In the pursuit of optimal polymer performance and longevity, the strategic combination of additives often yields results far greater than the sum of their individual parts. NINGBO INNO PHARMCHEM CO.,LTD. highlights the significant synergistic effects achieved when Antioxidant 245 is used in conjunction with other polymer additives, particularly thioesters and phosphites.

Antioxidant 245, a sterically hindered phenolic antioxidant, provides excellent primary protection against thermo-oxidative degradation by neutralizing free radicals. However, its performance can be significantly amplified when used as part of a carefully formulated additive package. The concept of synergy in polymer stabilization refers to the phenomenon where the combined effect of two or more additives is greater than their additive effects when used individually. This is a key reason why NINGBO INNO PHARMCHEM CO.,LTD. recommends Antioxidant 245 for complex stabilization systems.

When paired with secondary antioxidants, such as thioesters or phosphites, Antioxidant 245 demonstrates remarkable synergistic benefits. Phosphites, for instance, are highly effective hydroperoxide decomposers. They work by converting hydroperoxides – unstable byproducts of oxidation – into more stable alcohols, thereby preventing the formation of new free radicals. Thioesters offer a similar function, decomposing hydroperoxides into non-radical products. By working in tandem with Antioxidant 245, which scavenges existing radicals, these secondary antioxidants create a comprehensive defense system against polymer degradation. This dual action provides more robust and prolonged protection than either type of antioxidant could achieve alone.

The combination of Antioxidant 245 with additives like IRGANOX B215 or B225 (which are blends often containing phosphites and hindered phenols) is a well-established practice in the industry for achieving exceptional long-term thermal stability. Manufacturers can buy Antioxidant 245 from NINGBO INNO PHARMCHEM CO.,LTD. and integrate it into these synergistic blends to enhance the performance of their polymer products across various applications, including engineering plastics, styrene polymers, and polyurethanes.

The benefits of this synergistic approach include enhanced color stability, improved melt flow, and extended product lifespan, even under severe processing conditions. The reliable supply and competitive price of Antioxidant 245 from NINGBO INNO PHARMCHEM CO.,LTD. make it an accessible and highly effective component for advanced polymer stabilization strategies. By understanding and leveraging these synergistic effects, manufacturers can achieve superior material properties and competitive advantages.
