Chemical Name:2-Mercaptobenzothiazole Molecular Formula: C7H5NS2 Modular Weight: 167.25 CAS NO: 149-30-4 Properties: Slightly foul odor and bitter taste, nonpoisonous. Specific gravity: 1.46-1.52.Soluble in ethyl acetone, acetone, dilute solution of sodium hydroxide and sodium carbonate, ethyl alcohol. Not easily soluble in benzene. Insoluble in water and gasoline. Application: Used for NR, IR, SBR, NBR, HR and EPDM.One of the mainly used acidic accelerators currontly and a medium fast primary accelerator. Imparts excellent aging properties, when used both alone and in combination with DM,TMTD and many others, mainly basic accelerators for higher activity. But care should be taken because it has a slight tendency to scorch. Unsuitable for use in the manufacture of food contact materials. Mainly used in the manufacture of tires, tubes, footwear, rubber belts and hoses etc. 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:25kg bag.

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.
