Trinseo CALIBRE™ MEGARAD™ 2081-15 Polycarbonate Resin
Categories: Polymer; Thermoplastic; Polycarbonate (PC); Polycarbonate, Gamma Radiation Resistant

Material Notes: CALIBRE™ MEGARAD 2081-15 Polycarbonate resin provides end-user 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™ MEGARAD 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
