Electric Insulation Polyimide Film The Coverlay for FPC

Electric Insulation Polyimide Film The Coverlay for FPC

Polyimide (PI) is a polymer of imide monomers, aslo know as heat resistant film or large temperature movie. With their higher warmth-resistance, polyimide enjoys assorted programs in roles demanding rugged natural and organic supplies. Polyimide film is perfect for insulating circuit boards, higher temperature powder coating and transformers production.
Polyimide movie provides excellent electrical, thermal, physical and chemical properties over a vast temperature assortment among -269ºC (-452ºF) and 400ºC (752ºF) making them superior for electrical insulation applications. Polyimide film can be laminated, metalized, punched, formed or adhesive coated. BOPI film has much better thickness tolerancem,highter physical, chemical,and electrical houses. It is the advisable choice for programs that need an all-polyimide movie with an superb equilibrium of homes over a wide variety of temperatures.
we can supply each regular and personalized polyimide film options for a buyer dependent on their requirements.
