RIANOX 626

A high performance, high molecular weight organo-phosphite processing stabilizer. Provides excellent color stabilization during compounding, fabrication and end use, and is highly effective at reducing polymer degradation during high-temperature processing. Also inhibits the catalytic action of metallic ions during the initial step of the oxidative mechanism. Higher phosphorus content than most competitive phosphite antioxidants at equivalent loading levels. FDA approved for food contact applications (21 CFR 178.2010).
