FEP Coated Polyimide Film for Electrical Insulation

FEP Coated Polyimide Film for Electrical Insulation


Polyimide FEP film  is Polyimide movie coated with FEP resin on a single side or double sides by means of the sintering method at high temperature, which brings together the superb houses of Polyimide movie and FEP resin, large& lower temp resistant, radiation resistant, superb electrical homes, superior dimensional security and heat sealable homes.



•High temperature electrical insulation

•Cut-by means of resistant

•High dielectric energy

•High bond energy


•Wire and cable insulation for downhole pumps and aircraft electrical systems.

•Turn insulation in Motors and Turbines.

•CZPTal insulation of Versatile Heater.
