Polyimide (PI) is a polymer of imide monomers, aslo know as warmth resistant film or substantial temperature movie. With their higher heat-resistance, polyimide enjoys diverse purposes in roles demanding rugged natural materials. Polyimide film is ideal for insulating circuit boards, high temperature powder coating and transformers manufacturing.
Polyimide film provides superb electrical, thermal, bodily and chemical properties over a wide temperature selection among -269ºC (-452ºF) and 400ºC (752ºF) producing them superior for electrical insulation programs. Polyimide movie can be laminated, metalized, punched, shaped or adhesive coated. BOPI movie has much better thickness tolerancem,highter physical, chemical,and electrical qualities. It is the advisable option for purposes that need an all-polyimide movie with an outstanding stability of homes in excess of a wide assortment of temperatures.
we can give both regular and custom made polyimide movie options for a customer dependent on their needs.
