Sulfur vulcanization sulfur is not miscible in the polymer prior to vulcanization and attention is paid to prevent sulfur bloom, where it migrates to the surface of the article. Accelerators act much like catalysts allowing vulcanisation to be performed cooler yet faster and with a more efficient use of sulfur. They achieve this by reacting with and breaking the sulfur ring to form a reactive intermediate, referred to as a sulfurating agent. This in turn reacts with cure sites in the rubber to bring about vulcanization. There are two major classes of vulcanization accelerators: primary accelerators and secondary accelerators (also known as
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.
