Antioxidant
Pentaerythritol tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate] (Irganox 1010) is a primary hindered phenolic antioxidant providing long-term thermal stabilization for polyolefins, engineering plastics, adhesives, and lubricants. It scavenges peroxy radicals generated during thermo-oxidative degradation, preventing discoloration and loss of mechanical properties. Demonstrates excellent synergy with phosphite co-antioxidants for comprehensive stabilization packages.
