  • 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 are accelerators used for?
  • Accelerators are materials that are added in small amounts to speed up the curing of adhesives. The first accelerators were used in the 19th century. In that period, mostly oxides and hydroxides of inorganic compounds like lead, zinc, magnesium and calcium were brought to use. These days organic compounds are majorly used as accelerators.
