6PPD Chemical

Detailed Description

This is the tire chemical 6PPD. 6PPD is a common rubber antiozonant found in vehicle tires. It is mobile within the rubber and slowly migrates to the surface via blooming. On the surface it forms a "scavenger-protective film" that reacts with the ozone more quickly than the ozone can react with the rubber. 6PPD-quinone is of environmental concern because it is toxic to coho salmon, killing them before they spawn in freshwater streams.
