The performance and longevity of polymer-based products are directly influenced by their resistance to degradation. Oxidation is a pervasive enemy, silently weakening materials and diminishing their aesthetic and functional qualities. In the chemical industry, specific additives are employed to combat this challenge, with Antioxidant 168 (CAS 31570-04-4) standing out as a highly effective solution. As a key phosphite processing stabilizer, it plays an indispensable role in protecting polymers from the moment they are manufactured to their final application.

The Science Behind Polymer Degradation
Polymers, particularly during thermal processing, are exposed to conditions that promote oxidation. This process involves the formation of reactive free radicals and hydroperoxides. These unstable molecules initiate a cascade of chemical reactions that can break polymer chains, alter molecular structures, and lead to a loss of physical properties such as flexibility, tensile strength, and color stability. Effectively mitigating these effects requires specialized chemical interventions.

Antioxidant 168: A Dual-Action Stabilizer
Antioxidant 168 is classified as a secondary antioxidant, primarily functioning as a hydroperoxide decomposer. It efficiently converts harmful hydroperoxides into stable, non-reactive substances, thereby halting the degradation cycle. What sets Antioxidant 168 apart is its significant synergy when combined with primary antioxidants, such as hindered phenols. This combination offers a comprehensive stabilization package: the primary antioxidant scavenges free radicals, while Antioxidant 168 neutralizes the hydroperoxides, creating a powerful defense against oxidative breakdown.

Key Features and Benefits for B2B Customers:

  • Processing Protection: The high thermal stability and low volatility of Antioxidant 168 make it ideal for protecting polymers during demanding processing stages, ensuring product quality is maintained.
  • Hydrolytic Stability: Its excellent resistance to hydrolysis ensures reliable performance, even in humid conditions or during storage where moisture contact is possible.
  • Extended Product Lifespan: By preventing oxidative degradation, it significantly contributes to the longevity and durability of the final plastic or rubber products.
  • Improved Aesthetics: It helps prevent discoloration and maintain the visual appeal of plastic components, crucial for end-user satisfaction.
  • Cost-Effectiveness: The synergistic effects and high efficacy of Antioxidant 168 mean that optimal stabilization can often be achieved with lower overall additive loadings, leading to cost savings for manufacturers.

Applications Across Industries
Antioxidant 168 is a versatile additive used in a wide array of polymers, including Polyethylene (PE), Polypropylene (PP), Polyvinyl Chloride (PVC), Polystyrene (PS), Acrylonitrile Butadiene Styrene (ABS), polycarbonates (PC), and polyamides (PA). Its applications span critical sectors such as automotive manufacturing, food and beverage packaging, electronics, textiles, and construction materials.
