Material Notes:
Eastar PCTG 5445 is an amorphous copolyester. Because of its clarity, toughness and good melt strength, Eastar PCTG Copolyester 5445 is useful in a number of applications. It has high gloss and is transparent. It is tough and resistant to stress whitening. It has fast forming cycles and is easy to form. Eastar PCTG Copolyester 5445 is sterilizable by both gamma radiation and ethylene oxide (ETO) methods. Its scrap can be reused.Applications/UsesBagsCredit cardsGaming cardsIdentification cardsPlastic CardsRigid medicalBlister packagingDebit cardsGift cardsPhone cardsRapid deployment flood wallsSmart cardsKey AttributesExcellent clarityEffective barrier propertiesExcellent colorabilityGood stiffnessSterilizable with ethylene oxide, electron beam, and gamma rays
