Product Description
6640 composite material is made of two layer of du pont nomex paper with one of polyester film
Class f insulation (155ºC)
Excellent heat resistance, dielectric property and mechanical strength \good cutting and overhead resistance, high stiffness good compatibility with insulation varnish.
As slot, interturn and liner insulation, f-grade motor and electric appliances.
Nmn: 0.15mm-0.40mm form: Rolls
Width 914mmm, sheets strips (width>5mm)
Nmn insulation material-insulation paper consists of pet film, covered on both sides with calandered nomex1 paper. Nmn is a combined flexible material of thermal rating class f (155) with excellent mechanical properties like high tensile strength and high edge tear resistance combined with high electrical strength.
Nmn has a smooth surface which allows a trouble free manufacture of low voltage motors where coil shooting machines are used.
Nmn is mainly used as a slot liner, slot closure and phase insulation in the production of low voltage motors. Besides this nmn is used as interlayer insulation in transformers and other electrical machines and appliances.
