N, N '- 4, 4' - diphenylmethane double maleic imide (hereinafter referred to as BMI, namely double horse) is a bifunctional
versatile organic compounds, the height of the double bond electrophilic make it easy and a variety of nucleophilic reagent
reaction, because of its 5 yuan heterocyclic structure, determines the characteristic of heat resistance, so it can be used as the
main monomer, synthesis of double horse polyimide resin, with a final composite plate, thin film, molding powder, adhesive agent,
coating and other forms are widely used in aerospace, aviation, electronics, insulation materials, grinding wheel, etc. It can
also be used as plastic modification liquid and rubber vulcanization agent. The 570F powder mica belt made with double horse,
epoxy, wood oil and so on is the special product of my static electrician material, with the high capacity of the electric appliance.
