BIONOX® 626 is a high performance organo-phosphite processing stabilizer which protects polymers from thermo-oxidative degradation during processing by decomposing hydroperoxides to form non-radical, non-reactive products. It can be used in polyethylene, polypropylene and ethylene-vinylacetate copolymers. It can also be used in other polymers such as engineering plastics, styrene homo- and copolymers, polyurethanes, elastomers, adhesives and other organic substrates.
