Product Data

The density is 1.5. Soluble in chloroform, benzene, acetone, CS2, partly soluble in gasoline and CCl4 insoluble in water and alkali of lower concentration

Application

It is used as an auxiliary accelerator for natural rubber, synthetic rubber and latex. It can also be used as a vulcanizing agent because free sulfur can be decomposed when heated. When used as vulcanizing agent, it is safe at operating temperature, and the vulcanized rubber has excellent heat and ageing resistance. It can be used as the main accelerator in chlorosulfonated polyethene rubber, styrene-butadiene rubber and butyl rubber. It is especially suitable for nitrile rubber when used with a thiazole accelerator, and the compression deformation and heat resistance of vulcanized rubber are excellent. It is suitable to be used with accelerator MZ when making a latex sponges. It is easy to disperse in dry rubber and water. No pollution. Generally used in the manufacture of heat-resistant products, cables, etc.

Storage

It should be stored in a cool, dry and well-ventilated place. Packaged products should be protected from direct sunlight and are valid for 2 years.
