Sulphur Mono Chloride

Rubber Vulcanization: Utilized in the "cold" vulcanization process for thin rubber goods like gloves and balloons.
Chemical Synthesis: Serves as a key intermediate in the production of sulfur dyes, herbicides, and pharmaceutical precursors.
Additives Production: Used to manufacture extreme-pressure (EP) additives for high-performance lubricants and cutting oils.

Sulphur Mono Chloride (CAS 10025-67-9) is a reactive inorganic chlorinating agent and sulfur source that appears as a yellow-red oily liquid with a sharp, suffocating odor, and it is used mainly for cold vulcanization of rubber and for synthesizing organic sulfur compounds and pharmaceutical precursors. It is a highly reactive inorganic compound that fumes in moist air and reacts violently with water. This product is a critical Chlorinating Agent and sulfur source, maintaining a high Purity of 98% . In polymer science, it acts as a cross-linking agent for specialized elastomers and synthetic resins. Its Intermediary Role is vital for the production of insecticides, dyes, and sulfur-based chemical additives.
