Bismaleimide laminated glass cloth board is made of alkali free glass cloth immersed with modified bismaleimide resin by baked and pressed. It has good mechanical property ,dielectric property , moisture resistance and machinability. The heat resistant class is H that suitable for insulation structure of high temperature resistant motor and electric appliance such as motor slot wedges, gaskets and outlet plates, dry transformer bracing, gaskets and junction plates, etc.
Requirement:
Chocolate brown, smooth surface without bubbles, impurity and obvious defects. It allows slight bruise. The edges should be cut neatly without layering and crack.
