NMN (6640)
Polyester Film &
NOMEX Amide Fiber Paper Composites
Description and Applications:
NMN (6640) is laminated by 2-layer of Nomex and 1-layer 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- F 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 155℃ for class-F insulation.
Excellent tear resistance and flexibility, easy to be applied.
Low dielectric dissipation, it can work in harsh condition.
