  • 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 type of accelerator is used in vulcanization?
  • Primary accelerator: this group of accelerators usually have a long burning time and are quickly cooked in the main stage of vulcanization Polymer accelerators are used to produce various types of rubber such as isoprene, styrene, butadiene and NBR. Sulfonamides are one of the most popular primary accelerators.
  • 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.
  • How do I select a vulcanizing accelerator?
  • The selection of an accelerator will depend on the specific vulcanizing system and curing properties. Explore the classification of accelerators, the checklist to select the right accelerator based on the specific vulcanizing systems and curing properties.
