Product Details

Epoxy-resin Prepreg DMD is a three-layer flexible material, produced by impregnating F-class DMD combined material into heat-resistant epoxy resin, and then cured to B-stage. DMD-P is for short.

 

Advantages:

It has comparatively good heat-resistance, sound dielectrically property and mechanical property. It is compatible with most gels, resins and varnishes. When cured to C-stage in moderate temperature, it will firmly adhere on the surfaces of copper or aluminium metals, without producing any small molecular volatiles.

 DMD-P for dry transformer cooper foil insulation

Applications:

The DMD-P is suitable for layer insulation of copper foil or aluminium foil on low-tension coils of dry-type transformers as well as suitable for slot and turn-to-turn insulation of B-class and F-class motors and electrical appliances.
