  • Are vulcanization accelerators safe?
  • Vulcanization accelerators (VAs) serve as crucial additives in synthetic rubber on a global scale. Despite their widespread use, the environmental presence, distribution, and associated exposure risks of VAs remain poorly understood.
  • What is vulcanization & how does it work?
  • Vulcanization is the name originally given to the process Charles Goodyear discovered by mixing sulfur with natural rubber and subjecting it to heat to transform a plastic substance into an elastic substance. Years later it was learned that the sulfur actually crosslinks the chains of the rubber molecules.
  • 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 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.
