The modified bismaleimide glass cloth laminate is made by an electrician using an alkali-free glass cloth dipped modified bismaleimide resin, which is baked and hot pressed.
This product is made by electrician's alkali-free glass cloth impregnated with modified bismaleimide resin, after baking and hot pressing.
It has high mechanical and dielectric properties, good moisture resistance and processibility, and the heat resistance grade is H.
Suitable for insulating structural parts of high temperature resistant electrical appliances, such as motor slot wedges, gaskets and outlet plates, dry-type transformer stays, gaskets and wiring boards, etc.
