VANOX^® 961

VANOX^® 961 is a liquid amine antioxidant that suppresses scorch development during flexible polyurethane foam production. It provides additional benefits as an economical replacement for conventional solid diphenylamine-based antioxidants, often used in conjunction with hindered phenols by polyol manufacturers as their basic scorch inhibitor package. Blends composed of liquid hindered phenols and VANOX 961 are also stable at low temperatures and easier to convey with transfer pumps.
