Eastman Provista™ Copolymer ST is a resin specifically developed for profile extrusion where high clarity and gloss, toughness, and processability are critical. Eastman Provista™ Copolymer ST is a second-generation material that complements Eastman Provista™ by offering similar features, while providing greater toughness. Eastman Provista™ Copolymer ST is ideal in applications that place greater physical demands on the profile. This product has been GREENGUARD INDOOR AIR QUALITY CERTIFIED®. The GREENGUARD INDOOR AIR QUALITY CERTIFIED® Mark is a registered certification mark used under license through the GREENGUARD Environmental Institute (GEI). GEI is an industry-independent, non-profit organization that oversees the GREENGUARD Certification Program.
