Polyimide (PI) is a polymer of imide monomers, aslo know as warmth resistant film or substantial temperature movie. With their substantial warmth-resistance, polyimide enjoys various applications in roles demanding rugged organic and natural resources. Polyimide film is perfect for insulating circuit boards, large temperature powder coating and transformers manufacturing.
Polyimide film gives superb electrical, thermal, actual physical and chemical properties over a wide temperature assortment between -269ºC (-452ºF) and 400ºC (752ºF) generating them superior for electrical insulation apps. Polyimide film can be laminated, metalized, punched, formed or adhesive coated. BOPI movie has better thickness tolerancem,highter bodily, chemical,and electrical homes. It is the advisable choice for applications that call for an all-polyimide movie with an exceptional harmony of qualities above a extensive assortment of temperatures.
we can provide each regular and custom polyimide film solutions for a consumer dependent on their needs.
