Eastar™ GN007, Natural

Polyethylene Terephthalate Glycol Comonomer

Eastman Chemical Company

产品说明：

Eastar™ GN007 Copolyester is a water-clear glycol modified polyethylene terephthalate (PET) with an added mold release. Eastar™ GN007 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.
