DMD Epoxy Prepreg

DMD Epoxy Prepreg is a flexible insulation material with a sandwich structure: a middle layer of polyester film for electrical strength and tear resistance, surrounded by two layers of polyester non-woven fabric for flexibility and resin absorption. Impregnated with epoxy resin and baked to a semi-cured (B-stage) state, it maintains good resin flowability and low volatility during high-temperature curing, forming a durable structure that provides both mechanical protection and electrical insulation.
