  • How does scorch time affect vulcanization of rubber compounds?
  • Increase of the scorch time enabled safer processing of rubber compounds. Optimum vulcanization time (t 90) and cure rate index (CRI) of investigated materials significantly depended on the type of accelerator and the ratio of accelerator to sulfur.
  • How a curing system improve the quality of revulcanized rubber (vulcanized reclaimed rubber)?
  • Optimization of curing system improved processing and mechanical properties of revulcanized rubber (vulcanized reclaimed rubber) which affected on quality and price of the final product.
  • What type of accelerator is used in vulcanization?
  • Primary accelerator: this group of accelerators usually have a long burning time and are quickly cooked in the main stage of vulcanization Polymer accelerators are used to produce various types of rubber such as isoprene, styrene, butadiene and NBR. Sulfonamides are one of the most popular primary accelerators.
  • Is revulcanized reclaimed rubber suitable for application in rubber compounds?
  • The best processing and mechanical properties were estimated for revulcanized reclaimed rubber cured with conventional vulcanizing system based on TBBS and CBS accelerators. These results showed that reclaimed rubber obtained via low temperature extrusion is suitable for application in rubber compounds.
