  • 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.
  • 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.
  • What vulcanization system is used for natural rubber?
  • Both discovered the use of Sulfur and White Lead as a vulcanization system for Natural Rubber. This discovery was a major technological breakthrough for the advancement of the world economy. Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process.
  • What is a vulcanization system?
  • A vulcanization system not requiring free or donated sulfur. (These are based on metal oxides, organic peroxides etc.) Para Benzoquinonedioxime and dibenzoyl quinine dioxime can cure many rubbers through their free radical reactions.
  • 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).
  • Why do vulcanizates have high moduli?
  • It is found that as the concentration of DCBS or DBBS increases, the modulus values also increase for both the single and binary accelerator systems. As compared to the vulcanizates prepared using single accelerator, the vulcanizates prepared by incorporating the binary accelerators show high moduli.
