Brief Introduction;Insoluble sulfur is not solible in carbon disulfide.Its name is high polymer sulfur,Is for short, which contains oil extension in different quantity.IS series of oil extension and non oil are divided.With the development of the radial truck tire industry,we have developed and manufactured highly thermal stability IS-HS series of products. Insoluble sulfur is a new rubber vulcanizing agent with which high quality of rubber products can be improved and the defects of ordinary sulfur be made up.

Benefit:

1.No blooming during the storage of rubber,keeping the performance of rubber conposition to avoid bad adhesive to rubber due to the blooming phenomenon. Pollution between rubber and mould is thus prevented.

2.No transfer in an adjacent adhesive layer.

3.A reduction in scorching in mixing and storage

4.A reduction of sulfur by shortening curing time

5.Strength of adhesion rubber to other materials.

6.IS-HS series have high heat stability and reversion resistance to ordinary sulfur at the processing temperature. Safety in rubber mixing at high temperature is increased.
