Engineering plastics, such as Polycarbonate (PC), Polyamides (PA), and Acrylonitrile Butadiene Styrene (ABS), are prized for their superior mechanical properties, thermal resistance, and dimensional stability. These advanced materials are critical in demanding applications across automotive, electronics, and aerospace industries. However, their inherent processing temperatures can accelerate degradation, necessitating the use of high-performance stabilizers. Antioxidant 168 (CAS 31570-04-4) is a key phosphite ester antioxidant that plays a vital role in preserving the integrity of these materials. As a dedicated manufacturer and supplier in China, we provide the high-purity grade (≥99%) essential for optimizing these sophisticated polymer systems.

Antioxidant 168 functions as a secondary antioxidant, effectively neutralizing hydroperoxides that form during the melt processing of engineering plastics. These hydroperoxides can initiate chain scission or cross-linking, negatively impacting the strength, clarity, and color of the final product. By decomposing these harmful intermediates, Antioxidant 168 shields the polymer matrix from thermal-induced degradation, ensuring that critical properties like impact strength and tensile strength are maintained. Its low volatility and excellent hydrolytic stability are particularly advantageous in these demanding applications.

The synergistic relationship between Antioxidant 168 and primary antioxidants is crucial for maximizing the lifespan and performance of engineering plastics. This combination offers enhanced protection against thermo-oxidative degradation, a significant factor for materials exposed to prolonged heat or stress. For procurement professionals looking to buy Antioxidant 168, partnering with a reliable China-based manufacturer like us ensures competitive pricing and consistent product quality, which is vital for precise formulation.

Incorporating Antioxidant 168 into PC, PA, ABS, and other engineering plastics helps prevent discoloration and maintain critical physical properties, thereby enhancing the overall durability and aesthetic appeal of components. Whether used in electrical connectors, automotive housings, or optical lenses, the stability provided by Antioxidant 168 is indispensable. Our commitment as a manufacturer is to provide the technical data and product consistency that R&D scientists and formulation chemists require for success.
