Eastman Chemical Co. announced Thursday that it will launch a new family of medical-grade polymers at the MedTec Europe trade show March 3 to 5 in Stuttgart, Germany. Medical grades of Eastman Tritan copolyester are clear polymers that deliver a balance of design, molding and end-product properties for medical devices.Medical grades of Eastman Tritan copolyester provide lipid and chemical resistance; higher heat stability; easy processing; excellent long-term clarity; added durability and toughness; and are made without bisphenol-A (BPA) or halogens. This combination allows the new material to perform at a level comparable to, or in many cases superior to, other polymers in the medical industry.“Eastman Chemical Co. has supplied a wide range of materials to medical customers for more than 65 years. Based upon our industry understanding, we are confident that the launch of Eastman Tritan copolyester in this market will provide customers with a high-quality product that provides processing and performance advantages over heritage copolyesters, polycarbonates and acrylics,” said Helen Sirett, medical business segment manager, Eastman Chemical Co.The new medical grades of Eastman Tritan™ copolyester are well-suited for a variety of medical-device applications that demand superior chemical resistance, clarity, hydrolytic stability and retention of properties after gamma, electron beam (E-beam) and Ethylene Oxide (EtO) sterilization. Additionally, Tritan™ provides exceptional protection against the negative effects of common materials that can lead to environmental stress cracking and deterioration in medical environments. Possible application options include IV system components, respiratory devices and blood therapy devices.Recently, products using Eastman Tritan™ copolyester have been launched in the reusable sports water bottle, infant care, small appliance and housewares markets. These products showcase a new level of design flexibility, and are tough, durable and BPA-free, while offering glasslike transparency without risk of breaking.
