  • Which rubber accelerators are suitable for vulcanization?
  • Western Reserve Chemical offers a full range of rubber accelerators to increase the speed of the vulcanization of rubber. We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber.
  • 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 vulcanizing agent is used in rubber?
  • Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
  • 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 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.
  • Which elastomers can be vulcanized?
  • Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur. As a result, several of the same accelerators that are used with sulfur vulcanization systems can be used with zinc oxide/neoprene systems. Because there are so many, accelerators are generally classified by chemical family.
