Polyimide Film

Polyimide Film

Polyimide film also nemed PI Film. It is made of polyimide acid solution is cast into film and stretched, and then amidated at high temperature. Polyimide film is 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 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.
