6.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 80oCwith changes in a few minutes, this need by adding stabilizer to reduce its rate of change.

7.Application: uses insoluble sulfur used rubber industries, as curing agents make rubber surface spray cream, which will improve the steel-adhesive binding, because the plastic uniform distribution, which would ensure the quality of vulcanization, is the best rubber curing agent, it is widely used tire carcass compound , in particular meridian tires all steel, can also be used for cable, Cots, rubber products such as rubber compound.

8.Packing: Polypropylene knitted bags lined with polyethylene bags.Net weight 25kg per bag.

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