Friction and release coated polymide film for electrical insulation and the process of manufacturingthe same

摘要

Polymide film possesses a unique combination of properties that make it ideal for a variety of applications in many different industries. The ability of Polymide film to maintain its excellent physical, electrical and mechanical properties over a wide temprature range has opened new design and application areas to palstic films. This invention relates to manufacture of "Friction and Release Coated Polymide Film for electrical insualtion and the process for manufacturing the same". It consists Polymide film coated with a special friction coating on one side and controlled release coating on the other side of the Polymide film. Friction coating gives the Polymide film higher varnish absorption properties and the release coating helps in the ease of application.
