High-performance, non-staining phenolic antioxidant for demanding polymer stabilization.
Excellent thermal and long-term oxidative stability in polyolefins and engineering thermoplastics.
Low volatility and high melt stability, minimizing plate-out and improving processing consistency.
Compatible with other additives including phosphites, thioesters, and HALS stabilizers.
Meets FDA 21 CFR §178.2010 for indirect food contact applications in polyolefin resins.
Polypropylene (PP) fibers, films, and injection-molded automotive parts.
High-density polyethylene (HDPE) and low-density polyethylene (LDPE) blow-molded containers.
Polybutylene terephthalate (PBT) and polyamide (PA6, PA66) under high-temperature processing.
Rotational molding and pipe extrusion compounds requiring extended thermal stability.
Medical-grade polyolefin components where color stability and biocompatibility are critical.
