Polyimide FEP Film (Similar to Kapton® FN)
Properties
Polyimide FEP(F46) film (similar to Kapton® FN) is made of coating Polyimide film with FEP resin(F46) 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 FEP resin of high& low temp resistant, radiation resistant, corrosion 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). Polyimide FEP(F46) film (similar to Kapton® FN) widely used for insulation in motor, electrical apparatus and wrapping of cable and magnet wire, heater manufacture etc.
