Black Polyimide Film for Lithium Battery Cladding

Black Polyimide Film for Lithium Battery Cladding

Polyimide (PI) is a polymer of imide monomers, aslo know as warmth resistant film or substantial temperature movie. With their substantial warmth-resistance, polyimide enjoys various applications in roles demanding rugged natural and organic resources. Polyimide film is ideal for insulating circuit boards, higher temperature powder coating and transformers producing.
Polyimide film offers exceptional electrical, thermal, physical and chemical properties over a extensive temperature variety in between -269ºC (-452ºF) and 400ºC (752ºF) making them superior for electrical insulation apps. Polyimide movie can be laminated, metalized, punched, fashioned or adhesive coated. BOPI film has far better thickness tolerancem,highter bodily, chemical,and electrical homes. It is the advised decision for purposes that need an all-polyimide film with an exceptional stability of properties above a extensive variety of temperatures.
we can give the two normal and custom polyimide movie solutions for a buyer based on their requirements.
