Eastman Cadence™ GS5 Opaque White Copolyester for film calendering  (discontinued **)
Categories: Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film

Material Notes: Pigmented white using TiO2. 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.

Benefits

    Can 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 processes
  • Environmentally responsible material.

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.
