ANOX™ 20 Granular is a high–molecular weight hindered primary phenolic antioxidant. It prevents polymer degradation during long-term aging in various polymer systems.
ANOX™ 20 Granular is a high–molecular weight hindered phenolic antioxidant that primarily functions as a polymer stabilizer and prevents degradation during storage and long-term aging. ANOX™ 20 Granular phenolic antioxidant is a high-performance stabilizer that offers outstanding resistance against discoloration while processing plastics and elastomers. ANOX™ 20 Granular provides superior protection as an antioxidant and process stabilizer for thermoplastic polymer applications.
ANOX™ 20 Granular also protects from high-temperature-induced scorch for polyols, polyurethanes, and foam formulations. As a hindered phenolic antioxidant, ANOX™ 20 Granular offers additional synergy with SI Group phosphite antioxidants, such as ALKANOX™ 240 and WESTON™ 705.
