Achieving peak polymer stability requires a sophisticated approach, often involving the strategic combination of different types of antioxidants. Antioxidant 168 (CAS 31570-04-4), a highly effective phosphite ester, plays a crucial role as a secondary antioxidant, particularly when paired with primary phenolic antioxidants. As a dedicated manufacturer and supplier, we highlight the significant synergistic benefits this combination offers to industries relying on high-performance polymers.

Antioxidant 168 excels as a processing stabilizer. During the high-temperature manufacturing of plastics, polymers are susceptible to oxidative degradation, which leads to chain scission, crosslinking, and the formation of chromophores (causing yellowing). Antioxidant 168 works by decomposing hydroperoxides, thereby mitigating these degradation processes. However, its protection is most potent when working in concert with primary antioxidants, such as hindered phenols like Antioxidant 1010 or Antioxidant 1076.

Primary antioxidants function by scavenging free radicals, which are the initiators of the autoxidation chain reaction. They provide long-term thermal stability and prevent degradation during the product's service life. The synergy arises because Antioxidant 168 deals with the intermediate hydroperoxides, allowing the primary antioxidant to more efficiently handle the free radicals. This dual action significantly enhances the overall oxidative resistance and extends the lifespan of the polymer.

For procurement managers and formulation chemists, understanding this synergistic relationship is key to optimizing their material formulations. By sourcing high-quality Antioxidant 168 from a reliable manufacturer in China, you ensure consistent performance in these critical blends. We offer Antioxidant 168 with a minimum purity of 99%, providing the reliability needed for such advanced stabilization systems. The ability to buy this product at competitive prices from a direct supplier is essential for cost-effective formulation development.

When specifying your requirements, consider the typical synergistic blends that include Antioxidant 168 along with other stabilizers like Antioxidant 1010 or 1076. These combinations are widely adopted across various polymer types, including polyolefins, polycarbonates, and styrenics, to achieve superior melt stability and color fastness. Engaging with our company for your supply of Antioxidant 168 means gaining access to a product that, when correctly formulated, delivers unparalleled polymer protection.
