  • Should rubber vulcanization accelerators be discontinued?
  • With the rapid growth in global demand for rubber products, the safety and environmental concerns of rubber vulcanization accelerators are becoming more prominent, and many countries have decreed that the production and use of certain accelerators that are carcinogenic or suspected of being carcinogenic should be discontinued.
  • 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.
  • What is the history of vulcanization accelerator?
  • The milestone in the history of vulcanization accelerator is the discovery of 2-mercaptobenzothiazole (MBT) type accelerator and its derivative hyposulfide accelerator by Bedford, Sebrell and others in 1930.
  • Do secondary accelerators increase vulcanization speed?
  • 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 generally between 10-40% of the primary accelerator. Accelerators some times are also be classified according to the chemical groups to which they belong.
