Rubber antioxidant – what factors cause rubber aging

Rubber and its products in the long-term storage and use of the process, due to heat, oxygen, ozone, variable metal ions, mechanical stress, light, high-energy radiation, and other chemical substances and mold erosion, will gradually sticky, change Hard brittle or cracked. The factors that cause the aging of rubber are: oxygen, ozone, heat, light, mechanical stress, moisture and other factors affecting the aging of rubber, rubber and other polymer materials exist in a more common phenomenon, it will make rubber Of the deterioration of the performance of rubber products affect the value and service life.
With the aging process and the development of rubber and its products will gradually reduce the performance of the complete loss of value. In order to extend the service life of rubber products, it is necessary in the rubber with some of the material can inhibit the aging process, thereby extending the rubber and its products storage period and service life. These substances are called antioxidants.
Rubber antioxidant a wide range of different roles. According to its main role can be divided into anti-thermal oxygen aging agent, anti-ozone agent, harmful metal ion inhibitors, anti-fatigue agent, UV absorbers, anti-cracking agent. However, since each protective function is often not exclusively used by certain antioxidants, most antioxidants can act on several aging factors, but only in varying degrees.
