PUREstab B215

PUREstab B215 by Vyridis is a processing and long-term thermal stabilizer system. It is a blend of PUREfos 168, a hydrolytically stable phosphite processing stabilizer and PUREstab 1010, a hindered phenolic antioxidant. It allows maintenance of original melt flow, low color formation and long-term thermal stability. PUREstab B215 is used in polyolefins and olefin-copolymers such as polyethylene, polypropylene, polybutene and ethylene-vinylacetate copolymers. Other applications include engineering plastics, styrene homo- and copolymers, polyurethanes, elastomers, and other organic substrates. Its recommended dosage level is 0.1-0.25% for polyolefins depending on substrate and processing conditions.
