  • 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.
  • Are rubber products vulcanized?
  • Most of the rubber-based products are vulcanized, and if the resulting three-dimensional molecular network endows rubbers with interesting thermo-mechanical properties such as high elasticity and damping, it also poses severe challenges for their reprocessing and recycling. 1.
  • How is vulcanized rubber broken down?
  • In ambient grinding, the vulcanized rubber is broken down mechanically at room temperature. The mill type and the number of grinding steps determine the final size distribution of the rubber particles. This process is generally easy and inexpensive, but the price can become very high if a very fine mesh size is required.
  • What is the role of SCCO 2 in vulcanized rubber?
  • The role of scCO 2 is not yet completely understood, but it is probably related to the fact that scCO 2 can swell vulcanized rubber. In this way, scCO 2 stretches the sulfide links, making them easier to break, and favors the penetration of devulcanizing agents, allowing devulcanization to take place in the bulk material .
  • What is devulcanized rubber?
  • Blends with thermoplastics Devulcanized rubber is an interesting blend component not only for full-elastomeric blends but also for rubber/thermoplastic compounds.
  • How can vulcanized rubber powder be recycled?
  • Another technology is the so-called High-Pressure High-Temperature Sintering (HPHTS), represented in Fig. 10, which allows the recycling of vulcanized rubber powder by applying heat and pressure .
