HVA-2 Vulcanizer (PDM)
Chemical name: N,N'-m-phenylene bismaleimide
Properties: Yellow or brown powder. Specific gravity: 1.44. It is soluble in dioxane, 4-hydrogen furan and hot acetone. insoluble in petroleum ether, chloroform, benzene and water.
Functions: As a multifunctional auxiliary agent for rubber, HVA-2 can be used as vulcanizer in rubber processing, auxiliary vulcanizer in peroxide system, vulcanization retarder and adhesive agent, and can be used in general rubber, special rubber and rubber-plastic mixture. In NR, HVA-2 can prevent re-vulcanization, improve heat resistance, reduce heat dissipation, and increase aging resistance, modulus of vulcanized rubber as well as the cohesive force between rubber and cord tire. In truck tires, shock-absorbing layers and such rubber, it can solve the problem of not filling the diagonal edge of the tire, and can be used in thick and large NR products and other rubber products. In the special rubber such as CR, CSPR, SBR, NBR, IIR, BR, bromide BR, AR, SR and compound rubber, it can be used as an auxiliary vulcanizer to improve the cross-linking efficiency, increase the heat resistance. It can also be used in high temperature vulcanization system, to reduce compression deformation, reduce peroxide dosage, prevent rubber from burning during processing, and improve the adhesive strength between rubber, tire cord and metal.
Dosage: 0.5-1.0 phr as vulcanization retarder. 2-3 phr as a vulcanizer. 1.5 phr to improve compression distortion. 0.5-5.0 phr to increase adhesive strength.
