Nomex Paper Polyimide Film Laminates

  6650 Polyimide film/polyaramide fibre paper flexible laminate (NHN) is a three-layer flexible laminate in which each side of polyimide film (H) is bonded with one layer of polyaramide fibre paper (Nomex). 6650 is presently the most advanced electric insulating flexible laminate. It has excellent thermal resistance, dielectric property and mechanical property. It is used for slot insulation, inetrphase insulation, interturn insulation and liner insulation in H class electrical motors and electrical appliances and it can also be used in some special places in Class B or F motors. 6650 passed SGS test for toxic and hazardous substance detection.
