6640 NMN insulation material-insulation paper

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.
