  • 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.
  • 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.
  • 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.
  • Is accelerator MBTS available in a polymer bound dispersion?
  • Accelerator MBTS is also available in a polymer bound dispersion. Several polymer carriers are available. These polymeric masterbatches contain 70-80% Accelerator MBTS and are very soft for ease of incorporation. Akrochem polymer bound dispersions eliminate irritating dust, as well as other potential hazards in handling powders in the plant.
