High-performance phosphite antioxidant offering exceptional melt stability for polyolefins during high-temperature processing.
Excellent hydrolytic stability, minimizing degradation in humid or aqueous environments during storage and compounding.
Low volatility ensures long-term retention in finished products, supporting extended service life under thermal stress.
Synergistic with hindered phenols (e.g., Irganox 1010), enabling optimized antioxidant package performance at reduced loading levels.
Non-staining and low odor—ideal for applications requiring aesthetic and sensory integrity, including packaging and consumer goods.
Polypropylene (PP) fibers and nonwovens used in geotextiles, filtration media, and hygiene products.
High-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) blow-molded containers and pipes.
Automotive interior components, including PP-based dashboards, trim, and under-hood parts exposed to elevated temperatures.
Food-contact compliant polyolefin packaging films and rigid containers meeting FDA and EU regulatory requirements.
Recycled polyolefin formulations where enhanced stabilization is required to counteract accumulated oxidative damage.
