Eastman DuraStar DS1000 Polymer, Natural (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polycyclohexylenedimethylene Terephthalate (PCT); Glycol-Modified PCT (PCTG) Copolyester
Material Notes:	Durastar DS1000 polymer has excellent appearance and clarity. Its most outstanding features are chemical resistance and excellent processing characteristics. Exposure to aromatic oils often causes crazing or actual fracture of many polymer resins, but DS1000 maintains its physical properties when exposed to these oils, and its appearance is virtually unchanged. Easy to process, it flows readily, fills intricate molds, and is well suited for thick-wall applications. Under existing United States Food and Drug Administration (FDA) regulations, Durastar DS1000 may be used in food contact articles which comply with the specifications and conditions of use in 21 CFR 177.1240. Applications/Uses Floor care Housewares Toys/Sporting goods Furniture/Furniture trim Point of purchase displays Writing instruments Key Attributes Good chemical resistance Excellent flow Outstanding impact resistance Excellent clarity Fast drying times Quick cycle times
