Vulcanization Vulcanization Vulcanization (British: vulcanisation) is a chemical process used to harden rubber. Vulcanization traditionally referred to the treatment of natural rubber with sulfur and this remains the most common example, however the term has also grown to include the hardening of other (synthetic) rubbers via various means. Examples include silicone rubber via room temperature vulcanizing and chloroprene rubber (neoprene) using metal oxides. Vulcanisation can therefore be defined as the curing of elastomers; with the terms 'vulcanization' and 'curing' sometimes used interchangeably in this context. It works by forming cross-links between sections of polymer chain which results in increased rigidity and
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
