Properties: light yellow powder (granules), tasteless, non-toxic, specific gravity 1.5. Soluble in chloroform, benzene, acetone, carbon disulfide, slightly soluble in gasoline and carbon tetrachloride, insoluble in water, dilute alkali.
Uses: This product is used as an auxiliary accelerator for natural rubber, synthetic rubber and latex. Because free sulfur can be decomposed when heated, it can also be used as a vulcanizing agent, and the effective sulfur content is 28% of its mass. When used as a vulcanizing agent, it is relatively safe at operating temperature, and the vulcanized rubber has excellent heat resistance and aging resistance. This product can be used as the main promoter in chlorosulfonated polyethylene rubber, styrene-butadiene rubber and butyl rubber. When used in combination with thiazole accelerators, it is especially suitable for nitrile rubber, vulcanized rubber compression set and heat resistance are excellent. When manufacturing latex sponge, it should be used in conjunction with the accelerator MZ. This product is easy to disperse in dry rubber and easy to disperse in water. No pollution. Generally used in the manufacture of heat-resistant products, cables, etc.
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.
