  • Is sulfur vulcanization a catalyst?
  • One of the key chemical reactions in this process is that of rubber with sulfur. Sulfur vulcanization, widely used in the rubber industry, requires the use of vulcanization accelerators such as Vulkacit®. Vulcanization accelerators are not catalysts because they are part of the chemical reaction.
  • 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.
  • How to optimize the efficiency of rubber accelerators?
  • Efficiency optimization of rubber accelerators involves selecting the right accelerator for the specific rubber compound and adjusting the accelerator-to-sulfur ratio. The choice of accelerator influences the rate of vulcanization and the final product’s properties.
  • 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.
