Polyimide (PI) is a polymer of imide monomers, aslo know as warmth resistant movie or higher temperature movie. With their substantial heat-resistance, polyimide enjoys varied purposes in roles demanding rugged natural and organic components. Polyimide film is ideal for insulating circuit boards, substantial temperature powder coating and transformers production.
Polyimide film supplies outstanding electrical, thermal, bodily and chemical properties over a wide temperature selection in between -269ºC (-452ºF) and 400ºC (752ºF) making them superior for electrical insulation purposes. Polyimide film can be laminated, metalized, punched, fashioned or adhesive coated. BOPI movie has greater thickness tolerancem,highter actual physical, chemical,and electrical properties. It is the suggested option for purposes that require an all-polyimide movie with an excellent harmony of houses in excess of a wide variety of temperatures.
we can offer both standard and custom made polyimide movie solutions for a buyer dependent on their needs.
