Antioxidant 1076 (Irganox 1076)
CAS Number: 2082-79-3
Antioxidant 1076 is a hindered phenolic primary antioxidant (octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate) providing excellent long-term thermal oxidative stability for polyolefins, styrenics, and engineering polymers. It is particularly effective in applications requiring food-contact compliance and low volatility during high-temperature processing. Antioxidant 1076 is often combined with phosphite co-antioxidants for synergistic protection.
