6650 NHN Polyimide Film & NOMEX® Amide Paper Composites

6650 NHN Polyimide Film & NOMEX ® Amide Paper Composites are a family of 3-ply laminates of NOMEX ® bonded to one side or both sides of polyimide film. It has not only excellent dielectric and mechanical strength of polyimide film, but the better tear resistance and excellent varnish adsorption NOMEX ® Amide paper, so it is a reliable class- H insulation material for electrical machines.

Characteristics:

*High mechanical strength, good dielectric strength with thinner slot insulation ply.

*Good thermal stability, it can work for a long term under 180 for class-H insulation.

*Excellent tear resistance and flexibility, easy to be applied.

*Low dielectric dissipation, it can work in harsh condition.
