Properties: white needle-like crystals. The relative density is 1.32-1.38. Soluble in benzene, carbon tetrachloride, slightly soluble in acetone, gasoline, difficult to dissolve in ethanol, ether, insoluble in water. In case of inorganic acid or inorganic alkali decomposition. Stable for storage at room temperature. Non-toxic and fishy. Touching the skin or mucous membranes can cause a strong, long-lasting sensation of spiciness.
Use: This product can be used as a vulcanizing agent and accelerator for natural rubber and synthetic rubber. The use of this product to feed the rubber material without frost, pollution, discoloration, easy to disperse. When used in effective and semi-effective vulcanization systems, the resulting vulcanized rubber has good heat resistance and aging resistance. At the vulcanization temperature, it can release active sulfur, the effective sulfur content is 27%, the operation is safe, the vulcanization rate is slow when used alone, and the sulfidation rate can be increased when combined with thiazoles, thuram and dithiocarbames. This product is especially suitable for butyl rubber, mainly used in the manufacture of tires, butyl tubes, tapes and heat-resistant rubber products, and also used as asphalt stabilizers for highways.
Packing: 25kg plastic woven bag, paper-plastic heavy bag, kraft paper bag.
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 1 years.
