Irgafos® comprises a range of secondary antioxidants for use in organic substrates such as plastics, synthetic fibers and elastomers. It ensures thermal protection and long-term durability as well as the integrity of polymer properties during processing. Irgafos® 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 degradation and extending the performance of the primary antioxidant. Irgafos® branded process stabilizers are available in all regions of the world offering the polymer value chain the required stabilization, manufacturing flexibility and supply security.
