Achieving optimal long-term stability and processing performance in polymers often requires a multi-faceted approach, leveraging the unique strengths of different additive types. Antioxidant 168 (CAS 31570-04-4), a highly effective secondary antioxidant, plays a crucial role in this strategy, particularly when used synergistically with primary antioxidants. This combination provides a robust defense against degradation, extending the useful life and maintaining the quality of polymer products.

Primary antioxidants, such as hindered phenols like IRGANOX 1010 and 1076, or WESTCO™ AO-1010, work by scavenging free radicals that initiate oxidation. Antioxidant 168, on the other hand, functions as a hydroperoxide decomposer. By breaking down hydroperoxides into stable products, it prevents the chain reactions that regenerate free radicals. When used together, these two types of antioxidants create a powerful synergistic effect. The primary antioxidant tackles the initial free radicals, while Antioxidant 168 cleans up the hydroperoxides formed, thereby providing comprehensive protection against both processing and long-term thermal degradation.

This synergistic approach is vital for applications where polymers are subjected to high temperatures or prolonged exposure to environmental stressors. Manufacturers who choose to buy Antioxidant 168 understand that its inclusion in formulations, often as part of a carefully balanced blend, leads to superior results. Whether it's maintaining the clarity of polycarbonate, preventing chain scission in polyolefins, or preserving the mechanical properties of engineering plastics, the combined action of primary and secondary antioxidants like Antioxidant 168 is key.
