Rubber products are subject to various aging under the practical use condition than plastics, such as heat aging, oxidative degradation, ozone cracking and fatigue failure etc.
In this article, autoxidation mechanism including chain initiation, chain propagation and chain termination, and heat oxidative degradation mechanism of various rubbers are explained from the viewpoint of chemical reaction.
