Trinseo CALIBRE™ MEGARAD 2080-10 Polycarbonate, Gamma Radiation Resistant
Categories:	Polymer; Thermoplastic; Polycarbonate (PC); Polycarbonate, Gamma Radiation Resistant
Material Notes:	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 electronic 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 base 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 Contains mold release Application: Medical applications Data provided by Dow Chemical. This product line was spun off from Dow Chemical to Styron in 2010.
