Specifications
Pre-impregnated DMD:
F Grade DMD
0.18-0.45mm
Excellent dielectric and mechanical property, high tensile strength
F-grade Epoxy Pre-impregnated DMD
Pre-impregnated DMD composite insulation paper (Class F) is formed in the process of precuring the modified F-Class DMD with Impregnation of high-temp resistant epoxy resin into B-stage by baking.
Pre-impregnated DMD insulation paper
With high insulating properties, Pre-impregnated DMD Insulation Paper is used for the insulating slots, liners and layers for F-grade motor and transformer.
Characters:
Pre-impregnated DMD Insulation Paper is Class F (155 degree) insulating paper. This product has long shelf life at room temperature, low precuring temperature and time, showing excellent electrical insulation, bonding and heat-resistant properties.
Application:
It is used for the liner insulation of copper foil/aluminum foil, wrapped low voltage coils in dry-type transformer and slot insulation and interphase insulation in Class B-F motor and electrical appliances
