    Properties:Yellow or brown powder, specific gravity of 1.44 was dissolved in tetrahydrofuran and heated acetone, insoluble in petroleum ether, chloroform, benzene and water.
    Application: As a function of rubber chemicals,It can be for the curing agent , used for peroxide curing agent and be used as anti-scorching agent and tackifier in rubber processing. Both for general-purpose rubber, also applies to special rubber and rubber system. In natural rubber, with sulfur coordination to prevent reversion to improve the heat resistance, reduce heat, anti-aging, improve adhesion of the rubber and tire cord and the vulcanized rubber modulus. Shoulder for load tire rubber, rubber buffer layer, solve the problem of bias truck tire shoulder separation can also be used for large-size thick natural rubber products and various rubber sundries. PDM can be used as auxiliary curing agent, can significantly improve the correlation performance, increase heat resistance, suitable for high temperature curing system, reducing the compression is very obviousbut also reduce the amount of peroxide, preventing the processing of rubber in the focus burning, improve tire cord and rubber and metal bond strength. PDM is a non-sulfur vulcanizing agent for rubber cable, it can replace thiazoles, thiuram and all sulfur vulcanizing agent, solution of copper wire and copper electrical generation due to exposure to sulfur vulcanizing agent black copper sulfide contamination problems. As scorch agent for the 0.5-1.0 copies, as curing agent for the 2-3, to improve the compressive deformation of 1.5 copies, improve the adhesive strength of 0.5-5.0 copies.
    Packaging:Kraft paper bag or cardboard barrels. 25kg/bag(barrel)
    Storage:The product should be stored in the dry and cooling place with good ventilated, avoiding exposure of the packaged products to direct sunlight.
    Note:This product is oil based on user needs, treatment or granulation.
