The quest for highly stable and durable polymers often leads formulators to explore the benefits of synergistic additive combinations. NINGBO INNO PHARMCHEM CO.,LTD. highlights a particularly effective pairing: Antioxidant 245 (CAS: 36443-68-2) with phosphite co-stabilizers. This combination capitalizes on the distinct protective mechanisms of each component to deliver enhanced thermal stability and processability to a wide range of polymers.

Antioxidant 245, a sterically hindered phenolic antioxidant, excels at scavenging free radicals, which are primary drivers of polymer degradation. It provides robust protection against thermo-oxidative breakdown, ensuring that materials maintain their mechanical properties and appearance over time. However, its effectiveness can be further amplified when used in conjunction with secondary antioxidants, such as phosphites.

Phosphites, like those often paired with Antioxidant 245, function differently. They are adept at decomposing hydroperoxides, which are intermediate products in the oxidation process. By breaking down these hydroperoxides into stable compounds, phosphites prevent them from initiating further radical formation. This dual action – radical scavenging by the phenolic antioxidant and hydroperoxide decomposition by the phosphite – creates a powerful synergistic effect.

The benefits of this synergistic approach are manifold. Polymers stabilized with this combination exhibit improved resistance to discoloration during high-temperature processing. They also benefit from enhanced long-term thermal stability, making them suitable for applications requiring sustained performance under heat. This is particularly relevant for plastics used in demanding environments where consistent properties are crucial.

Antioxidant 245's excellent compatibility with polymers such as ABS, POM, and polyurethanes, combined with the processing stability provided by phosphites, makes this pairing an ideal solution for manufacturers. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supporting the industry with innovative additive solutions that deliver tangible performance improvements. By understanding and leveraging these synergistic interactions, formulators can create plastics that not only meet but exceed performance expectations.

For any application requiring superior thermal stability and processing ease, the combination of Antioxidant 245 and phosphites is a highly recommended strategy. NINGBO INNO PHARMCHEM CO.,LTD. provides both these critical components, enabling customers to achieve optimal results in their polymer formulations.
