  phenolic bakelite sheets plate board is a laminated paper board formed through drying and heat pressing after the insulation dipping paper dips into the PF resins. This product is used as insulation structure component for electric engine and electric equipment of higher mechanical performance, as well as used in transformer .   The surface should be flat, tidy and smooth. The bubble, impurity or other evident defect is not allowed. The slight scrape is allowed. The edge should be cut tidy. There is no delamination or crackle on end surface.   Size of phenolic bakelite sheets plate board: 1020x2070mm
Thickness of phenolic bakelite sheets plate board:0.5-120mm     For more information, please feel free to contact Chrystal Zhai:
