    详细说明

    F-DMD is a three-layer flexible laminate insulating material consisting of polyester fiber non-woven fabric/polyester film/polyester fiber non-woven fabric. The used adhesive is F Class and acid-free and temperature resistant. It shows excellent electric insulating properties, heat resistance,mechanical strength and impregnated properties. It can be used in insulating slots, gaskets for electric machinery and interlayer insulation in transformers.
