Polyimide (PI) is a polymer of imide monomers, aslo know as warmth resistant film or large temperature film. With their large warmth-resistance, polyimide enjoys assorted applications in roles demanding rugged natural and organic supplies. Polyimide film is excellent for insulating circuit boards, substantial temperature powder coating and transformers production.
Polyimide film provides outstanding electrical, thermal, physical and chemical properties over a extensive temperature variety in between -269ºC (-452ºF) and 400ºC (752ºF) making them superior for electrical insulation purposes. Polyimide movie can be laminated, metalized, punched, shaped or adhesive coated. BOPI film has better thickness tolerancem,highter actual physical, chemical,and electrical properties. It is the recommended selection for purposes that require an all-polyimide movie with an excellent equilibrium of properties more than a vast range of temperatures.
we can provide each normal and custom polyimide movie options for a buyer based on their requirements.
