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,
Texas Gulf Sulfur Company Texas Gulf Sulfur Company The Texas Gulf Sulphur Company was one of the largest sulfur mining companies in the world from 1919 to 1981. The Gulf Sulphur Company was formed on December 23, 1909 by a group of investors from St. Louis and Texas. The company was formed to exploit the newly discovered sulfur deposit in the Big Hill salt dome near Matagorda, Texas, using the Frasch Process. In 1916 Bernard Baruch and J.P.
