Eastman Eastar GN125 Copolyester, Natural (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET); Polyethylene Terephthalate (PET), Unreinforced
Material Notes:	Eastar Copolyester GN125 is a glycol modified polyethylene terephthalate (PET) that contains an ultraviolet light inhibitor. This product is recommended for indoor applications requiring enhanced color stability. Eastar copolyester GN125 will not crystallize and as a result, offers a wider processing latitude than conventional crystallizable polyesters. This product offers an excellent combination of clarity, toughness, and melt strength that makes if useful for a variety of processing techniques and end-use applications.
