Products Description
DMD Electrical Insulating Paper Rolls is made of polyester film and polyester fiber non-woven soft composite material (F-grade DMD) impregnated with heat-resistant modified epoxy resin and baked.
DMD Electrical Insulating Paper Rolls is an electrical insulation material that combines DMD composite insulation paper material with epoxy resin pre-impregnation. It is commonly used in slot insulation, interlayer insulation and gasket insulation in electrical equipment such as transformers and motors.
Heat resistance grade: B (130°C) or F (155°C), depending on the resin formula
Adhesion: After heating and curing, it can be firmly bonded with copper, aluminum and enameled wire
Moldability: Suitable for coil hot pressing
Minimum order quantity: 1000KG
