Product Data

he density is 1.42-1.52 Soluble in ethyl acetate, ethanol, solution of NaOH and Na2C03, insoluble in benzene, water and gasoline. Good storage stability. lower explosion limit is 21g/m3


Mainly used in IR, NR, SBR, NBR, HR and EPDM system, is a major acid vulcanizing agent, with medium vulcanization speed, and other vulcanizing agents such as DM and TMTD and other acid vulcanizing agents can be used to achieve the higher activity. Its vulcanization temperature is low, easy to disperse in the rubber, non-polluting, and mainly used in the manufacture of tires, tapes, shoes and other industrial rubber products, but can not be used as food materials.


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.
