6640 NMN Insulation Nomex Paper

6640 NMN Insulation Nomex Paper is a three-layer soft composite material. The outer two layers are DuPont's NOMEX insulation paper and the inner layer is polyester film. The insulation grade is F grade (155 ° C). It combines the excellent temperature resistance of NOMEX, the tensile tear strength and the excellent dielectric strength and mechanical properties of polyester film. Suitable for slot insulation, turn-to-turn insulation and gasket insulation for Class F motors.
