Polyimide FEP Film (Similar to Kapton FN)

Properties

Polyimide F46 film is achieved by coating Polyimide film with F46 resin (FEP) on one side (FH) or double sides (FHF) and through the sintering process at high temperature, which combines the excellent properties of Polyimide film and F46 resin, high& low temp resistant, radiation resistant, excellent electrical properties, superior dimensional stability and heat sealable properties. It performs successfully in the wide range of temperature as low as -112F(-80c) and as high as +500F(+260c), 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.
