  • 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°C with changes in a few minutes, this need by adding stabilizer to reduce its rate of change.
  • Application: Insoluble sulfur is 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 in tire carcass
    compound, in particular meridian tires all steel, also can be used for cable, cots, rubber products such as
    rubber compound. HD OT20 is mainly used in all steel radial tire, and HS OT20 is mainly used in half
    steel radial tire and bias tire.
  • Packing: In 25kgs bag.
  • Storage: Keep container tightly closed in a cool, dry, and well-ventilated place not more than 40°C,
    avoiding fire, heat, moisture and pressure agglomeration. And it can not be mixed with alkaline amines.
