Characters
•AO-210 is a highly efficient phosphite antioxidant, not only for hydrogen peroxide decomposition capacity is high, also can be restored by oxidation of hindered phenolic antioxidants.The role of complement can achieve the ideal effect when used together. This product has high molecular weight, good resistance to precipitate.
•By being used with hindered phenolic antioxidant, this product can be widely used in polyolefin, polyester, nylon, etc. It can increase material heat resistance, color stability in the process, and has a long-term thermal stability.
• Especially it has a unique effect on the anti-yellowing of polyester material
