Using characteristic
The goods are under high and low temperature (-200℃ to 260℃ ),which can give the materials outstanding mechanical properties, high electrical insulation, abrasion resistance, anti-aging and anti-chemical corrosion, radiation resistant, hardly volatile in high vacuum, and excellent adhesion resistance, humidity resistance and oil-free self-lubricity, a variety of polymer materials and new rubber excellence modifiers, but also as the coupling agent and a curing agent of the other polymer compound. Good miscibility with various fillers, and with kinds of fibers have a good wettability, adhesion and covering. It is easy to machine-shaping during a specialty polymer materials, and can mould pressed, laminated, injection molding, dipping. especially in large and thick non-insulating parts of the pores.

Applications
Over the years,Bismaleimide BMI is as the manufacture of heat-resistant structural materials, the ideal resin matrix in a H grade or F grade electrical insulating materials, becoming more widely used in aviation, aerospace, electrical, electronics, computer, communication,slocomotive railway, construction and other industrial fields. :
1.Motor insulation materials Impregnated with high temperature resistant paint (solvent-based and solvent-free), wire enamels, laminate, with no latitude, mica tape, electronic CCL, molded plastic, epoxy-modified F to H level powder coatings, castings;
2. Advanced composite material matrix resin aerospace Aerospace structural materials, carbon fibers, high temperature structural parts, high-grade printed wiring board and other functional materials, etc.;
3. Engineering Plastics Polypropylene PP, nylon PA, ABS, APC, the of PVC, PBT, EPDM, of PMMA materials enhanced modifier, crosslinking agent, and a new rubber vulcanization agent;
4. Wear-resistant materials Such as diamond grinding wheel, heavy-duty wheel, brake pads, high temperature bearings binder, magnetic materials, etc.;
5. Others Fertilizer generated (ammonia) machinery and equipment without oil lubrication, dynamic static sealing materials and many other high-tech fields.
