Polyimide (PI) is a polymer of imide monomers, also known 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. BOPI film has better thickness tolerances, higher physical, chemical, and electrical properties.
Core Features
- Excellent thickness tolerance property
- Temp resistance from -269ºC to over 400ºC
- Easy coating property
- Excellent balance of electrical, chemical and physical property
- Flame and Radiation retardant
