Texto del producto

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. Eastman Provista™ Copolymer ST is certified to NSF/ANSI Standard 51 for Food Equipment Materials.
