  • What is vulcanization accelerator?
  • Vulcanization Accelerator, Vulcanization is the conversion of a high molecular material from the plastic to the elastic state. One of the key chemical reactions in this process is that of rubber with sulfur. Sulfur vulcanization, widely used in the
  • How many accelerators are used in rubber vulcanizates?
  • r temperature and with greater efficiency. Over 150 different chemicals belonging to different classes of composition are known to function as acceler-ators for rubber vulcanizates of which around 50 accelerators are most commonly used by the Rubber Industry.There is a wide variety o
  • 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.
  • What determines vulcanization rate?
  • The accelerator determines the rate of vulcanization, whereas the accelerator to sulfur ratio dictates the efficiency of vulcanization and, in turn, the thermal stability of the resulting vulcanizate. Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur.
