Product Description

BMI is widely used in aviation, aerospace, electric power, electronics, computers, communications, automobiles, railroads, construction and other industrial fields as a more ideal resin matrix for manufacturing heat-resistant structural materials, Class H or Class F electrical insulation materials.


1. motor insulating materials High temperature resistant impregnating varnish (solvent and solvent-free), wire enamel, laminate, weftless tape, mica tape, electronic copper-clad plate, molded plastic, epoxy-modified F~H-grade powder coatings, casting parts, etc;

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

3 engineering plastics such as polypropylene PP, nylon PA, ABS, APC, PVC, PBT, EPDM, PMMA and other materials enhancement modifier (such as polypropylene fiberglass enhancement modification by adding <1% of the BMI-01, you can make the mechanical strength and Martin heat-resistant doubled, the effect is significant), but also for the new type of rubber vulcanizing agent, etc.;

4. abrasion-resistant materials Diamond grinding wheels, heavy-duty grinding wheels, brake pads, high-temperature bearing adhesives, magnetic materials, etc.
