Sulfur vulcanization Sulfur vulcanization Sulfur vulcanization or sulfur vulcanisation is a chemical process for converting natural rubber or related polymers into more durable materials by heating them with sulfur or other equivalent curatives or accelerators. Sulfur forms cross-links (bridges) between sections of polymer chain which results in increased rigidity and durability, as well as other changes in the mechanical and electronic properties of the material. A vast array of products are made with vulcanized rubber, including tires, shoe soles, hoses, and conveyor belts. The term is derived from Vulcan, the Roman god of fire. The main polymers subjected to sulfur vulcanization are
The Sulphur Institute The Sulphur Institute The Sulphur Institute, or TSI, is an international non-profit organization which acts as a global advocate for sulfur and sulfur producers. The Sulphur institute was founded in 1960, initially working with companies involved in the mining of sulfur using the Frasch process. With the increase of the Claus process for extracting sulfur from natural gas and oil, TSI's members now include multinational energy companies. The Sulphur Institute connects these sulfur producers with sulfur's largest consumer markets (fertilzers and construction materials), transporters, traders, and service providers. Today, The Sulphur Institute's member companies include a host of companies from
