TecpolyTM  IH  Polyimide film

 TecpolyTM IH Polyimide Film is made from the synthetic resin polymerized by pryomellitic anhydride and phenyl ether through salivating and continuous bi- directional drawing. It has excellent heat stability, mechanical and dielectric strength, radiation and chemical resistance, used as a perfect class- 180 electrical insulation material.

Features：

* High mechanical, electrical properties.

* Excellent flexibility.

* Lower coefficient of thermal expansion and lower moisture absorption.
