High-performance phenolic antioxidant with synergistic phosphite functionality for superior thermal and oxidative stability.
Low volatility and excellent melt stability, ideal for high-temperature polymer processing (up to 300°C).
Compatible with polyolefins, engineering plastics, and elastomers without compromising mechanical properties or color stability.
Non-staining and low extractability, meeting stringent requirements for food-contact and medical-grade polymers.
Readily dispersible in molten resins and compatible with common co-stabilizer systems (e.g., HALS, thioesters).
Polypropylene (PP) fibers and nonwovens for hygiene and medical applications.
High-density polyethylene (HDPE) pipes and geomembranes requiring long-term environmental stress crack resistance.
Automotive interior components including PP/TPO dashboards and door trims.
Food packaging films and rigid containers based on polyolefin blends.
Recycled polyolefin compounds where enhanced stabilization against reprocessing degradation is critical.
