| Description | rubber vulcanizing agent N,N-m-phenylene bismaleimide PDM powder or granule hva-2 casno.3006-93-7 Chemical name N,N-m-phenylene bismaleimide Molecular formula C14H8N2O4 Molecular weight 268 CAS NO. 3006-93-7 UN NO. 2811 CN NO. / EINECS. 221-112-8 Brief Introduction： PDM is Yellow or brown powder,specific gravity: 1.44. It is soluble in dioxane, 4-hydrogen furan, and hot acetone; insolvable in petroleum ether, chloroform, benzene and water. As multi-functional auxiliary agent for rubber, HVA-2 can be used as vulcanizator in rubber processing, auxiliary vulcanizator in peroxide system, vulcanization retarder and tackifier, and it can be used in universal rubber, special rubber and rubber-plastic blend. In NR, HVA-2 can prevent the revert of vulcanization, improve heat resistance, reduce heat-dissipating, and heighten aging resistance, modulus of vulcanized rubber as well as the cohesive force between rubber and tyre cord. In truck tyres, cushioning layers and such rubber, it can solve the no-filling problem of diagonal tyre edge, 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, bromized BR, AR, SR and rubber blend, it can be used as auxiliary vulcanizator to improve crosslinking effectiveness, increase heat resistance; it can also be used in high-temperature vulcanization system, to reduce compression deformation, decrease dosage of peroxide, prevent the scorching of rubber during processing, and improve the adhesive force between rubber, tyre cord and metal. Dosage: 0.5-1.0 phr as vulcanization retarder; 2-3 phr as vulcanizator; 1.5 phr for improving compression deformation; 0.5-5.0 phr for increasing adhesive strength. Specification： Item Specification Appearance Yellow or light brown powder Purity ≥99 Melting point ≥195℃ Loss on Drying ≤0.3% Ash ≤0.3% Residue on 150 um Sieve ≤0.10% Package and Storage： Kraft paper bag or cardboard barrels. 25kg/bag(barrel) The product should be stored in the dry and cooling place with good ventilated, avoiding exposure of the packaged products to direct sunlight. |
