You can expect a balance of important advantages with new Eastman Tritan™ copolyester, making it well-suited for a variety of medical-device applications.

Chemical resistance
Common substances found in the medical environment can cause stress cracking and functional deterioration of medical devices. Eastman Tritan™ copolyester resists the negative effects of exposure to lipids, isopropyl alcohol, disinfecting agents and bonding solvents. View validation trial

Toughness Eastman
Tritan™ copolyester offers impact and shatter resistance that is comparable to the most popular polycarbonates, without the added time and energy requirements of an annealing step. This means few broken parts, reduced part failures, less waste and ultimately greater customer satisfaction. View validation trial

Hydrolytic stability
The unique chemistry of Eastman Tritan™ copolyester provides enhanced heat resistance, making it a compelling choice for medical-device applications with exposure to heat, humidity and chemical agents. Due to the superior hydrolytic stability of Tritan, parts are less likely to crack or craze. View validation trial

Sterilization
Sterilization techniques, including gamma irradiation, electron beam (E-beam) and Ethylene Oxide (EtO), do not negatively affect the color stability or the mechanical properties of Eastman Tritan™ copolyester. View validation trial

Clarity
The glass-like transparency of Eastman Tritan™ copolyester conveys safety and quality, which means peace of mind for healthcare professionals and patients.

Ease of processing
The unique chemistry of Eastman Tritan™ copolyester enables easier processing and faster cycle times. Molded part shrinkage is similar to that of polycarbonate.

Bisphenol-A (BPA) free
Eastman™ copolyesters and cellulosics are environmentally responsible materials that are free of orthophthalate plasticizers, BPA and halogens.
