High-performance phosphite antioxidant offering exceptional melt stability during high-temperature polymer processing.
Excellent hydrolytic stability compared to conventional aryl phosphites, ensuring consistent performance in humid or moisture-sensitive operations.
Low volatility and thermal stability up to 300 °C, minimizing plate-out and odor generation in extrusion and injection molding.
Synergistic with hindered phenolic antioxidants (e.g., Irganox 1010), enabling optimized stabilization packages for polyolefins and engineering thermoplastics.
Non-staining and compatible with a broad range of polymers including PP, HDPE, LDPE, and polyesters.
Polypropylene (PP) fibers and nonwovens for hygiene and medical applications.
Automotive interior components requiring low VOC and long-term thermo-oxidative stability.
Food-contact packaging films and containers made from polyolefins.
Thin-gauge blow-molded bottles and caps where processing stability and clarity retention are critical.
Engineering thermoplastics such as polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) used in electrical connectors.
