Properties: white to gray-white powder (granules), relative density of 1.29. soluble in benzene, acetone, chloroform, carbon disulfide, slightly soluble in ethanol, ether, carbon tetrachloride, insoluble in water, gasoline or dilute alkali. Co-heating with water to form dimethylamine and carbon disulfide. It has a stimulating effect on the respiratory tract and skin.
Uses: used as supervulcanization accelerators in the rubber industry, often combined with thiazole accelerators, and can also be used with other accelerators as accelerators for continuous rubber materials. Because free sulfur is slowly decomposed above 100 °C, it can be used as a vulcanizing agent. The aging resistance and heat resistance of the product are excellent. Suitable for natural glue, synthetic glue. It is mainly used in the manufacture of tires, inner tubes, rubber shoes, cables and other industrial products. It is used as a fungicide and insecticide in agriculture, and can also be used as a lubricant additive.
Packing: 25kg plastic woven bags, paper-plastic composite bags, kraft paper bags.
Storage: Should be stored in a cool, dry, well-ventilated place. The packaged products should be protected from direct sunlight and have an expiration date of 2 years.
