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 slot insulation &
phase insulation in B~F class Motor & electrical appliances. |
