Tritan™ MX731 copolyester, a new high-flow, medical-grade polymer, features exceptional chemical-resistance and hydrolytic stability, as well as competitive toughness, gloss and processability, the co. states. The polymer is suitable for use with hand-held medical-device applications, such as diagnostic tools, blood-glucose meters, pulse oximeters and battery-powered feeding pumps in which close contact with the skin and cleaning with chemicals is common. The polymer also resists chemicals used in disinfectants and cleansers without cracking or crazing, and offers added toughness to medical parts, particularly hand-held medical devices that are utilized frequently and could be dropped, the co. says.
