Eastman Eastar GN102 Copolyester (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET); Polyethylene Terephthalate (PET), Unreinforced
Material Notes:	Eastar GN102 copolyester is a glycol modified polyethylene terephthalate (PET) that contains an ultraviolet inhibitor and mold release. Eastar GN102 copolyester will not crystallize and thus offers wider processing latitude than conventional crystallizable polyesters. This material offers an excellent combination of clarity, toughness, and melt strength that makes it useful for a variety of processing techniques and end-use applications. Applications/Uses Lighting
