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. |
