vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. the chemical reaction between sulfur and the rubber hydrocarbon occurs mainly ac (doublet the c = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). the process takes around 6 hours at 140°C

- 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 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.
- 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.
