Prepreg DMD

　

　

　

　

Properties and Applications:

The product is formed in the process of precuring the modified F-class DMD with Impregnation of hi-temp resistant Epoxy resin into B-stage by baking. With long shelf life at room temp, low precuring temp & time, showing excellent electrical insulation, bonding and heat-resistant properties. Its thermal Glass is F, widely used for liner insulation of copper foil (aluminum foil)-wrapped Low voltage coils in dry-type transformer and slot insulation & phase insulation in B~F class Motor & electrical appliances.
