Eastman Provista UVI Copolymer
Categories:	Polymer; Thermoplastic; Polyester, TP
Material Notes:	Provista UVI is a Provista copolymer with an indoor/outdoor UV package added to prevent yellowing caused by light. 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, Provista copolymer 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.
