| CALIBRE™ MEGARAD 2081-15 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 2081-15 resin can reduce the color shift by 50% compared to general purpose polycarbonate resins. CALIBRE 2081-15 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 higher energy radiation Tested under ISO 10993 Transparent Contains mold release Applications: Medical applications&& |
