3. Product Application

BMI, as a kind of ideal resin matrix for the manufacture of heat-resistant structural materials, H or F class electrical insulation materials, is widely used in aviation, aerospace, power, electronics, computer, communication, automobile, railway, construction and other industrial fields.

1. High temperature resistant impregnating paint (solvent-based and non-solvent-based), enamelled wire paint, laminate, weft free strip, mica strip, electronic copper clad plate, molded plastics, epoxy modified F~H grade powder coating, casting parts, etc.;

2. Advanced composite matrix resin aerospace, aviation structural materials, carbon fiber high temperature resistant structural parts, high-grade printed circuit boards and other functional materials;

3. Engineering plastics such as polypropylene PP, nylon PA, ABS, APC, PVC, PBT, EPDM, PMMA and other materials enhancement modifier (such as in polypropylene glass fiber enhancement modification by adding < 1% BMI-01, can make the mechanical strength and Martin heat resistance doubled, the effect is significant), can also be used for TPV crosslinking agent, New rubber vulcanizing agent;

4. Wear-resistant diamond grinding wheel, heavy load grinding wheel, brake pad, high temperature bearing adhesive, magnetic materials, etc.
