Polycarbonate and polyester resins are valued for their excellent mechanical properties, clarity, and thermal resistance, making them indispensable in a wide array of demanding applications, from electronics and automotive to construction and optical media. However, these high-performance polymers can still be vulnerable to degradation during processing and use, particularly under thermal and oxidative stress. NINGBO INNO PHARMCHEM CO.,LTD provides advanced solutions to mitigate these risks, with our Antioxidant Blend 215 offering critical protection to enhance their stability, processability, and longevity.

Polycarbonate (PC) is known for its impact resistance and dimensional stability, but it can be susceptible to degradation at elevated processing temperatures. Thermal stress can lead to chain scission, reducing molecular weight and consequently, impacting its toughness and clarity. Furthermore, oxidative byproducts can cause yellowing, compromising its optical properties. Polyesters, such as PET (Polyethylene Terephthalate) and PBT (Polybutylene Terephthalate), also require stabilization to maintain their strength, thermal resistance, and aesthetic qualities when subjected to processing heat and environmental factors.

Antioxidant Blend 215 is specifically engineered to provide comprehensive protection for these sensitive polymers. It is a synergistic formulation that combines a hindered phenolic antioxidant with a phosphite antioxidant. The hindered phenolic component effectively scavenges free radicals, which are the primary initiators of thermal oxidation. This prevents the rapid breakdown of polymer chains during processing. The phosphite component complements this by decomposing hydroperoxides, intermediate products of oxidation that can accelerate further degradation. This dual mechanism ensures robust protection against both initial radical formation and the subsequent propagation of oxidative damage.

The integration of Antioxidant Blend 215 into polycarbonate and polyester formulations yields significant benefits. For polycarbonate, it ensures excellent melt flow stability, allowing for consistent injection molding and extrusion processes, while simultaneously preserving its optical clarity and preventing yellowing. This is crucial for applications like lenses, glazing, and electronic housings where visual perfection is paramount. For polyesters, the blend enhances thermal stability, preventing degradation that could compromise their mechanical properties and surface finish during manufacturing and in end-use applications such as automotive components or electrical connectors. Manufacturers seeking to buy these performance-enhancing additives will find our product to be an efficient and cost-effective solution.
