BPA-Free
Eastman Tritan™ copolyester is free of bisphenol-A (BPA), orthophthalate plasticizers, and halogens.

Sterilization
Both E-beam and gamma radiation are known to cause changes to the color of polymers during exposure — change which can impact aesthetics, color coding options, and even functional integrity. For any application that does not require autoclaving, Eastman Tritan™ copolyester is a practical and reliable solution.
