As specialists in chemical manufacturing, we aim to provide clear, technical insights into the products that drive innovation in material science. Antioxidant 168 (CAS 31570-04-4) stands out as a pivotal additive, particularly for industries that rely on the integrity and longevity of plastic and polymer materials. For R&D scientists and formulation chemists, understanding its chemical properties and applications is key to unlocking optimal product performance.

Antioxidant 168 is classified as a phosphite ester and functions primarily as a secondary antioxidant. Unlike primary antioxidants that scavenge free radicals directly, secondary antioxidants like Antioxidant 168 work by decomposing hydroperoxides, which are formed during the oxidative degradation of polymers. This process effectively breaks the chain reaction of degradation, thereby protecting the material from heat-induced breakdown and discoloration. Its low volatility and high thermal stability make it exceptionally suitable for demanding processing conditions encountered in polymer extrusion, injection molding, and compounding.

A significant advantage of Antioxidant 168 is its remarkable synergism with primary antioxidants. When used in combination, these additives create a robust protection system, significantly extending the material's lifespan and maintaining its critical properties. This makes it a valuable component for manufacturers seeking to buy high-quality stabilizers. Our position as a leading manufacturer in China allows us to supply Antioxidant 168 with a guaranteed purity of ≥99%, ensuring consistent and reliable performance for your formulations. We offer competitive pricing for bulk purchases.

The applications for Antioxidant 168 are diverse, reflecting its broad efficacy. It is indispensable for stabilizing polyolefins (PE, PP), engineering plastics (PC, PA, ABS), PVC, and various elastomers. Its ability to prevent yellowing is particularly appreciated in applications where aesthetic appeal is crucial.
