Polyimide (PI) is a polymer of imide monomers, aslo know as warmth resistant movie or higher temperature film. With their large heat-resistance, polyimide enjoys various purposes in roles demanding rugged natural and organic components. Polyimide film is best for insulating circuit boards, higher temperature powder coating and transformers manufacturing.
Polyimide film gives excellent electrical, thermal, bodily and chemical properties over a broad temperature range amongst -269ºC (-452ºF) and 400ºC (752ºF) creating them superior for electrical insulation applications. Polyimide film can be laminated, metalized, punched, shaped or adhesive coated. BOPI film has much better thickness tolerancem,highter physical, chemical,and electrical houses. It is the advised option for applications that call for an all-polyimide movie with an superb harmony of houses over a broad assortment of temperatures.
we can provide equally standard and custom polyimide movie options for a buyer relying on their demands.
