People will get old and rubber will age. After the rubber products are used for a long time, some will become soft and sticky, and some will harden and become brittle. In this case, the original elasticity and strength of the rubber are remarkably lowered, and cracking, chalking, discoloration, and mildew are also caused. Aging is the result of changes in the rubber structure under the influence of various external factors, the most Communi cuius est scelerisque senescit calor et oxygeni {{III}}

Increasing the temperature also causes thermal cracking or thermal crosslinking of the rubber, but the basic effect of heat is activation. Increasing the rate of oxygen diffusion and activating the oxidation reaction to accelerate the oxidation reaction rate of the rubber is a ubiquitous phenomenon of thermal oxygen aging.
