  • Can reclaimed rubber be used without auxiliary agents?
  • Sheng et al. (2019) claim that it is possible to obtain reclaimed rubber with satisfactory mechanical properties (tensile strength above 9 MPa) in a simple way without adding any auxiliary agent. Moreover, the proposed technology can be to high extent automatic.
  • 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.
  • How to optimize the efficiency of rubber accelerators?
  • Efficiency optimization of rubber accelerators involves selecting the right accelerator for the specific rubber compound and adjusting the accelerator-to-sulfur ratio. The choice of accelerator influences the rate of vulcanization and the final product’s properties.
  • Can devulcanization agents be used to reclaim rubber?
  • In many papers, devulcanization agents, which are generally organic disulfides and mercaptans are used to reclaim rubber. Based on these chemicals, many processes have been developed and subsequently patented (Bockstal et al., 2019, Wu and Xue, 2014b, Yazdani et al., 2013).
