widely used vulcanization of rubber in singapore
Sulfur vulcanization
Sulfur vulcanization. The term vulcanization is derived from Vulcan, the Roman god of fire. Hard vulcanized rubber is sometimes sold under the brand name Ebonite or the genericized former brand term vulcanite, and is used in making articles such as clarinet and saxophone mouth pieces, bowling balls, and ice hockey pucks .

Accelerated Sulfur Vulcanization
In other words, accelerators markedly reduce the time needed for vulcanization and allow for vulcanization at lower temperature and sulfur content. They also improve the scorch safety (premature cure) and the tendency of sulfur blooming to the surface of the rubber good. The most widely used (primary) vulcanization accelerators are thiazoles.

Vulcanization - an overview | ScienceDirect Topics
Rhombic sulfur, a ring of eight sulfur atoms, is soluble in rubber and the form normally used for vulcanization. About 1 to 3 phr (parts per 100 parts of rubber elastomer) of sulfur are used for most rubber products. Vulcanization by sulfur alone is believed to be primarily via a thermally induced free-radical reaction.

18 Different Types of Rubber (Plus Essential Facts)
Vulcanized rubber is less sticky and has great mechanical properties. It also comes in various hardness levels, which vary according to the amount of Sulphur used during the manufacturing process. A compound containing five percent Sulphur can be used for tire rubber, while one made with 25% Sulphur or more can make great bowling balls and even mouthpieces for saxophones.

Natural rubber
Natural rubber, also called by other names of India rubber, latex, Amazonian rubber, caucho or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water. Thailand and Indonesia are two of the leading rubber producers. Forms of polyisoprene that are used as natural rubbers are classified as elastomers.
