| 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. |
| Package | 25kg kraft paper bag. |
| Storage | The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 1 years. |
