Full dissolved trace
properties:Appearance is light yellow crystal powder, soluble in dimethyl formamide, dimethyl acetamide, dimethyl sulfoxide with strong polar solvent, partially soluble in acetone, ethylene dichloride, cresol solvent; with many nucleophiles such as amines, phenols, hydrogen sulfide and mercaptans are addition copolymerization; can also be simultaneously with several compounds for copolymerization, blending modification.
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 area: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.

The rubber additive is a general term for various chemicals which are added to the rubber during rubber processing and which can improve the rubber processing property, improve the quality of the rubber product, and reduce the cost. Rubber additives are important raw materials for the rubber industry. Rubber additives play an important role in the improvement of processing and application properties of rubber products. The rubber additives with excellent performance can not only improve the processing performance, improve the quality of products, reduce energy consumption and production. Cost, and can prevent aging degradation and prolong the service life of rubber products. Rubber additives products comply with national industrial policies:
The "Industrial Structure Adjustment Guidance Catalogue" (National Development and Reform Commission (2011)), the eleventh item of the "encouraging category", "Petrochemical Chemicals", the 14th item "Environmental Catalysts and Auxiliaries" and the 17th item "High" Performance radial tires and supporting special materials are all related to the support of the rubber additives industry.
According to statistics, nearly 90% of the application of rubber additives is related to automobiles, and 70% of its output is used for tire production. In recent years, with the continuous growth of the global automotive industry, high-speed railway and aerospace industries, the demand for rubber products will continue to flourish, and the rubber industry will continue to develop. At the same time, the eastward shift of the international rubber industry has also provided a rapid development opportunity for China's rubber auxiliaries industry. Especially in recent years, international rubber auxiliaries production enterprises have continuously shut down their production facilities, which has made the domestic industry gain greater development. Space, China's rubber additives industry has become increasingly dominant in the global market.
