Epoxy phenolic resin plate is a hard plate insulating material made of impregnated paper, cotton cloth, glass cloth, impregnated phenolic resin and epoxy resin by baking hot press. Epoxy phenolic resin plate has high mechanical strength, dielectric properties, oil resistance and corrosion resistance. It is suitable for insulating parts in electrical machinery and electrical equipment with high demand, and can be used in damp environment and transformer. The heat resistance grade is B grade.

Epoxy phenolic resin board technology requirements:

1, epoxy phenolic resin plate appearance and surface should be smooth and smooth, do not allow impurities and other obvious defects, allow slight abrasions, the edges should be cut neat, and the end faces must not be stratified or cracked.

2, epoxy phenolic resin plate size: the area should not be less than 380 x 480 square millimeter. If special specifications are required, it can be produced in agreement with both suppliers and suppliers. The other data are detailed in the mechatronic standard. Epoxy phenolic resin board can be required by the demand side, processing various specifications of plates, tubes, pads, flanges, tiles, and special-shaped parts.
