In the competitive landscape of polymer manufacturing, efficiency and product quality are paramount. Phosphite Antioxidant 168 (CAS 31570-04-4) is a cornerstone additive that enables manufacturers to achieve both, by providing robust protection during high-temperature processing. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in delivering this critical component to businesses seeking to optimize their production and product performance.

Understanding the Advantage: Why Phosphite Antioxidant 168?

As a secondary antioxidant, Phosphite Antioxidant 168 excels in a specific, yet vital, role: the decomposition of hydroperoxides. These unstable molecules are formed when polymers are subjected to heat and oxygen during processing. Left unchecked, they initiate chain reactions that lead to polymer degradation, manifesting as reduced molecular weight, crosslinking, discoloration, and loss of physical properties. Phosphite Antioxidant 168 effectively neutralizes these hydroperoxides, acting as a sacrificial scavenger and preventing the onset of degradation. Its unique properties include:

  • Exceptional Hydrolytic Stability: This makes it ideal for applications where moisture is a factor, ensuring consistent protection unlike less stable alternatives.
  • Low Volatility: Minimizes loss during high-temperature processing, ensuring maximum protection where it's needed most and contributing to cost savings.
  • Synergistic Performance: When used in conjunction with primary antioxidants, such as hindered phenols, it dramatically enhances the overall stabilization package, providing both processing stability and long-term heat aging resistance. This synergistic effect is key for demanding applications.
  • Color Stability: It plays a crucial role in maintaining the aesthetic integrity of polymers by preventing yellowing and discoloration during processing.

Key Industries and Applications:

The efficacy of Phosphite Antioxidant 168 has made it indispensable across a wide spectrum of polymer applications. If your business requires a reliable source to buy this material, consider its use in:

  • Polyolefins (PE, PP): Essential for applications ranging from packaging films and agricultural films to automotive parts and household goods, ensuring durability and preventing degradation during manufacturing.
  • Engineering Plastics (PA, PC, PET): Vital for materials processed at higher temperatures, where maintaining mechanical strength and dimensional stability is critical for their function.
  • Styrenics (PS, ABS): Improves the processing window and product longevity for applications in electronics, appliances, and consumer goods.
  • Adhesives and Sealants: Enhances the performance and shelf-life of formulations exposed to thermal stress.
  • Elastomers: Protects rubber compounds from oxidative breakdown, ensuring flexibility and resilience in tires, seals, and hoses.
