Epoxy phenolic board is a rigid plate-shaped insulating material made of impregnated paper, cotton cloth, glass cloth, impregnated phenolic, epoxy resin, and baked and hot pressed.
Epoxy phenolic board has high mechanical strength, dielectric properties, oil resistance and corrosion resistance. It is suitable for insulating structural parts in electrical machinery and electrical equipment with high requirements, and can be used in humid environments and transformers. The thermal rating is B grade.
Technical requirements for epoxy phenolic board:
1. The appearance and surface of the epoxy phenolic board should be flat and smooth, no impurities and other obvious defects are allowed, and slight scratches are allowed. The edges should be cut neatly, and there should be no delamination or cracks on the end face.
2. Epoxy phenolic board size: It can be produced in various sizes. If special specifications are required, it can be produced by agreement with the supplier and the buyer. For other data, refer to the standards of the Ministry of Mechanical and Electrical Engineering.
Epoxy phenolic board can process various specifications of boards, tubes, gaskets, flanges, tiles and special-shaped parts according to the requirements of the buyer.
