DMD环氧预浸渍材料

DMD Epoxy Pre-impregnated Material

DMD epoxy pre-impregnated material is made of polyester film and nonwoven polyester fabric compounded by F grade heat-resisting adhesive and impregnated with heat-resisting epoxy resin through baking. The product has level surface, stable performance, and high bonding strength to copper foil and aluminum foil; it hardly has low molecule volatile and has lower shrinkage in vacuum drying after being surrounded by copper and aluminum foil. It is an ideal slot, interturn and interlayer insulating material of dry type power transformers, reactors and other motors.
