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.

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.

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, avoiding exposure of the packaged product to direct sunlight.

1. Insoluble sulfur exists in rubber in a dispersive state.
It can prevent the booming of rubber, having a better viscosity,
and at the same time can ensure the outer appearance of the products with light color.

2. Insoluble sulfur can disperse uniformly in rubber,
so it can prevent the conglomeration of sulfur,
and reduce the tendency of being scorched during store.

3. Insoluble sulfur can prevent the blooming of rubber during its store.
It make it possible to keep rubber's characteristics uniform,
overcoming the defects of bad viscosity resulted from blooming,
avoiding the pollution of products as well as moulds
and cut down the gelatinizing step specially appended for preventing blooming.

4. No migration in adjacent layers of rubber.
The migration speed of common sulfur is very high especially in butyl rubber,
and with the incorporation of insoluble sulfur, such phenomena can be avoided.

5. Shorten the vulcanization time.
When reaching the temperature for vulcanization,insoluble sulfur will go through a stage of activation,
that is to say, a chain de-polymerization, which can quicken the vulcanization speed,
reducing the amount of sulfur used, improving the aging characteristic of products.

Therefore, due to its non-blooming characteristic,
insoluble sulfur is widely used in the manufacture of radial rubber and other synthetic rubber products,
also in the light-colored rubber products in which common sulfur is incorporated in high proportion.
