The Mechanism of Action: Combating Degradation
Polymers are susceptible to degradation when exposed to heat, oxygen, and shear forces during processing and use. This degradation can lead to undesirable changes like discoloration, loss of mechanical strength, and reduced service life. Phosphite Antioxidant 168 acts as a powerful secondary antioxidant by intercepting and neutralizing hydroperoxides, which are key intermediates in the auto-oxidation process of polymers. By effectively decomposing these harmful species into stable, non-radical products, it prevents a cascade of degradation reactions. This process is particularly crucial during high-temperature extrusion, molding, and compounding, where polymer chains are most vulnerable.
