For professionals in the chemical and polymer industries, understanding the nuances of material science is key to innovation and product excellence. Phosphite Antioxidant 168 (CAS 31570-04-4) stands out as a critical additive that empowers manufacturers to achieve superior performance and longevity in their polymer products. At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to supplying this vital component to businesses worldwide.

The Mechanism of Action: Combating Degradation

Polymers are susceptible to degradation when exposed to heat, oxygen, and shear forces during processing and use. This degradation can lead to undesirable changes like discoloration, loss of mechanical strength, and reduced service life. Phosphite Antioxidant 168 acts as a powerful secondary antioxidant by intercepting and neutralizing hydroperoxides, which are key intermediates in the auto-oxidation process of polymers. By effectively decomposing these harmful species into stable, non-radical products, it prevents a cascade of degradation reactions. This process is particularly crucial during high-temperature extrusion, molding, and compounding, where polymer chains are most vulnerable.

Key Advantages for Industry Professionals:

  • Excellent Thermal Stability: Phosphite Antioxidant 168 contributes significantly to the thermal stability of polymers, ensuring they withstand processing conditions without premature breakdown.
  • Low Volatility and High Hydrolytic Stability: These characteristics mean the antioxidant remains within the polymer matrix during processing and in end-use applications, providing enduring protection. This makes it an ideal choice when seeking to buy a reliable polymer additive.
  • Synergistic Power: When formulated alongside primary antioxidants, such as hindered phenols, Phosphite Antioxidant 168 exhibits synergistic effects. This means the combined protection is greater than the sum of its parts, leading to exceptional long-term thermal stabilization.
  • Color Protection: A critical benefit for many applications, this antioxidant helps prevent yellowing and other color shifts, maintaining the aesthetic appeal of the final product.

Diverse Industrial Applications:

The broad utility of Phosphite Antioxidant 168 makes it a sought-after ingredient for a wide array of polymer systems. Procurement managers often seek this compound for its application in:

  • Polyolefins: Enhancing the durability of films, fibers, and molded articles made from PE and PP.
  • Engineering Plastics: Providing essential protection for high-performance materials like PA and PC used in demanding automotive, electronic, and industrial components.
  • Styrenic Copolymers: Improving the stability and performance of ABS, SAN, and other styrenic-based materials.
  • Adhesives and Sealants: Ensuring the longevity and performance integrity of these critical bonding and sealing materials.
  • Elastomers: Protecting synthetic rubbers from oxidative degradation, maintaining flexibility and resilience.
