In the realm of polymer science and manufacturing, maintaining material integrity during processing is paramount. Oxidative degradation, a common challenge, can significantly compromise the physical and mechanical properties of plastics. This is where specialized additives like Antioxidant 168 (CAS 31570-04-4) come into play. As a leading phosphite processing stabilizer, Antioxidant 168 is indispensable for manufacturers seeking to produce high-quality, durable polymer products.

What is Antioxidant 168?
Antioxidant 168, identified by its CAS number 31570-04-4, is a chemical compound widely recognized for its excellent antioxidant properties. It falls into the category of secondary antioxidants, meaning it works by decomposing hydroperoxides, which are byproducts of polymer autoxidation. By neutralizing these hydroperoxides, Antioxidant 168 effectively prevents the chain reactions that lead to polymer degradation during high-temperature processing. This protective action is crucial for maintaining molecular weight, preventing discoloration, and preserving the intended physical characteristics of the polymer.

Key Properties and Benefits
Several attributes make Antioxidant 168 a preferred choice among polymer manufacturers and compounders:

  • Hydrolysis Resistance: Unlike many other phosphite stabilizers, Antioxidant 168 exhibits remarkable resistance to hydrolysis. This ensures its efficacy and stability even in environments where moisture exposure is a concern, making it a reliable choice for various applications.
  • Low Volatility: Its low volatility means that the additive is less likely to evaporate during the high-temperature processing of plastics. This ensures that the intended concentration remains within the polymer matrix, providing consistent protection.
  • High Thermal Stability: Antioxidant 168 demonstrates excellent thermal stability, allowing it to perform effectively under the demanding conditions of polymer processing, such as extrusion and injection molding.
  • Synergistic Effects: A significant advantage of Antioxidant 168 is its synergistic interaction with primary antioxidants, particularly hindered phenols. When used in combination, these stabilizers provide a more robust and comprehensive protection against both processing-induced degradation and long-term thermal aging. This dual action significantly enhances the overall performance and lifespan of the polymer product.

Applications in the Polymer Industry
The versatility of Antioxidant 168 allows its application across a broad spectrum of polymers and industries:

  • Polyolefins: It is extensively used in polypropylene (PP) and polyethylene (PE) to protect them from thermal oxidation during manufacturing and fabrication, thereby improving their mechanical properties and appearance.
  • Engineering Plastics: For materials like polycarbonates (PC) and polyamides (PA), Antioxidant 168 helps maintain their structural integrity and performance under high processing temperatures.
  • Rubber and Elastomers: It contributes to preserving the elasticity and durability of rubber compounds used in automotive parts, industrial components, and consumer goods.
  • Adhesives and Coatings: Antioxidant 168 enhances the stability of adhesives and coatings, ensuring their long-term performance and resistance to environmental degradation.
