TRIAL PRODUCT VULKANOX 4060

INNOVATIVE TIRE ANTIDEGRADANTS

Aging processes in tires, which are caused by oxygen or heat, change the properties of the vulcanizates. Rubbers generally are subject to such changes that occur in the course of time that can lead to partial or complete destruction. Possible consequences are depolymerization, fatigue, brittleness, cracks and even disintegration. Ozone or dynamic stress (fatigue) lead to cracking on the surface of the tire. Antidegradants are chemicals which protect the vulcanizates against these damaging external influences. Depending on the chemical structure, they act against one or more of the aging processes mentioned. The major antidegradant for the tire industry is 4-N- (4-methylpentan-2-yl)-1-N-phenylbenzene-1,4-diamine (6PPD), which is sold under the LANXESS trademark Vulkanox® 4020.
