In the realm of polymer science, the quest for materials that withstand the ravages of time and environmental stress is relentless. Oxidation, a pervasive threat, can degrade polymers, leading to brittleness, discoloration, and loss of mechanical integrity. While primary antioxidants are the frontline defense, neutralizing harmful free radicals, their effectiveness is often amplified by the strategic use of secondary antioxidants. At NINGBO INNO PHARMCHEM CO.,LTD., we champion a comprehensive approach to polymer stabilization, recognizing the power of synergistic blends, particularly those involving high-performance additives like Phosphite Antioxidant 168.

Primary antioxidants, typically hindered phenols or aromatic amines, function by donating a hydrogen atom to reactive free radicals, thus terminating the oxidation chain reaction. However, this process can be limited, and under certain conditions, the formation of hydroperoxides can still occur. This is where secondary antioxidants, such as Phosphite Antioxidant 168, play a crucial role. Phosphite antioxidants are renowned for their ability to decompose hydroperoxides into stable, non-radical species. This deactivation prevents the formation of new free radicals, effectively creating a multi-layered defense system against degradation.

The synergistic effect between primary and secondary antioxidants is a cornerstone of modern polymer stabilization. When used together, they offer a broader spectrum of protection than either type could provide alone. For instance, a primary antioxidant might handle the initial free radical scavenging, while Phosphite Antioxidant 168 diligently works to break down any hydroperoxides that manage to form. This combined action significantly enhances the material's resistance to thermal oxidation, a critical factor during polymer processing. The low volatility and excellent heat stability of Phosphite Antioxidant 168 ensure its persistent protection even at elevated temperatures.

The benefits of employing such synergistic systems are manifold. Manufacturers can expect improved melt stability, reduced yellowing or discoloration, and ultimately, a significant extension of the product's service life. This is particularly important for applications demanding high durability and aesthetic appeal. Phosphite Antioxidant 168's compatibility with a wide range of polymers, including polyolefins, ABS, and polyesters, makes it a versatile choice for various industries. Whether you are looking to purchase additives for the production of durable plastic components or high-performance synthetic fibers, understanding the benefits of these synergistic combinations is key.
