Product Data

The density is 1.70, the decomposable temperature is 300οC. Soluble in chloroform, acetone, partly soluble in benzene, ethanol, and CCl4, and insoluble in gasoline, water and ethyl acetate. Decomposition when meeting strong acid and strong alkali


High-speed vulcanization accelerator without rubber dyeing. Suitable for NR, IR, BR, SBR, NBR, EPDM and latex. When used in dry rubber, it has the same properties as MBT and has excellent resistance to scorching. Mildly active for latex systems and often used with super accelerators. High critical vulcanization temperature (138°C). Less prone to early vulcanization and wider flatness of vulcanization. Suitable for latex systems with the function of regulating system viscosity. Suitable for injection moulding and foam rubber products. Safe operation, easy dispersion, no pollution, no discolouration. Aging resistance when used with TP. Mainly used in the manufacture of tires, hoses, rubber shoes, rubber cloth and other general industrial products.


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.
