Under the heat, light or oxygen, organic compounds, chemical bonds of organic molecules break down, generating reactive free radicals and hydrogen peroxide. These radicals can trigger a series of free radical chain reaction, which leads to the structural and properties of organic compounds.
Antioxidants in plastics can remove the free radicals produced by block chain reaction. Delay or inhibit the oxidation of the polymer, thereby preventing the aging of the polymer and prolonging the service life thereof.
Best antioxidant mainly inlude antioxidant 1010,antioxidant 168,antioxidant 1076,antioxidant BHT Antioxidants mainly used on plastics and rubber.
