Trinseo CALIBRE™ MEGARAD™ 2091-15 Polycarbonate Resin
Categories:	Polymer; Thermoplastic; Polycarbonate (PC); Polycarbonate, Gamma Radiation Resistant
Material Notes:	CALIBRE™ MEGARAD 2091 Polycarbonate resins designed for single use medical devices (SUDs) that require gamma and electron-beam irradiation and an accelerated schedule for delivery of post-radiated products to customers – potentially 10-21 days sooner than currently available radiation-stabilized polycarbonate resins, depending on irradiation conditions. In addition, the resins are meant for applications that require a more water white appearance rather than the traditional purple tinted resin used to compensate for these sterilization methods. CALIBRE™ MEGARAD 2091-15 Polycarbonate Resin has undergone biocompatibility testing based on ISO 10993 standards (Biological Evaluation of Medical Devices) and is suitable for use in approved medical applications. Main Characteristics: Improved Color Compensation Mold Release Tested under ISO 10993 Applications: Medical applications Information provided by Trinseo.
