  • 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 to devulcanize natural rubber and styrene/butadiene rubber vulcanizates?
  • Mechanochemical devulcanization of natural rubber (24) and styrene/butadiene rubber (25) vulcanizates was carried out using different concentrations of bis (3-triethoxysilylpropyl)tetrasulfide at ∼70 °C in an open-roll mixing mill.
  • 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 ultrasonic devulcanization?
  • Ultrasonic devulcanization Ultrasonic devulcanization is one of the most interesting and convenient devulcanization processes, as it allows a high degree of devulcanization and precise control of the properties of the devulcanizates.
