Polymer Antioxidant
Polymer antioxidants can be added to improve the shelf life of the product or to improve its high-temperature stability. while adding a stability margin during thermal processing.
Antioxidant additives can be classified into amine, hindered phenolic, phosphites, thioesters, and binary AO blends.
Hindered phenols are used as primary antioxidants. Phosphites are sometimes used as secondary antioxidants. There is a synergistic effect when using different antioxidants blended together and the combination can meet heat and processing stability requirements.
