Polymers are susceptible to degradation from multiple environmental factors, including UV radiation and oxidation. While UV stabilizers like UV Stabilizer 622 are designed to combat photodegradation, the inclusion of antioxidants is crucial for comprehensive protection. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of synergistic combinations to achieve maximum polymer longevity.

UV radiation can initiate degradation by breaking polymer chains, creating free radicals. Hindered Amine Light Stabilizers (HALS), such as UV Stabilizer 622, are highly effective at neutralizing these free radicals, thereby halting the degradation process. However, polymers are also subject to oxidation, a process driven by heat and oxygen exposure, which can also lead to chain scission and loss of mechanical properties. Antioxidants are specifically designed to inhibit or slow down these oxidative processes.

The synergy between UV stabilizers and antioxidants is well-documented. Antioxidants, often phenolic or phosphite-based, work by interrupting the oxidation cycle, typically by scavenging peroxy radicals or decomposing hydroperoxides. When used in conjunction with HALS like UV Stabilizer 622, a more robust protective system emerges. The HALS shield the polymer from UV-induced damage, while the antioxidants protect it from thermal and oxidative degradation. This dual action significantly extends the material's service life and maintains its critical properties, such as color, strength, and flexibility.

NINGBO INNO PHARMCHEM CO.,LTD. offers solutions that leverage this synergy. Formulating with both UV Stabilizer 622 and appropriate antioxidants provides a comprehensive defense mechanism against the combined threats of UV light and oxidation. This approach is particularly valuable for applications exposed to challenging environmental conditions, such as automotive components, agricultural films, and outdoor building materials. By understanding and utilizing these synergistic combinations, manufacturers can ensure their polymer products achieve superior durability and performance, meeting the demands of modern applications.
