Epoxy-resin Prepreg DMD electrical insulation

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. Material: Composite Polymer Application: High Temperature Tensile Strength: 10.4Mpa Color: red,natural Thickness: 0.15-0.40mm Certification: ROHS Sample: Sample Avaliable Usage: Insulation Protection BDV: ≥7.0-10.0kv temperature index: ≥155℃ curing time: 130℃ 5h; 140℃ 4h; 150℃ 3h

Product Details

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.


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.
