Performance:White or light yellow needle-like crystals with a density of 1.32~1.38 g/cm3. Soluble in benzene, ethanol, acetone, carbon tetrachloride, slightly soluble in acetone, gasoline, insoluble in ethanol and ether, insoluble in water and aliphatic hydrocarbons. In case of inorganic acid or inorganic alkali decomposition, good storage stability at room temperature.
Use:Vulcanizing agents and vulcanizing accelerators for natural and synthetic rubber. Active sulfur can be released at vulcanization temperature, the effective sulfur content is 27%, the operation is safe, the vulcanization speed is slow when used alone, and the vulcanization speed can be improved when used together with thiazole, thiuram and dithiocarbamate. This product does not spray frost, no pollution, no discoloration, easy to disperse. Particularly suitable for butyl rubber. Mainly used in the manufacture of tires, butyl inner tube, tape and heat-resistant rubber products, but also used for highway asphalt stabilizer.
Packing:Composite paper bag, lined with plastic film bag, net weight 25kg.
Storage:Sealed and stored in a cool, dry, well-ventilated place, away from direct sunlight.
Safety and Toxicity:Please refer to the relevant product safety data (MSDS).
