We are specialized in insoluble sulfur with a wide range series items.
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.

Benefits:
1.No blooming during the storage of rubber, keeping the performance of rubber conposition to avoid bad adhesive
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.Heat stability and reversion resistance to ordinary sulfur at the processing temperature. Safety in rubber mixing at a high temperature is increased.

Application: Widely used in natural and synthetic ruber in manufacturing tire,rubber belt, rubber pipe and other rubber products etc.
We can sign an agreement on specification in cases the users have special requests.
