Soluble in chloroform, toluene, benzene, carbon tetrachloride. Insoluble in water and ethyl alcohol. Application: given flat, moderately fast cures in nr and sr. Also used in a wide range of general purpose rubber. Non-staining/non-discolouring in "white" socks; use as a plasticiser and/or retarder in polychloroprene rubber. Secondary acceleration is usually required for synth etic polymers. Better scorch safety than mbt. Storage: keep container tightly closed in a cool, well-ventilated place. The recommended max. Storage life is 2 years when stored under normal conditions. Packaging: 20kg bag.

It is used for natural and many synthetic rubbers.Mainly used in the manufacture of tires,hose,footwear,tape and genera industrial products. It is gray-white powder,and have three grades,qualified grade ,first grade and top grade. Its packing is 25kg plastic woven bag,paper with plastic film bag. The product could be oiled and pelleted upon customer request.

Trade name: MBTS,DM Chemical Name: Dibenzothiazole disulfide Molecular Formula: C14H8N2S4 Used as an acid accelerator currently and a medium fast primary accelerator. Imparts excellent aging properties when used both alone and in combination with DM, TMTD and many other basic accelerators for higher activity. Its accelerative temperature is low and easily be dispersed with lower pollution. Mainly used in the manufacture of tires, tubes, foot wear, rubber belts and hoses etc.
