| CALIBRE™ MEGARAD 2081-10 Polycarbonate resin provides end-users of radiation sterilized medical devices a color closer to the water-clear look of the natural resin. When exposed to high energy radiation (gamma or electron beam), CALIBRE MEGARAD 2081-10 resin can reduce the color shift by 50% compared to general purpose polycarbonate resins. CALIBRE 2081-10 resin has undergone biocompatibility testing based on ISO 10993 (Biological Evaluation of Medical Devices) and is suitable for use in approved medical applications. Main Characteristics Stabilized for high energy radiation Tested under ISO 10993 Transparent Contains mold release Applications: Medical applications&& |
