Trinseo CALIBRE™ MEGARAD 2081-6LR Polycarbonate Resin
Categories:	Polymer; Thermoplastic; Polycarbonate (PC); Polycarbonate, Gamma Radiation Resistant
Material Notes:	CALIBRE™ MEGARAD 2081-6LR Polycarbonate resin was developed for medical applications requiring improved resistance to lipids over standard polycarbonate resin. When exposed to a 20% intralipid emulsion solution under strained conditions, CALIBRE™ MEGARAD 2081-6LR exhibits significant property retention compared to standard polycarbonate. It also 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 2081-6LR can reduce the color shift by 50% compared to general purpose polycarbonate resins. Main Characteristics: Improved lipid resistance Stabilized for high-energy radiation Tested under ISO 10993 Transparent Contains mold release Applications: Medical applications Information provided by Trinseo.
