For professionals in the chemical and polymer industries, selecting the right additives is crucial for product performance and manufacturing efficiency. Phosphite Antioxidant 168 (CAS 31570-04-4) is a highly effective processing stabilizer that offers significant advantages in a wide range of polymer applications. NINGBO INNO PHARMCHEM CO.,LTD., as a leading chemical manufacturer in China, is your trusted partner for sourcing this essential compound.

Understanding the Function of Phosphite Antioxidant 168

Phosphite Antioxidant 168 is categorized as a secondary antioxidant. Its primary mechanism involves the decomposition of hydroperoxides, which are detrimental intermediates formed during the thermal processing of polymers. By neutralizing these hydroperoxides, it prevents them from initiating chain scission and crosslinking reactions that degrade polymer integrity. Its key attributes make it a preferred choice for many formulations:

  • Exceptional Processing Stability: It is vital for protecting polymers during high-temperature processing stages, ensuring minimal degradation and maintaining desired physical properties.
  • High Hydrolytic Stability: This property ensures that the antioxidant remains effective even in humid conditions, a significant advantage over less stable alternatives.
  • Low Volatility: Its low vapor pressure minimizes loss during extrusion and molding, contributing to both cost-effectiveness and consistent protection.
  • Synergistic Combinations: Phosphite Antioxidant 168 often works in synergy with primary antioxidants (like hindered phenols) to provide comprehensive protection against both processing-induced degradation and long-term thermal aging. This dual action is highly desirable for manufacturers looking to buy the best possible stabilization package.
  • Color Protection: It helps maintain the original color of the polymer, preventing yellowing and discoloration that can occur during processing.

Applications Across Diverse Sectors:

The versatility of Phosphite Antioxidant 168 makes it an indispensable additive in various polymer systems. If you are seeking to purchase this material, consider its applications in:

  • Polyolefins (PE, PP): Crucial for enhancing the durability of films, fibers, pipes, and molded articles used in packaging, construction, and automotive industries.
  • Engineering Plastics (PA, PC, PET): Provides essential protection for high-performance polymers during demanding processing conditions, vital for applications in electronics and industrial components.
  • Styrenic Polymers (PS, ABS): Improves processing stability and extends the service life of products in consumer goods, appliances, and automotive interiors.
  • Adhesives and Coatings: Contributes to the thermal stability and longevity of adhesives and coatings.
  • Elastomers: Helps prevent oxidative degradation, maintaining flexibility and performance in rubber products.
