Product Description
6641 F grade DMD polyester film polyester fiber non-woven soft composite material is made of polyester fiber non-woven fabric and polyester film. The three-layer composite material bonded by F grade resin has a temperature resistance rating of 155°C. It is mainly used for slot insulation, turn-to-turn insulation, gasket insulation, transformer insulation of Y2 series motors or other low-voltage motors. It can also be used for F-class electrical coil insulation.
