In the quest for optimal polymer performance and longevity, the strategic use of antioxidant systems is crucial. While primary antioxidants like hindered phenols are excellent at providing long-term thermal stability, their efficacy can be significantly amplified when paired with secondary antioxidants. Antioxidant 168 (CAS 31570-04-4), a highly effective phosphite ester, excels in this synergistic role, offering manufacturers a powerful solution for comprehensive polymer protection. As a leading B2B supplier, we are dedicated to helping our clients understand and implement these advanced stabilization strategies.

Antioxidant 168 functions as a hydroperoxide decomposer. During polymer processing and subsequent use, polymers are susceptible to oxidation, which leads to the formation of harmful hydroperoxides. These hydroperoxides can initiate chain reactions, accelerating degradation, causing discoloration, and compromising mechanical properties. Antioxidant 168 efficiently converts these hydroperoxides into stable, non-radical products, thereby preventing the propagation of oxidative damage. This action is particularly vital during high-temperature processing, where the rate of hydroperoxide formation is accelerated.

The real power of Antioxidant 168, however, lies in its synergistic compatibility with primary antioxidants. Primary antioxidants, typically hindered phenols, act as free radical scavengers, directly neutralizing the highly reactive radical species. When combined with Antioxidant 168, a two-pronged defense mechanism is established. The phosphite antioxidant addresses the hydroperoxides early in the oxidation cycle, while the primary antioxidant tackles the free radicals. This collaborative approach provides a much higher level of protection than either type of antioxidant could achieve on its own. For businesses looking to buy high-performance polymer additives that offer enhanced durability, this synergistic pairing is a key consideration.

This combined approach is widely implemented in various polymer applications, including polyolefins (PE, PP), engineering plastics like polycarbonate (PC) and polyamide (PA), and styrenic copolymers. The result is improved melt processing stability, better color retention, and significantly extended service life for the final products. Manufacturers who prioritize product quality and seek to reduce warranty claims will find immense value in sourcing reliable, high-purity Antioxidant 168 and complementary primary antioxidants from a trusted supplier.
