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 working with representatives in India to encourage similar growth in sulfur usage. TSI worked with the International Fertilizer Industry Association and the Fertilizer Association of India to provide activities and resources on the use of sulfur in agriculture. TSI serves as a spokesperson for the sulfur industry with its Transportation Regulations and Logistics program. "TSI monitors for proposed changes to regulations impacting transportation and handling of sulfur and sulfur compounds." Their program covers transportation by rail, road, and sea transportation on regional, national, and international levels. The Sulphur Institute holds an international symposium annually titled The Sulphur Institute's Sulphur World
