Sulfur vulcanization a substantial fraction of natural and synthetic rubber. Reclaimed rubber has altered properties and is unsuitable for use in many products, including tires. Tires and other vulcanized products are potentially amenable to devulcanization, but this technology has not produced material that can supplant unvulcanized materials. The main problem is that the carbon-sulfur linkages are not readily broken, without the input of costly reagents and heat. Thus, more than half of scrap rubber is simply burned for fuel. Although polymeric sulfur is unstable and decomposes back to its monomer, it is possible to create stable polymers consisting mostly of sulfur via
Union Sulphur Company Union Sulphur Company The Union Sulphur Company was an American sulfur mining corporation founded in 1896 by the famous inventor Herman Frasch. It utilized the Frasch Process to extract previously inaccessible sulfur deposits located beneath swampland in Louisiana. The Union Sulphur Company dominated the world sulfur market until its patents expired in 1908. Its success led to the development of the present-day city of Sulphur, Louisiana. After its sulfur patents expired, the company transitioned into oil and natural gas production and was renamed the Union Sulphur & Oil Company and later the Union Oil & Gas Corporation.
