Bayer MaterialScience LLC has developed a new medical grade polycarbonate resin that addresses the increasing demand for a radiation sterilizable material for thin-wall medical applications. The newly introduced Makrolon Rx2435 polycarbonate resin builds upon the proven efficacy of Makrolon® Rx2530. Like Makrolon Rx2530 polycarbonate, the new resin grade resin is said to exhibit good balance of mechanical strength and toughness. What differentiates Makrolon Rx2435 resin from previous medical grades is its ease of flow, which was enhanced specifically to meet the needs of thin-wall applications.
Like Makrolon Rx2530 polycarbonate, the new grade meets the requirements of U.S. Food and Drug Administration (FDA)-Modified ISO 10993, Part 1 "Biological Evaluation of Medical Devices" tests, the widely accepted standard for biocompatibility. Potential thin-wall applications for Makrolon Rx2435 include dialysis components, catheter connectors, surgical instruments - such as trocars, retractors and handles - and drug delivery devices. Makrolon Rx2435 polycarbonate is the latest in a long line of material innovations from Bayer MaterialScience.
