In the process of processing, storage or use of rubber blocks and rubber products, due to the influence of heat, oxygen, light, mechanical force and other factors, they will undergo physical and chemical changes, performance degradation, and even loss of use. The phenomenon is called rubber Ageing. The rubber aging process is often accompanied by some significant phenomena. For example, it can be found in the appearance that the natural rubber stored for a long time becomes soft, sticky, spots are found, and the rubber products are deformed, brittle, hard, cracked, moldy, and lose gloss. And color changes, etc. In terms of physical properties, rubber springs have changes in swelling and rheological properties. In terms of mechanical properties, tensile strength, elongation, elasticity and other indicators will decrease. Collectively referred to as the aging of rubber and rubber blocks.
