High-performance sterically hindered phenolic antioxidant with exceptional thermal and oxidative stability.
Excellent compatibility with polyolefins, styrenics, and engineering thermoplastics.
Low volatility and minimal migration, ensuring long-term protection during processing and end-use.
Effective at low dosage levels (typically 0.1–0.5 wt%), delivering cost-efficient stabilization.
Non-staining and non-discoloring—ideal for light-colored and transparent polymer applications.
Polyethylene (HDPE, LDPE, LLDPE) pipes, films, and injection-molded articles.
Polypropylene (PP) fibers, automotive components, and medical packaging.
Styrenic resins including ABS, HIPS, and SAN for durable consumer goods.
Thermoplastic elastomers (TPEs) and polyolefin-based blends requiring extended service life.
Cable & wire insulation compounds exposed to elevated temperatures and environmental stress.
