Eastman Eastar AN004 Natural PCTA Copolyester
Categories:	Polymer; Thermoplastic; Polyester, TP; PCTA Polyester Alloy; Polycyclohexylenedimethylene Terephthalate (PCT)
Material Notes:	Eastar™ AN004 Copolyester contains a mold release. It has excellent appearance and is nearly water-clear. It features are its chemical resistance and processing capabilities. Exposure to aromatic oils often causes crazing or actual fracture of many polymer resins, but AN004 maintains its physical properties when exposed to these oils, and its appearance is virtually unchanged. Easy to process, it flows readily and fills intricate molds. Its processability coupled with its outstanding chemical resistance makes it well suited for thick-wall applications. Application/Uses: Compacts Cosmetic jar caps Cosmetic jars Cosmetics/personal care packaging Fragrance caps Fragrance packaging Lipstick containers Personal care bottles Key Attributes: Easy to extrude, cut, print, and seal Effective barrier properties Excellent chemical resistance Excellent clarity Excellent colorability Good impact strength Good stiffness High gloss appearance Toughness
