Mechanism Of Action Of Rubber Antioxidants

The mechanism of action of rubber antioxidants is complex, involving various chemical reactions and physical processes. Some rubber antioxidants act like physical adsorbents, adsorbing contaminants such as moisture and oxygen inside the rubber, reducing the formation of free radicals and peroxides, thereby slowing down the aging process of rubber. Others act like antioxidants, directly reacting with oxygen to counteract or reduce its oxidizing effect on rubber. Furthermore, similar to catalysts, some rubber antioxidants can promote various internal reactions within rubber molecules through their own catalytic action, thereby reducing the aging rate of rubber.
