In the demanding world of polymer manufacturing, ensuring product longevity, aesthetic appeal, and consistent performance is paramount. One of the key challenges faced by formulators and manufacturers is preventing polymer degradation caused by heat, light, and oxidation during processing and throughout the product's lifespan. This is where advanced additives, such as phosphite antioxidants, play a crucial role. This article delves into the benefits and applications of these essential compounds, focusing on a prominent example: 4,4'-Isopropylidenediphenol C12-15 alcohol phosphite (CAS 96152-48-6).

The Importance of Phosphite Antioxidants in Polymers

Phosphite antioxidants, particularly secondary antioxidants, function by decomposing hydroperoxides into stable products. This process effectively interrupts the auto-oxidation chain reaction, thereby protecting polymers from degradation. Unlike primary antioxidants that scavenge free radicals, phosphites are highly effective at preventing melt degradation and discoloration during high-temperature processing. This makes them indispensable for manufacturers working with materials like PVC, polyolefins (PE, PP), and ABS.
