For businesses engaged in the manufacturing of plastics and polymer-based products, sourcing high-quality additives is a cornerstone of ensuring product performance and market competitiveness. Antioxidant 168 (CAS 31570-04-4), a vital phosphite antioxidant, plays an indispensable role in protecting polymers from degradation during processing and use. As a premier manufacturer and supplier, we aim to guide you through the procurement process, highlighting the benefits of choosing a reliable source for your needs.

Antioxidant 168 is a secondary antioxidant that functions as a highly effective processing stabilizer. Its primary function is to neutralize hydroperoxides, intermediate compounds formed during the autoxidation of polymers. These hydroperoxides are prone to breaking down into free radicals, which can initiate chain reactions that degrade the polymer, leading to reduced molecular weight, loss of mechanical properties, and discoloration. By efficiently decomposing these hydroperoxides into stable, non-radical products, Antioxidant 168 prevents this cascade of degradation, thus preserving the polymer's intended characteristics.

The key advantages that make Antioxidant 168 a preferred choice for many manufacturers include its excellent hydrolytic stability and low volatility. Unlike many other antioxidants, it maintains its efficacy even in moist conditions, ensuring consistent performance. Its low volatility ensures that the additive remains within the polymer matrix during high-temperature processing, providing sustained protection without significant loss. This attribute, combined with high thermal stability, makes it ideal for demanding applications and cost-effective bulk purchases.

Furthermore, the synergistic effect of Antioxidant 168 when paired with primary antioxidants, such as phenolic stabilizers, is a significant performance enhancer. This combination offers a robust defense against thermo-oxidative degradation, leading to extended product lifespan and improved material integrity. The ability to achieve such enhanced stability is crucial for high-performance polymer applications.

The widespread application of Antioxidant 168 across various polymer types—including polyolefins (polyethylene, polypropylene), engineering plastics (polyamides, polycarbonates), PVC, ABS, and elastomers—underscores its versatility. It is essential for manufacturers aiming for superior melt processing stability and excellent color retention in their final products.
