1.    DESCRIPTION

This is a heat sealable film which is made by polyimide film with one side or double side FEP coated. When combined with FEP resinthe Polyimide film remains excellent heat and electrical properties. This kind of film is widely used in high temperature wire manufacturing.

 

2.    FEATURES

 high temperature resistance,

 high dielectric strength

 heat sealable properties

 radiation retardant

 

3.    APPLICATIONS

Wire & cable insulation when used in severe environment such as high temperatureunder water and oil.

Turn insulation in motors and generators
