In the competitive landscape of chemical manufacturing, delivering products that enhance the performance and lifespan of materials is paramount. For industries utilizing polymers, achieving optimal performance hinges on protecting them from degradation caused by heat, light, and processing. Antioxidant 168 (CAS 31570-04-4) is a key player in this domain, functioning as a superior secondary antioxidant and processing stabilizer. As a leading supplier, we are dedicated to providing this essential component to manufacturers worldwide.

Antioxidant 168 is a phosphite antioxidant that plays a critical role in preventing oxidative degradation during the high-temperature processing of polymers. Its effectiveness lies in its ability to decompose hydroperoxides, reactive species that initiate and propagate polymer chain degradation. By neutralizing these intermediates, Antioxidant 168 effectively safeguards the polymer matrix, preventing undesirable changes in molecular weight, color, and mechanical properties.

A significant advantage of Antioxidant 168 is its remarkable hydrolytic stability. This property ensures its consistent performance even in environments where moisture is present, a common scenario in many industrial processes. Furthermore, its low volatility means that it remains in the polymer during processing, delivering continuous protection. This combination of attributes—high thermal stability and low volatility—makes it an ideal choice for manufacturers seeking to buy reliable and efficient stabilizers.

The synergistic effect of Antioxidant 168 with primary antioxidants, particularly phenolic antioxidants such as Antioxidant 1010 and 1076, is a critical aspect of its utility. While primary antioxidants are effective radical scavengers, secondary antioxidants like Antioxidant 168 complement their action by decomposing the damaging hydroperoxides. This synergistic combination offers enhanced protection against thermo-oxidative degradation, leading to improved long-term stability and extended product service life. For companies looking to optimize their product formulations, understanding and leveraging this synergy is key.

The versatility of Antioxidant 168 is evident in its broad range of applications. It is extensively used in polyolefins (polyethylene, polypropylene), engineering plastics (polyamides, polycarbonates), PVC, ABS, and various elastomers. Its ability to maintain melt stability and color integrity makes it invaluable for applications where both processing efficiency and final product aesthetics are crucial. We are proud to offer this high-performance additive, produced to meet the exacting standards of our clients.
