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 hindered phenolic, metal deactivates, amine, phosphites, thioesters and binary blends.
Hindered phenols are used as primary antioxidants. Organo-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.
