Material Notes:
Eastman Cadence™ copolyester, for calendered films, is a specialty plastic developed to meet the demand for an environmentally responsible material for the calendering industry. Available in different grades, it features ease of processing, high-melt strength, aesthetics, clarity and gloss.BenefitsCan be used on existing calendering lines with no or minimal modification.No drying is needed prior to the calendering process.Good thermal stability during normal calendering process conditions.No corrosive degradation products are normally formed.Easy to emboss for added texture and dimensions with standard engraved rolls. Easy to decorate using offset lithography, flexographic, and screen-printing processes.Thermoforms easily and is compatible with commercial adhesives used in lamination processesEnvironmentally responsible material.Product description: Eastman Cadence GS5 is an amorphous copolyester with improved processability for film calendering. Calendered films made of Eastman Cadence copolyesters are non-crystallizing, are halogen-free, offer wide calendering and thermoforming windows and have good low-temperature toughness. They are cooperative in secondary operations such as solvent-bonding, lamination, decoration, cold-forming, punching/cutting and embossment.Eastman Cadence resins require no pre-drying or additional stabilizers.Application/UsesAppliance filmsArchitectural laminatesAutomotive filmsBagsDecorative laminatesElectronic laminatesFloor coveringsFurniture/Furniture trimLabelsOutdoor filmsPackagingPrintable filmsShrink filmTransaction cardsTransportation laminatesWall coveringsReported typical properties are preliminary.
