ANOX® 20 stabilizer is a high molecular weight hindered phenolic antioxidant that provides very low volatility and excellent resistance to extraction from polymer compounds. ANOX® 20 stabilizer is particularly effective against polymer degradation during long-term aging. It is also very effective as a process stabilizer. ANOX® 20 stabilizer exhibits good resistance to discoloration at the high temperatures that are encountered in thermoplastic polymer processing.
