  • 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 there an alternative to 6PPD in tires?
  • Today there is no commercially available alternative to 6PPD that both provides comparable safety and performance in motor vehicle tires and minimizes potential environmental effects. 6PPDQ Identified | USTMA requests DTSC review 6PPD in tires
  • Why is acetone better than 6PPD?
  • Acetone’s lower boiling point (56 °C) compared with 6PPD (260 °C) makes solvent recovery much less energy intensive. Although acetone can readily dissolve many classes of molecules 25, it does not degrade the cross-linked rubber phase. This is crucial for producing a 6PPD-free crumb rubber product that is safe for various applications.
  • Does acetone remove 6PPD from waste rubber?
  • A parity plot of the measured extraction efficiency versus the calculated 6PPD solubility (Fig. 2e) corroborates that solubility is a crucial determinant of the solvent’s ability to remove 6PPD from waste rubber and confirms that acetone is one of the best solvents while being inexpensive and non-toxic.
