High-performance hindered phenolic antioxidant offering exceptional thermal and oxidative stability.
Low volatility and excellent compatibility with polyolefins, styrenics, and engineering thermoplastics.
Effective at low dosage levels (0.05–0.3 wt%), minimizing impact on polymer color and mechanical properties.
Resists extraction during hot water or solvent washing, ensuring long-term protection in demanding environments.
REACH-compliant and free of heavy metals, meeting stringent global regulatory requirements for food-contact and medical-grade polymers.
Polypropylene (PP) and polyethylene (PE) fibers, films, and injection-molded parts.
Automotive interior components exposed to elevated temperatures and UV stress.
Food packaging films requiring FDA-compliant stabilization and clarity retention.
Medical tubing and disposable devices where biocompatibility and processing stability are critical.
Recycled polymer streams needing robust melt stabilization during reprocessing.
