In the realm of polymer stabilization, achieving optimal performance often requires a multi-faceted approach. While primary antioxidants like hindered phenols are excellent at scavenging free radicals, their effectiveness can be significantly enhanced when used in conjunction with secondary antioxidants, such as phosphites. This synergistic combination provides a more robust defense against degradation, particularly during high-temperature processing and long-term service. For manufacturers seeking the highest level of polymer protection, understanding and implementing these synergistic effects with Antioxidant 1010 is key.

As a leading manufacturer and supplier of specialty chemicals from China, we offer high-purity Antioxidant 1010, known as Pentaerythritol Tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]. This hindered phenolic antioxidant acts as a primary radical scavenger, efficiently terminating the oxidative chain reactions that lead to polymer degradation. However, during high-temperature processing, polymers can generate hydroperoxides, which are unstable intermediates that can further decompose and initiate new degradation cycles.

This is where secondary antioxidants, particularly phosphites like Antioxidant 168, come into play. Phosphites function as hydroperoxide decomposers. They react with hydroperoxides, converting them into stable, non-reactive alcohols, thereby preventing them from breaking down into more damaging radicals. When Antioxidant 1010 and a phosphite antioxidant are used together, they create a powerful synergistic effect:

  • Antioxidant 1010 intercepts and neutralizes free radicals, stopping the initial stages of oxidation.
  • The phosphite antioxidant then deals with any hydroperoxides that may form, preventing them from re-initiating the degradation process.

This dual action provides superior protection compared to using either antioxidant alone. It significantly improves melt stability during processing, reduces discoloration, and enhances the long-term thermal stability of the polymer. The combination is particularly effective in polymers that are processed at high temperatures or are exposed to prolonged heat during their service life, such as polyolefins, elastomers, and engineering plastics.
