6640 NMN Polyester Film Polyaromatic Amide Fiber Paper Composite Material

High temperature resistant polyester film polyaramid fiber paper soft composite material is a three-layer (NMN) soft composite material made of polyester film (M) coated with high temperature resistant adhesive on both sides and pasted polyaramid fiber paper (N). . Has excellent heat resistance, dielectric properties and high mechanical strength. It is suitable for slot, interphase, interturn and gasket insulation in F/H-class motors and electrical appliances, especially for microwave oven motors and reactors. Passed the quality inspection of the Machinery Industry Electrical Material Product Quality Supervision and Inspection Center.
