  • What are the different types of vulcanization accelerators?
  • Vulcanization accelerators widely used in industry can be divided into three series: (1) guanidine based accelerators, such as diphenylguanidine (DPG); (2) dithiocarbamic acid based accelerators, such as TMTD; and (3) 2-mercaptobenzothiazole based accelerators, such as MBTS.
  • Are vulcanization accelerators catalysts?
  • Vulcanization accelerators are not catalysts because they are part of the chemical reaction. The great variety of accelerators available is a result of their different influences on the vulcanization kinetics (scorch and cure time) and on physical properties such as tensile strength, elasticity or resistance to aging.
  • What are vulcanization accelerators & activators?
  • For sulfur yellow vulcanization systems, vulcanization accelerators and activators are essential. They can reduce the amount of sulfur yellow, shorten the vulcanization time, lower the vulcanization temperature, and at the same time improve the degree of vulcanization and the physicochemical properties of the vulcanized rubber.
  • How does vulcanization affect the performance of rubber products?
  • Vulcanization, as the key step in rubber process,directly affects the processing and performance of rubber products. Compared with sulfur alone, the presence of small amounts of accelerator together with sulfur can significantly improve the properties of final vulcanisate.
