In the fast-paced world of polymer manufacturing, maintaining the integrity and performance of materials throughout processing is paramount. Degradation caused by heat and oxidation can lead to significant issues, including molecular weight changes, discoloration, and a reduction in mechanical properties. This is where advanced chemical additives like Antioxidant 168 (CAS 31570-04-4) become indispensable. As a key processing stabilizer, Antioxidant 168 is engineered to combat these challenges effectively.

Antioxidant 168, known for its exceptional hydrolytic stability and low volatility, plays a dual role. Primarily, it acts as a secondary antioxidant, reacting with hydroperoxides that form during the autoxidation of polymers. This crucial reaction prevents the propagation of degradation chains, thereby shielding the polymer from heat-induced damage. Furthermore, its ability to preserve the original color of the polymer is a significant advantage in applications where aesthetics are as important as performance.

The versatility of Antioxidant 168 extends across a broad spectrum of polymers. It is highly effective in polyolefins such as polyethylene (HDPE, LLDPE) and polypropylene, as well as in olefin copolymers like ethylene-vinylacetate (EVA). Beyond polyolefins, it finds application in polycarbonates, polyamides, ABS resins, PS resins, PVC, and various engineering plastics. Its use is also prevalent in the rubber industry, where it helps maintain elasticity and resilience, and in coatings and paints to ensure long-term surface protection. For businesses looking to source reliable polymer additives, understanding the synergistic effects of Antioxidant 168 when combined with primary antioxidants, such as those from the IRGANOX range or WESTCO™ AO-168, can unlock even greater performance benefits, ensuring extended shelf life and product durability.
