Product Description

Description 
Polyimide (PI) is a polymer of imide monomers, aslo know as heat resistant film or high temperature film. With their high heat-resistance, polyimide enjoys diverse applications in roles demanding rugged organic materials. Polyimide film is ideal for insulating circuit boards, high temperature powder coating and transformers manufacturing.
Polyimide film provides excellent electrical, thermal, physical and chemical properties over a wide temperature range between -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 better thickness tolerancem,highter physical, chemical,and electrical properties. It is the recommended choice for applications that require an all-polyimide film with an excellent balance of properties over a wide range of temperatures.
we can provide both standard and custom polyimide film solutions for a customer depending on their needs.
