Rubber, plastic and the products in the long-term storage and use, due to heat, oxygen, ozone, variable valence metal ions, mechanical stress, light, effects of high-energy radiation, and other chemical substances and mold erosion, will gradually sticky , hard brittle or cracking. This physical and mechanical properties decrease with time, a phenomenon called the elasticity of aging. To do this, add some chemicals in rubber, plastic and their products to enhance its ability to resist all kinds of destructive effects of the above, the delay or inhibit the aging process, thereby extending shelf life and the life of rubber, plastic and its products, such substances called antioxidants. Antioxidant comprising: the effects of different drugs of anti-oxidants, anti-UV agents, polyvalent metal ions becomes inhibitors, anti-ozone agents, stabilizing agents such as wax, wherein the anti-oxidant and anti-oxidant into a main and auxiliary antioxidant. Since the protective effect of each antioxidant has its limitations, and rubber, plastic and products in actual use, the aging factor very large variety of complex, single antioxidant protection is difficult to meet the requirements of various products, so the actual use of general are two or more of the antioxidant and can bring to bear with good protection performance.
