Vulcanization Accelerators - CROW
Vulcanization Accelerator. is a compound that increases the speed of vulcanization and that enables vulcanization to proceed at lower temperature and with greater efficiency. Vulcanization accelerators can be classified as primary and secondary accelerators. Important primary accelerators include thiazoles and sulfenamides.

Vulcanization & Accelerators
The basic accelerators such as Guanidines, Thiurams, are used as Secondary and Dithiocarbamates etc accelerators to activate the primary accelerators. The use of secondary accelerators increases the speed of vulcanization substantially but at the expense of scorch safety. The dosages of the secondary accelerators are

saturated steam at 200 psi pressure used in the continuous vulcanization of rubber-insulated wiring. Once vulcanization has started, it must proceed at a satisfactory rate to an appropriate state of cure. Finally, the accelerator must produce a vulcanizate that gives good adhesion to fibers or metal if it is a composite article,
Send InquiryAccelerant
Rubber vulcanization. It typically consists of natural rubber with a very high sulfur level (up to 8 phr), to get a relatively stiff rubber, with sulfur promoting the adhesion with the steel cord. The basis of the tire is formed by the carcass, normally a mixture of NR ( natural rubber ), SBR and BR.

Vulcanization of polychloroprene. Most conventionally used accelerators are problematic when CR rubbers are cured and the most important accelerant has been found to be ethylene thiourea (ETU), which, although being an excellent and proven accelerator for polychloroprene, has been classified as reprotoxic.
