NMN Composite material is three- layer composite material with Nomex® paper adhered to both sides of polyester film.It has excellent heat resistance and tear resistance by its paper and good dielectric strength and mechanical strength by its film.The product is used as insulation material for F/H class electrical machines.
High thermal class: typically Class F (155°C) or even Class H (180°C)
Excellent electrical insulation performance: high dielectric strength and stability
Good mechanical properties: high tensile strength and wear resistance
Outstanding thermal aging resistance: stable performance during long-term operation
Good processability: easy for punching, bending, and forming
NMN composite material is widely used in medium- and high-voltage motors, generators, and transformers, mainly for:
Motor slot insulation
Phase insulation
Turn insulation
Winding liner insulation
Transformer layer and interphase insulation
