Polyimide (PI) is a polymer of imide monomers, aslo know as warmth resistant movie or high temperature film. With their high warmth-resistance, polyimide enjoys varied applications in roles demanding rugged natural components. Polyimide film is ideal for insulating circuit boards, large temperature powder coating and transformers manufacturing.
Polyimide movie offers outstanding electrical, thermal, actual physical and chemical properties over a extensive temperature selection among -269ºC (-452ºF) and 400ºC (752ºF) generating them superior for electrical insulation purposes. Polyimide movie can be laminated, metalized, punched, shaped or adhesive coated. BOPI film has greater thickness tolerancem,highter actual physical, chemical,and electrical houses. It is the advisable selection for purposes that demand an all-polyimide film with an exceptional stability of qualities in excess of a extensive assortment of temperatures.
we can provide the two standard and custom made polyimide film answers for a client relying on their needs.
