  • Are there any new motor vehicle tires that don't contain 6PPD?
  • USTMA is not aware of any new motor vehicle tires available today that do not contain 6PPD. 6PPD-quinone, or 6PPDQ, is a recently discovered transformation product of 6PPD that may form when 6PPD reacts with oxygen or ozone under certain conditions. 6PPDQ is not used in U.S. tire manufacturing.
  • Is pyrolysis a standalone solution for 6PPD decontamination and EOL tire upcycling?
  • This indicates that pyrolysis is not a standalone solution for 6PPD decontamination and EOL tire upcycling, and solvent extraction is essential for isolating this chemical. 6PPD can be catalytically converted to value-added products, such as cyclohexylamine, using a conventional Pd/C catalyst under hydrogen pressure.
  • Can pyrolysis irradiation decontaminate crumb rubber?
  • Volumetric heating of the carbon-black-based particles indicates uniform heating during microwave irradiation. The direct pyrolysis of crumb rubber, however, is not an effective decontamination strategy as 6PPD emerges in the pyrolysis oil product. We then turn to microwave-assisted solvent extraction to isolate 6PPD from the feedstock.
