| | 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.
