vulcanization agent an overview sciencedirect topics vulcanization agent an overview sciencedirect topics,vulcanizing the rubber with mostly used vulcanizing agent sulfur initiates the cross-linking of rubber that is not saturated [26]. however, sulfur, as a vulcanizing agent, does not proceed swiftly. when rubber and hydrocarbons make chemical reactions, this process generally involves double bonds or c c, along with it every cross-linking needs 40–55 atoms of sulfur without accelerator.

- What is accelerator in rubber vulcanization?
- An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates.
- How is rubber vulcanized?
- Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. The chemical reaction between sulfur and the Rubber Hydrocarbon occurs mainly at the C = C (double bonds) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator).
- What is the role of accelerator in vulcanization?
- Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates. Accelerators are also classified as Primary and / or Secondary accelerators based on the role they play in a given compound.
- Is vulcanizate a polysulfidic cross link?
- The combined sulfur with rubber exists predominantly in the ‘Polysulfidic cross links’ form and the amount of free sulfur and the ratio of free sulfur to accelerator varies from rubber to rubber. A fair degree of wasted sulphides and main chain modifications are present in the vulcanizate.
