Epoxy-resin prepreg DMD
Epoxy resin prepreg DMD is composited by F-Grade heat-resistant adhesive for two sides of polyester non woven fabrics and one layer of polyester film,then impregnate with heat resistant epoxy resin and bake it.This product with smooth surface and stable performance.It can be bonded with copper foil and aluminum foil very well.After wrapping with copper(aluminum) foil,there almost no low-molecular-weight volatilize and with low shrinkage in the vacuum drying environment.Epoxy resin prepreg DMD should be the ideal insulation material for dry type power transformers, reactors and other motors.
