Overview
ANOX™ BB021 is a solid-powder synergistic blend of one part phenolic (ANOX™ 20) to two parts phosphite (ALKANOX™ 240) antioxidants. This binary blend imparts excellent protection from thermal degradation for polymers during both processing and long-term aging. A high–molecular weight hindered phenol blend, ANOX™ BB021 protects polyolefins with the low volatility of both ANOX™ 20 (33%) and ALKANOX™ 240 (67%).
