  • What are vulcanization accelerators?
  • Vulcanization accelerator also decreases the amount of sulfur needed to cross-link the polydiene, which improves the aging properties of the vulcanized rubber. The vulcanization accelerators can be further classified as primary and secondary accelerators. Some representative examples of primary accelerators include thiazoles and sulfenamides.
  • What is vulkacit cz/c?
  • Vulkacit® CZ/C by Lanxess is n-cyclohexyl-2-benzothiazolesulfenamide-based vulcanization accelerator. It is a fast but very safe accelerator providing a steep slope on the rheometer curve. It also acts as anti-corrosion agent in boilers.
  • 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.
  • 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.
  • 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.
  • Why are accelerators used in vulcanizing elastomers?
  • Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. The selection of an accelerator will depend on the specific vulcanizing system and curing properties.
