Properties: 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.
Application: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.
Packaging: 25kg plastic woven bag, paper with plastic film bag, Kraft paper bag or jumbo bag.
Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 2 years when stored under normal conditions.
Note:The product could be ultra fine powder based on customer accurate requirement.
