Chemical Resistance Plaques


Chemical Resistance with Externally Applied Stress

Inherent chemical resistance is one of the greatest benefits of using Eastman Tritan™ copolyester for medical devices. Adding external force dramatizes this benefit, with implications for secondary operations, toughness, and device durability.

These photographs show the results of a comparison of Eastman Tritan™ copolyester MX711, with lipid-resistant polycarbonate, general purpose polycarbonate and general-purpose acrylic. For details of the study and more information about Tritan, follow the links below.
