Insoluble Sulfur

Insoluble sulfur, also known as polymeric sulfur, is a type of sulfur polymer with high thermal stability and low volatility. It is widely used in the rubber industry as a vulcanizing agent to improve the processing and mechanical properties of rubber products.

The primary use of insoluble sulfur is in the rubber industry, where it is added to rubber compounds during the mixing process to promote crosslinking between rubber molecules. This process improves the mechanical properties of rubber products, including their elasticity, strength, and resistance to heat, aging, and abrasion. Insoluble sulfur is particularly useful in the production of high-performance tires, belts, hoses, and other rubber products.
