Sulfur vulcanization in the processing and compounding of rubber by Hancock and his colleagues led to a more reliable process. Around 1900, disulfiram was introduced as a vulcanizing agent, and became widely used. In 1905 George Oenslager discovered that a derivative of aniline called thiocarbanilide accelerated the reaction of sulfur with rubber, leading to shorter cure times and reducing energy consumption. This breakthrough was almost as fundamental to the rubber industry as Goodyear's sulfur cure. Accelerators made the cure process faster, improved the reliability of the process and enabled vulcanization to be applied to synthetic polymers. One year after his discovery, Oenslager
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
