Description: yellow or brown powder, specific weight 1.44 soluble in tetrahydrofuran and hot acetone. Insoluble in petroleum ether, chloroform, benzene and water.The melting point is above 195℃.

Application: PDM is a functional rubber additive, which can be used as vulcanizing agent, vulcanizing agent for peroxide system, anti-coke agent and viscosity increasing agent in rubber processing.In natural rubber, with sulfur, can prevent vulcanization back to original, improve heat resistance, reduce heat generation, aging resistance, improve rubber and cord adhesion and vulcanization modulus.Used for loading tire shoulder rubber, buffer layer and other rubber, can solve the problem of oblique load tire shoulder empty, also can be used for natural rafter rubber products and various rubber miscellaneous.PDM can also be used as an auxiliary vulcanizing agent, which can significantly improve the correlation performance, improve the heat resistance, apply to high temperature vulcanizing system, reduce the compression permanent deformation is very obvious, can also reduce the amount of peroxide, prevent the burning of rubber in the process of processing, improve the adhesive strength of rubber, cord and metal.PDM is a sulfur free vulcanizing agent, used in cable rubber, it can replace thiazole class, chulam and other containing sulfur vulcanizing agent, solve the copper wire and copper electrical appliances because of contact with containing vulcanizing agent to generate copper sulfide pollution black problem.As anti-coke agent for 0.5-1.0 minutes, as vulcanizing agent for 2-3 parts, improve compression deformation for 1.5 parts, improve bonding strength for 0.5-5.0 parts.

Packaging: 20kg woven plastic bag, paper - plastic composite bag, kraft paper bag.

Storage: store in a cool dry place with good ventilation.Packaged products should avoid direct sunlight.

Description: this product can be oil treatment or granulation according to the needs of users.
