NMN insulation paper

NMN insulation paper:Insulation class F (155C),Excellent Heat Resistance,dielectric property and Mechanical Strength.
ISO9001
NMN insulation paper consists of PET film, covered on both sides with calandered Nomex 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.
