
