    Properties: Nontoxic, combustible, yellow powder. As with the S-isomer, said mu-sulfur, high polymerization forms, 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℃with changes in a few minutes, this need by adding stabilizer to reduce its rate of change.
    Application: Insoluble sulfur is mainly used in 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.
    Packing: Polypropylene knitted bags lined with polyethylene bags.Net weight 25kg per bag.
    Storage:The product should be stored in the dry and cooling place with good ventilation.The packaged product should avoid exposure to direct sunlight.
