Rubber Vulcanising Agent Insoluble Sulfur
| insoluble Sulfur | | | Chemical Name: polymer sulfur | | Molecular Formula: Su | | CAS NO. : 9035-99-8 | | Executive standard:GB/T18952-2003 | | Specification: | | | Index | | Item | | Oil-extended Type | | Non-oil-extended Type | | IS 60 | IS 90 | IS70-20 | IS60-33 | IS60-10 | IS60-05 | | Appearance | Yellow powder | Yellow andnon-risiing powder | | (Visual inspection) | | Element SulfurContent,% ≥ | 99.5 | 79 | 66 | 89 | 94 | | Insoluble Sulfur Content,% ≥ | 60 | 90 | 70 | 60 | | Oil Content,% | | 19 | 32 | 9 | 4 | | ～21.00 | ～34.00 | ～11.00 | ～6.00 | | Acidity(H2SO4),% ≤ | 0.05 | | Loss ondrying(60oC),% ≤ | 0.5 | | Ash, % ≤ | 0.3 | | Residues on 150μmsieve, %≤ | 0.3 | | 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. |
