Properties: The industrial products are white or light yellow powder or granules, the specific gravity is d420=1.50, melting point is 180℃( For the industrial products, the melting point is above 162.0℃). Slightly soluble in benzene, dichloromethane, ethanol, insoluble in water, acetic ether and gasoline. The toxicity is small, and the good storage stability period is two years. It may cause explosion danger when it is in powder status, it can burn when meets with naked flame.

Application: Common use accelerator. Widely used in all kinds of rubber, and it is semi-speeding accelerator with medium safety burning performance. Use together with other accelerator, with good vulcanization, vulcanization colloidality is superior. It is mainly used to produce tires, inner tube, rubber belt, rubber shoes and other industrial products.

Packaging: 20kg plastic woven bag, paper with plastic film bag, kraft paper bag or jumbo bag.

Storage: e product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 2 years.

Note: The product could be ultra fine powder based on customer accurate requirement.
