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

 

  • Motor insulation materials: high-temperature resistant impregnating varnish (solvent-based and solvent-free), wire enamel, laminates, weftless tapes, mica tapes, electronic copper-clad laminates, moulded plastics, epoxy-modified F ~ H-grade powder coatings, casting parts, etc;
  • Composite materials: matrix resin aerospace, aviation structural materials, carbon fibre high-temperature resistant structural components, printed circuit boards and other functional materials, etc.; 
  • 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 the BMI-01, you can make the mechanical strength and Martin heat-resistant doubled, the effect is obvious), but also can be used for crosslinking agent of TPV, a new type of rubber vulcanising agent, etc.;
  • Wear-resistant materials: diamond grinding wheels, heavy-duty grinding wheels, brake pads, high-temperature bearing adhesives, magnetic materials, and so on.
