Styrene-Butadiene (SBR) Rubber: Uses, Structure & Material
Styrene-butadiene rubber can be vulcanized using sulfur, sulfur donor systems and peroxides. Sulfur is added in slightly smaller amounts than to natural rubber and in tire compounds. Sulfur is added in slightly smaller amounts than to natural rubber and in tire compounds.

Sulfur vulcanization
Worker placing tire in a mold before 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 sulphur, or other equivalent curatives or accelerators. Sulfur forms cross-links (bridges) between polymer chains.

Why is sulphur used for the vulcanization of rubber?
Till late 1950, only sulphur was used to vulcanize rubber compounds. Its not true that only sulphur can be used for vulcanisation. Actually, sulphur can only vulcanise unsaturated rubbers (polymer chain containing double bonds) like Natural rubber, Styrene Butadiene rubber, Nitrile Butadiene rubber, etc.
Send InquiryVulcanization
Accelerated vulcanization is carried out using various compounds that modify the kinetics of crosslinking, this mixture is often referred to as a cure package. The main polymers subjected to sulfur vulcanization are polyisoprene (natural rubber) and styrene-butadiene rubber (SBR), which are used for most street-vehicle tires. The cure package is adjusted specifically for the substrate and the application.
