  • 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.
  • 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.
  • What is vulcanization chemistry?
  • Vulcanization is the phenomenon of formation of cross links with rubber macromolecules. These cross links can be made up of sulfur atoms or they can have some other chemical composition if other cross linking agents are used.
  • What is cold cure vulcanization method?
  • The vulcanization reactions take only a few seconds at room temperature and hence known as cold cure’ method. This method is used only for thin-walled products, proofing or for instantly cross-linking an adhesive film. Not very popular due to high toxicity of S2Cl2 solution and poor aging properties of the vulcanizate.
