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
Texas Gulf Sulfur Company by the Frasch Process to that date. The company entered the Mexican market in 1949, with its subsidiary Cia. Exploradora del Istmo, S.A. Headquarters were established in Coatzacoalcos in 1950, and production from their Nopalapa plant commenced in 1957. By 1958, Texas Gulf had produced 69,490,00 tons of sulfur, which was 53.7 percent of the total Frasch sulphur production from 1895 through 1957. In April 1972, the company became TexasGulf. In 1981 the company was acquired by Elf Aquitaine. Texas Gulf Sulfur Company The Texas Gulf Sulphur Company was one of the largest sulfur mining companies in the world from
