Polyimide (PI) is a polymer of imide monomers, aslo know as warmth resistant film or substantial temperature movie. With their high heat-resistance, polyimide enjoys varied apps in roles demanding rugged natural components. Polyimide film is best for insulating circuit boards, high temperature powder coating and transformers production.
Polyimide movie provides superb electrical, thermal, physical and chemical properties over a broad temperature variety in between -269ºC (-452ºF) and 400ºC (752ºF) producing them superior for electrical insulation purposes. Polyimide film can be laminated, metalized, punched, formed or adhesive coated. BOPI movie has far better thickness tolerancem,highter bodily, chemical,and electrical houses. It is the recommended choice for purposes that need an all-polyimide movie with an superb balance of qualities above a vast assortment of temperatures.
we can provide both regular and personalized polyimide movie options for a client based on their requirements.
