Application of N,N'-(4,4' DIPHENYLMETHANE)BISMALEIMIDE manufactured by Yangchen Tech

 

BMI application areas known as the high temperature of the universal plastic polyamine - bismaleimide is also increasingly widely used in many areas of high and new technology, mainly:

1. Motor insulation materials

High-temperature impregnation paint (solvent and solvent-free), enameled wire paint, laminates, weftless tape, mica tape, electronic copper-clad plate, moulded plastics, epoxy-modified F ~ H-class powder coating, casting parts, and so on;

2.Advanced composite material matrix resin 

Aerospace, aviation structural materials, carbon fibre 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 glass fibre enhancement modification by adding <1% of BMI-01, you can make the mechanical strength and martin heat-resistant doubled, the effect is significant), but also can be used for the new type of rubber vulcanising agent;

4.Wear-resistant materials

Diamond grinding wheels, heavy-duty grinding wheels, brake pads, high-temperature bearing adhesives, magnetic materials and so on;

5.Others 

Oil-free lubrication of fertiliser-generating (synthetic ammonia) machinery and equipment, dynamic and static sealing materials, and many other high-tech fields. 

 

BMI  manufactured by Yangchen Tech as a heat-resistant structural materials, H-class or F-class electrical insulation materials, a more ideal resin matrix, widely used in aviation, aerospace, electric power, electronics, computers, communications, automobiles, railways, construction and other industrial fields.
