Sulfur vulcanization are merely the additives used for vulcanisation and that other compounds may also be added to the rubber such as fillers or polymer stabilizers. Ordinary sulfur (octasulfur) is rarely used despite its low cost. Because of the low melting point of S vs the cure temperatures, attempted vulcanization with ordinary results in sulfur bloom. Instead, various forms of polymeric sulfur are used instead. It is also possible to replace sulfur with other sulfur-donating compounds, for example accelerators bearing disulphide groups, in what is often termed 'efficient vulcanization' (EV). Disulfur dichloride may also be used for 'cold vulcanization'. Under normal circumstances,
The Sulphur Institute addresses environmental and safety issues surrounding the transportation, production, and storage of sulfur. The Sulphur Institute's program allows regulatory agencies and industry stakeholders to connect, exchange knowledge, and develop practices which improve the safety of the industry. The Sulphur Institute provides members, government and non-government agencies, and industry stakeholders accurate information on sulfur. TSI has served as a source of industry information for many publications including the Wall Street Journal. TSI is often quoted by publications within the industry as well. The information gathered by TSI is made available through a number of publications, webinars, and speaking engagements. The Sulphur
