Polyimide (PI) is a polymer of imide monomers, aslo know as warmth resistant film or large temperature movie. With their high heat-resistance, polyimide enjoys various apps in roles demanding rugged organic and natural components. Polyimide film is perfect for insulating circuit boards, high temperature powder coating and transformers manufacturing.
Polyimide movie supplies outstanding electrical, thermal, actual physical and chemical properties over a wide temperature selection between -269ºC (-452ºF) and 400ºC (752ºF) generating them superior for electrical insulation programs. Polyimide movie can be laminated, metalized, punched, formed or adhesive coated. BOPI film has better thickness tolerancem,highter physical, chemical,and electrical houses. It is the advisable option for purposes that call for an all-polyimide film with an exceptional balance of properties in excess of a broad selection of temperatures.
we can supply both common and custom polyimide movie remedies for a client relying on their wants.
