Polyimide (PI) is a polymer of imide monomers, aslo know as warmth resistant film or large temperature film. With their substantial warmth-resistance, polyimide enjoys assorted apps in roles demanding rugged natural resources. Polyimide film is excellent for insulating circuit boards, high temperature powder coating and transformers manufacturing.

Polyimide film gives outstanding electrical, thermal, bodily and chemical properties over a vast temperature assortment in between -269ºC (-452ºF) and 400ºC (752ºF) generating them superior for electrical insulation applications. Polyimide film can be laminated, metalized, punched, shaped or adhesive coated. It is the advisable option for programs that demand an all-polyimide film with an superb harmony of houses over a wide selection of temperatures.
 we can offer the two regular and personalized polyimide movie remedies for a consumer dependent on their wants.
