|
Properties |
|
Prepreg DMD is
formed in the process of precuring 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 precuring
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)-wrapped Low voltage coils in dry-type transformer and
