       Polyimide film coated with FEP resin

Properties and Applications  

Polyimide FEP film (PIFEP) is Polyimide film coated with FEP resin on one side or double sides through the sintering

process at high temperature, which combines the excellent properties of Polyimide film and FEP resin, high& low temp

resistant, radiation resistant, excellent electrical properties, superior dimensional stability and heat sealable properties.

Widely used for insulation in motor, electrical apparatus and wrapping of cable and magnet wire. It can be melt and

formed soon as desired at defined temperature. The following table lists the main technical data of common types of

PIFEP, there are many other combinations, such as 939, 029,039 etc, please feel free to contact us if necessary.
