It is Light yellow or off-white powder, granules. The relative density is 1.42(20%), the specific gravity is 1.49±0.03, the melting point is above 180.02~181.7℃(For the industrial products, it is above 170.0℃). It will burn when meet with naked flame, the flash point is 515~520℃. Easily soluble in acetic ether, acetone, soluble in dichloromethane, diethyl ether, some other organic solvent and alkali carbonate solution. Slightly soluble in benzene. Insoluble in water and gasoline. lower explosion limit is 21g/m3. The storage stability period is two years.
For tire manufacturing, rubber belt, rubber overshoes and other industrial rubber products 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.

Natural gum and synthetic gum accelerator, can be used alone, or with sulfide carbamate, thiuram, guanidine, and other alkaline accelerator. It has rapid promoting effect on natural rubber and general sulfur yellow sulfur rubber. Its critical temperature of sulfur is low. It is easy to disperse in rubber and does not pollute. Mainly used in the manufacture of tires, tape, rubber shoes and other industrial rubber products. In IR, NR, SBR, NBR, HR and EPOM systems, it is a major acid curing agent with moderate curing rate, and can achieve higher activity when combined with other curing agents such as DM and TMTD. Its low vulcanization temperature, easy to disperse in rubber, no pollution, mainly used in the manufacture of tires, tape, rubber shoes and other industrial rubber products, but can not be used as food materials.
