Product Texts

Eastman Cadence™ GS3 is a clear copolyester resin specifically for calendered film applications including

decorative laminates, general purpose packaging, transaction and identification cards, and protective films. It has

enhanced processing ease and higher melt strength compared to Cadence™ GS2.

Film producers looking to replace PVC and other materials of concern choose Cadence™ for its ease of processing,

low-temperature toughness, and the ability to be downgauged – all of which help reduce cost. It has a wide

calendering and thermoforming window, which enables Cadence™ to be used on most existing calendering lines

and thermoforming equipment with little or no modification. Eastman Cadence™ resins require no pre-drying or

additional stabilizers.
