  • What type of rubber is used for vulcanization?
  • Since most of the research on devulcanization has been made on waste tires, this review mainly focuses on the most widely used rubber classes for this application, i.e., natural rubber (NR) and styrene-butadiene rubber (SBR), and the most common vulcanization technique, i.e., sulfur vulcanization.
  • 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.
  • Do vulcanizing agents in dgtr help recover tensile strength?
  • Additional vulcanizing agents in dGTR helped recover tensile strength because of the more significant number of cross-links generated compared with other samples (Fig. 4 b). The tensile strength of the samples: mixtures containing dGTR (a) and containing dGTR and extra vulcanizing agents (b).
  • 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).
