TRIAL PRODUCT VULKANOX 4060

Aging processes, 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 and 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 rubber article. Antidegradants such as Vulkanox® are chemicals which protect the vulcanizates against damaging external influences. Depending on the chemical structure, they act against one or more of the aging processes mentioned.
