LANXESS has developed Vulkanox 4060, a new anti-aging agent for the tire industry. The innovative additive with the chemical name CCPD (N,N'-Dicyclohexyl-p-phenylenediamine) was designed as an alternative to 6PPD – an anti-aging agent used in nearly all tires to protect them from damage caused by oxygen and ozone. The degradation products of 6PPD, particularly 6PPD quinone, which has been linked to coho salmon die-offs in the U.S., have been the subject of criticism for some time. In environmental studies conducted to date, CCPD quinone, the corresponding transformation product of Vulkanox 4060, demonstrated no observed acute effects in coho salmon testing up to the solubility limit. With the completion of EU REACH registration, Vulkanox 4060 is now also approved for use in the European market.
