Manufacturer Electrical Used Epoxy-resin Prepreg insulation Material Used For Transformer/Motor
The electrical-use sort insulating prepreg which we produced is combined with polyestet film and
polyester fiber, pregnated with Epoxy Resin up to F class insulating material. They are widely used in
the layer insulation of transformer, wire casing insulation and phase coil insulation of motor. The
product is bright in color, complete in specification with the stable quality.
Insulation prepreg DMD
Pre-impregnated DMD composite insulation paper (Class F) is formed in the process of precuring the
modified F-Class DMD with Impregnation of high-temp resistant epoxy resin into B-stage by baking.
Pre-impregnated DMD insulation paper
With high insulating properties,,Pre-impregnated DMD Insulation Paper is used for the insulating
slots, liners and layers for F-grade motor and transformer.
DMD Insulation paper Characters:
Pre-impregnated DMD Insulation Paper is Class F (155 degree) insulating paper. This product has long shelf
life at room temperature, low precuring temperature and time, showing excellent electrical insulation, bonding
and heat-resistant properties.
DMD insulation paper Application:
It is used for the liner insulation of copper foil/aluminum foil, wrapped low voltage coils in dry-type transformer
and slot insulation and interphase insulation in Class B-F motor and electrical appliances
