Highly effective phenolic antioxidant with synergistic activity in polymer matrices.
Excellent thermal stability up to 230°C during processing of polyolefins and engineering plastics.
Low volatility and minimal migration, ensuring long-term stabilization in end-use applications.
Compatible with common co-stabilizers including phosphites and thioesters.
Non-staining and low-color formation, suitable for light-colored and transparent polymer formulations.
Polypropylene (PP) fibers and nonwovens for medical and hygiene products.
High-density polyethylene (HDPE) pipes and geomembranes exposed to outdoor UV and thermal stress.
Automotive interior components requiring low fogging and odor compliance.
Food-contact compliant polyolefin packaging films and containers.
Recycled polyolefin compounds where oxidative degradation resistance is critical.
