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
The Sulphur Institute addresses environmental and safety issues surrounding the transportation, production, and storage of sulfur. The Sulphur Institute's program allows regulatory agencies and industry stakeholders to connect, exchange knowledge, and develop practices which improve the safety of the industry. The Sulphur Institute provides members, government and non-government agencies, and industry stakeholders accurate information on sulfur. TSI has served as a source of industry information for many publications including the Wall Street Journal. TSI is often quoted by publications within the industry as well. The information gathered by TSI is made available through a number of publications, webinars, and speaking engagements. The Sulphur
