Overview
ANOX™ 29, from SI Group, is a sterically hindered bisphenol antioxidant tremendously effective at preventing thermo-oxidative degradation during processing, storage, and end use in various materials. It synergizes with thioesters to offer enhanced thermal aging properties in polypropylene. ANOX™ 29 stabilizer protects from heat and oxygen degradation for plastics, including crystal and high-impact polystyrenes, ABS terpolymers, PVC, polyamide nylons, polyurethanes, elastomers, adhesives, EPDM, SBS, and rubber blends with polyolefins. Furthermore, ANOX™ 29 can work with natural and synthetic tackifier resins.
