  • 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 are the factors affecting vulcanizate properties?
  • The degree and type of cross links are most important factors for achieving the desired vulcanizate properties. The type of cross links depends on: Cure time. Generally, high Accelerator / Sulfur ratio and longer cure time increase the number of monosulfide cross link formation at the expense of polysulfide cross links.
  • Which vulcanizing agent is used for polychloroprene?
  • Lead oxide and Red lead are used as vulcanizing agents for polychloroprene when lower absorption and higher acid resistance is desired. (The chlorides of lead are insoluble in water / acid).
