  • 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.
  • 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.
  • 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.
  • What is vulcanization reaction of rubber?
  • Vulcanization of rubber is a very complex physical and chemical reaction process, and the cross-linked structure created after vulcanization makes the vulcanized rubber insoluble in solvents, making it difficult to understand the mechanism of vulcanization reaction of rubber by common research methods.
