Antioxidantien schützen Polyolefine vor oxidativem Abbau, indem sie Änderungen der physikalischen Eigenschaften während der thermischen Verarbeitung wie Extrusion, Compoundieren oder Spritzgießen, Blasformen und Rotationsformen minimieren. Antioxidantien verlängern die Lebensdauer von Kunststoffen unter hohen oder moderaten Temperaturbedingungen und verbessern die Witterungsbeständigkeit von UV-stabilisierten Systemen.
