The longevity and performance of plastic materials are critically dependent on their ability to resist degradation caused by environmental factors such as heat, oxygen, and light. Oxidation, in particular, is a pervasive threat that can lead to a loss of mechanical properties, discoloration, and ultimately, product failure. Understanding the science behind stabilization is key to developing high-performance plastics, and at NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to advancing this field with innovative solutions like Phosphite Antioxidant 168.

Phosphite Antioxidant 168, known chemically as Tris(2,4-di-tert-butylphenyl) phosphite, is a sophisticated secondary antioxidant. Its primary function is to act as a hydroperoxide decomposer. During the auto-oxidation process of polymers, hydroperoxides are formed as unstable intermediates. These hydroperoxides can decompose to generate free radicals, which then propagate the oxidation chain reaction, leading to polymer degradation. Phosphite Antioxidant 168 intervenes by reacting with these hydroperoxides, converting them into stable, non-radical products, thus effectively breaking the degradation cycle.

The effectiveness of Phosphite Antioxidant 168 stems from its excellent thermal stability and low volatility. These properties are crucial because polymers are often processed at high temperatures, where oxidation is accelerated. By remaining stable and active under these conditions, Phosphite Antioxidant 168 protects the polymer melt from thermal and oxidative breakdown, preserving its molecular structure and essential properties. Its ability to resist extraction by water further enhances its utility in applications where moisture is present.

Furthermore, Phosphite Antioxidant 168 exhibits remarkable compatibility with a wide array of polymers, including but not limited to polyolefins (polypropylene, polyethylene), ABS, polycarbonate, PVC, and polyesters. This broad compatibility allows for its widespread application across different polymer types and manufacturing processes. An added benefit is its synergistic effect when combined with primary antioxidants, such as hindered phenols. This combination provides a more robust and comprehensive defense against degradation, maximizing the overall protective capabilities of the additive package.

For manufacturers seeking to buy reliable and effective stabilizers, Phosphite Antioxidant 168 from NINGBO INNO PHARMCHEM CO.,LTD. represents a scientifically backed solution. By incorporating this advanced additive into their formulations, companies can significantly improve the processing stability and long-term durability of their plastic products.
