In the competitive landscape of plastics manufacturing, achieving optimal material performance and longevity is a constant pursuit. Polymers, inherently susceptible to degradation, require robust protection against oxidative processes. Antioxidant 168 (CAS 31570-04-4) stands out as a premier secondary antioxidant, playing a pivotal role in ensuring that plastic products not only withstand processing conditions but also maintain their integrity and appearance throughout their service life. For procurement managers and product developers, understanding the value proposition of this chemical is key to improving product quality and market competitiveness.

The Function of Antioxidant 168 in Plastics
Antioxidant 168, a phosphite ester, acts as a crucial processing stabilizer. Its primary mechanism involves neutralizing hydroperoxides, unstable intermediates formed during polymer oxidation. By effectively breaking down these hydroperoxides, it prevents the propagation of degradation chain reactions. This is particularly vital during the high-temperature extrusion, molding, and compounding processes where polymers are most vulnerable to thermal-oxidative breakdown. Without adequate stabilization, plastics can experience significant molecular weight changes, leading to reduced tensile strength, impact resistance, and increased brittleness.

Key Advantages for Manufacturers
Manufacturers benefit significantly from incorporating Antioxidant 168 into their formulations:

  • Superior Processing Stability: It guards polymers against degradation during heat exposure, ensuring that the material’s properties remain consistent from raw resin to finished product.
  • Enhanced Long-Term Stability: When used synergistically with primary antioxidants (like hindered phenols), Antioxidant 168 contributes to the overall long-term thermal stability of the plastic, extending its useful life.
  • Excellent Hydrolytic Resistance: This feature is critical for applications or storage conditions where moisture is present, ensuring the antioxidant remains effective.
  • Low Volatility: Minimizing loss during processing means better cost-efficiency and consistent performance.
  • Broad Compatibility: Its effectiveness across a wide range of polymers, including polyolefins (PE, PP), polyamides, polycarbonates, and ABS, makes it a versatile choice for diverse manufacturing needs.

Applications Across Industries
The impact of Antioxidant 168 is far-reaching:

  • Automotive: Enhances the durability of plastic components used in vehicle interiors and exteriors, protecting them from heat and UV exposure.
  • Packaging: Ensures the integrity and safety of food packaging materials by preventing oxidative degradation, maintaining product freshness.
  • Consumer Goods: Improves the lifespan and aesthetic appeal of household items and electronics made from plastic.
  • Construction: Contributes to the durability of plastic building materials, ensuring they withstand environmental stressors.
