  • 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.
  • What are the TPS of rubber antioxidants?
  • The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
  • Which rubber antioxidants are used in China?
  • Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
