Polyimide (PI) is a polymer of imide monomers, aslo know as warmth resistant movie or higher temperature film. With their substantial warmth-resistance, polyimide enjoys various programs in roles demanding rugged natural and organic supplies. Polyimide film is best for insulating circuit boards, high temperature powder coating and transformers production.
Polyimide movie gives superb electrical, thermal, actual physical and chemical properties over a vast temperature range between -269ºC (-452ºF) and 400ºC (752ºF) making them superior for electrical insulation applications. Polyimide movie can be laminated, metalized, punched, shaped or adhesive coated. BOPI film has greater thickness tolerancem,highter physical, chemical,and electrical homes. It is the advised selection for apps that call for an all-polyimide film with an superb stability of homes more than a wide variety of temperatures.
we can offer equally common and custom polyimide film remedies for a customer relying on their demands.
