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.
