What is 6PPD-quinone?
We are aware of the recent identification of 6PPD-quinone and of the preliminary studies that have investigated potential environmental impacts of this chemical. 6PPD-quinone – also known as 6PPD-Q – is a transformation product of the important tire ingredient 6PPD. 6PPD is an antioxidant and antiozonant that helps stop rubber from breaking down, which is critical for tire safety.
TIP welcomes efforts to improve scientific understanding of the potential impacts of TRWP, and following the identification of 6PPD-quinone, building on more than a decade of TIP-sponsored research into TRWP, TIP’s research plan now includes efforts to contribute to the body of scientific knowledge on this chemical.
