  • Is 6PPD in tires a priority product?
  • DTSC designates 6PPD in tires as a Priority Product and USTMA expands its consortium to 32 tire manufacturers from around the world to prepare a Preliminary (Stage 1) Alternatives Analysis (AA) to identify and evaluate potential alternatives to 6PPD in tires. Individual consortium members submitted the report to DTSC to meet compliance deadline.
  • 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.
  • Can 6PPD be removed from end-of-life tires?
  • We introduce a decontamination strategy that removes 6PPD from end-of-life tires before it enters the broader ecosystem. We demonstrate the catalytic upgrade of 6PPD to safe chemicals and the valorization of crumb rubber to aromatics and carbon black using microwave-assisted pyrolysis.

  • Does acetone remove 6PPD?
  • A scaled-up, continuous-flow microwave-powered extraction set-up can rapidly remove 6PPD and other additives from waste tires under acetone flow. Importantly, 6PPD was absent in the solvent-extracted crumb rubber and pyrolysis of the decontaminated crumb rubber indicates no 6PPD in the oil product.
