As a procurement manager or a product formulator, selecting the right additives is critical for the success of your polymer-based products. Among the vast array of chemical auxiliaries, antioxidants are indispensable for protecting materials from degradation. Antioxidant 168, identified by its CAS number 31570-04-4, stands out as a highly effective secondary antioxidant with a wide range of applications. Understanding its properties and benefits is the first step in making an informed purchasing decision.

Antioxidant 168 is a phosphite ester that excels at decomposing hydroperoxides formed during the thermal processing of polymers. This mechanism is vital for preventing chain scission and cross-linking, which can negatively impact a polymer's molecular weight, mechanical strength, and aesthetic appearance. Its low volatility and exceptional resistance to hydrolysis make it a reliable choice for manufacturers dealing with challenging processing conditions. When you consider buying Antioxidant 168, you are investing in enhanced product stability and processing efficiency.

The versatility of Antioxidant 168 is a major draw. It is compatible with a broad spectrum of polymers, including polyethylene (PE), polypropylene (PP), ABS, polycarbonate (PC), polyamide (PA), and various elastomers. Its ability to work synergistically with primary antioxidants, such as hindered phenols, amplifies its protective capabilities. This synergistic effect allows formulators to achieve superior long-term thermal stability and processing stability, extending the lifespan and performance of finished goods. For buyers looking for a cost-effective solution, sourcing Antioxidant 168 from a Chinese supplier can offer competitive advantages without compromising on quality.

When evaluating suppliers, look for those who can provide high purity grades (often ≥99%) and reliable supply chains. The price of Antioxidant 168 can vary, but focusing on value—which includes product quality, technical support, and delivery reliability—is key. A reputable manufacturer will offer detailed specifications, safety data sheets (SDS), and potentially sample materials for testing. This due diligence ensures that the antioxidant you purchase will perform as expected in your specific applications, whether it's for durable plastics, flexible rubbers, or advanced composite materials.

In conclusion, for businesses involved in plastics manufacturing, rubber processing, or the development of specialized polymer materials, Antioxidant 168 is a critical component. Its ability to protect polymers from degradation during processing and its synergistic potential with other stabilizers make it a highly sought-after chemical auxiliary. By understanding its benefits and choosing a reputable Antioxidant 168 manufacturer, you can significantly enhance the quality, durability, and marketability of your products.
