Eastman Provista™ Copolyester (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP
Material Notes:	Product Description: Eastman Provista™ copolymer is a resin specifically developed for extrusion into profiles where aesthetics like high clarity and gloss, coupled with design flexibility drive demand. Compared to commonly used materials, Eastman Provista™ copolyester can often run on most standard processing equipment at increased speeds. An extremely high melt strength makes the resin an excellent choice when extruding profiles into complicated shapes. This product is certified to ANSI/NSF Standard 51. Application/Uses: Candy packaging Displays, Fixtures and Point of purchase Food packaging Furniture guards Plastics for hygiene feminine products Pricing channels Teething rails Tubing Key Attributes: Ease of processing Excellent chemical resistance Meets FDA regulations for food contact Sparkling clarity and high gloss Toughness with flexibility Information provided by Eastman
