The example of 6PPD-quinone raises a question. What is the potential for replacement of materials and chemicals in tire manufacturing?

A tire contains numerous components, which all need to function together to deliver critical safety and performance requirements to ensure that the tire performs as it should – swapping one material or chemical for another is a delicate balancing act.

However, in the case of 6PPD (and its transformation product 6PPD-quinone), action is underway at the regional level. USTMA is supporting the state of California’s Department of Toxic Substances Control (DTSC) Safer Consumer Products Regulations process to assess potential suitable alternatives to 6PPD and is also working to advance the identification and deployment of mitigation strategies.
