Properties:
Lamellar crystal (re-crystallization in alcohol). Bitterness. Specific gravity is 1.23 and melting point is 154~156°C. Easily soluble in alcohol, ethylether, soluble in water, insoluble in carbon bisulfide. Dissolving in alkaline solution and precipitation in acid solution.
Applications:
A fast accelerator. Its critical temperature is 80°C, it must be taken of early sulfurization when it is mixed. The activation is higher when the temperature is more than 100°C. Generally, used with zinc oxide, stearic acid may join in the system or not. The product used it has the advantage of tough and tensile, but can change the color on the effect on light.in natural latex, also can be used oelatime capsule, tyre bag, carbin, etc. The use level of it is 3.5-4 matching with 2.0-3.5 Sulfur.
Packing:
Coextruded pager bags lined with polyethylene bags. Net weight 25 kg per bag.
