Trinseo CALIBRE™ MEGARAD 2081-HD-15 2 Polycarbonate Resin  (discontinued **)
Categories: Polymer; Thermoplastic; Polycarbonate (PC); Polycarbonate, Gamma Radiation Resistant

Material Notes: Overview: CALIBRE™ MEGARAD 2081 HD-15 2 polycarbonate resin provides end-users of radiation sterilized medical devices a color closer to the water-clear look of the natural resin. When exposed high energy radiation (gamma or electron beam), CALIBRE MEGARAD 2081 HD-15 2 resin can reduce the color shift by 50% compared to general purpose polycarbonate resins. CALIBRE MEGARAD 2081 HD-15 2 resin has undergone biocompatibility testing based on ISO 10993 (Biological Evaluation of Medical Devices) and is suitable for use in approved medical applications. This product contains mold release.

Main Characteristics:

  • ISO 10993
Applications:
  • Medical Applications
