Product Description
Eastman Cadence GS1 is Eastman's original copolyester 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.
