Hindered phenolic antioxidant and polymer stabilizer for PE/PP/PS, adhesives, coatings, and elastomers; improves processing and long-term oxidative stability.

Irganox 1076 (Polymer Antioxidant) is a hindered phenolic antioxidant used to protect polymers against thermal and oxidative degradation.

Widely used in polyolefins (PE, PP), styrenics (PS, ABS), adhesives, coatings, and elastomers to improve processing stability and long‑term heat/oxidative resistance.

Acts as a primary antioxidant by scavenging peroxy radicals and interrupting autoxidation chains. Often combined with phosphite or thioester secondary antioxidants for synergistic stabilization.
