Sulfur

Sulfur (CAS 7704-34-9), also known historically as brimstone or sulphur, is a naturally occurring non-metallic element supplied in refined form for industrial and agricultural use.

It functions as a vulcanizing agent, fungicide, and chemical intermediate across a broad range of manufacturing and crop protection applications. In rubber and tire manufacturing, it is the primary cross-linking agent.

During vulcanization, it forms the polymer bridges that give rubber its mechanical strength and elasticity. Agricultural formulators use it as a contact fungicide and acaricide in crop protection products.

These products target powdery mildew and mite infestations. In mining and metallurgy, it is a feedstock for sulfuric acid production, which drives ore leaching and metal refining operations.

Textile and leather processors use sulfur-based compounds for fiber bleaching, hide preservation, and wastewater treatment. It is available as bright yellow powder, prilled granules, and crushed lump forms.

Each form is suited to different handling and dosing requirements. Standard grades include agricultural-grade, rubber-grade, and technical-grade, with refined grades meeting pharmaceutical specifications.

Purity levels typically range from 90% agricultural grade up to 99.9%+ for refined industrial and pharmaceutical applications. This ensures high performance across diverse chemical synthesis processes.
