                   Pre-preg DMD-P

Properties and Application:

Prepreg DMD is made by the process of pre-curing the modified F-class DMD with Impregnation of Hi-temp resistant

B-stage Epoxy resin by baking, with long shelf life at room temp, low pre-curing temp & time, excellent electrical insulation,

bonding and heat-resistant properties. Its thermal Glass is F, widely used for liner insulation of copper foil (aluminum foil)-

wrappedLow voltage coils in dry-type transformer and slot insulation & phase insulation in B~F class Motor & electrical

appliances.
