Polyimide Film
Polyimide Film
-HN Pure film
-FN FN is type HN coated with FEP fluorocarbon resin, it is heat sealable grade.
-CR Crona resistant. Type CR can withstand partial discharge which can cause breakdown of the insulation material.
-FCR Type FCR is polyimide film CR coated with FEP fluorocarbon resin, can withstand corona
discharge, as wire insulation it helps to reduce partial discharge.
Other types:
-High thermal conductivity
-Moldable
-Black anti-static
-Aluminized polyimide film
