Properties: nature nontoxic, combustible, yellow powder. As with the S-isomer, said mu-sulfur, high polymerization forms were not soluble in carbon disulfide and other solvents. Mu-sulfur instability can be gradually transformed into cubic crystal-sulfur, a few weeks at room temperature 50% change, as long as 80^oCwith changes in a few minutes, this need by adding stabilizer to reduce its rate of change.

Usage:

Insoluble sulfur can be used in rubber industry as curing agents to make rubber surface spray cream, which will improve the steel-adhesive binding, because of its plastic uniform distribution, which would ensure the quality of vulcanization being as the best rubber curing agent. It is widely used in tire carcass compound, in particular meridian tires all steel, can also be used for cable, Cots, rubber products such as rubber compound.

Storage:

The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight.
