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 common of which is the thermal Aging a ni a, a lum leh a oxygen. a ni.
