High-performance hindered phenolic antioxidant with exceptional thermal and oxidative stability.
Low volatility and excellent compatibility with polyolefins, engineering plastics, and elastomers.
Non-staining and low-color formation—ideal for light-colored and transparent polymer applications.
Good hydrolytic stability and resistance to extraction during processing or end-use.
Meets stringent regulatory requirements including FDA 21 CFR §178.2010 for food-contact polymers (when used within approved limits).
Polypropylene (PP) fibers, films, and injection-molded automotive parts.
Polyethylene (PE) pipes, geomembranes, and rotational molding containers.
Thermoplastic elastomers (TPEs) and thermoplastic vulcanizates (TPVs).
Recycled polyolefin compounds requiring robust stabilization against reprocessing degradation.
Medical-grade polyolefin components where low extractables and biocompatibility support are critical.
