WebIrgafos ® processing stabilizers and blends thereof are the market reference recommended to ensure processing stability (color and viscosity retention). They protect polymers from thermo-oxidative degradation during processing. As a secondary antioxidant, they react with hydroperoxides formed by auto-oxidation of polymers, preventing process induced … WebIrgafos® 168 performs best when combined with other BASF antioxidants. Blends of Irgafos® 168 with hindered phenols of the Irganox® range (Irganox B-blends) are particularly effective. The hindered phenols additionally provide storage stability and give the polymer long term protection against thermooxidative degradation.
