DMD Epoxy Pre-impregnated Material

DMD Epoxy Pre-impregnated Material

Pre-impregnated Material DMD(Class F)formed in the process of precuring the modified F-class DMD with impregnation of Hi-temp resistant Epoxy resin into B-stage by baking

Characters
It is Class F(155°C)insulating material
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 liner insulation of copper foil (aluminum foil) low voltage coils in dry-type transformer and slot insulation and interphase insulation in B ~ F class motors and electrical appliances.
Special specification can be supplied according to customer request.
