Trinseo CALIBRE™ MEGARAD 2080 15 Polycarbonate, Gamma Radiation Resistant  (discontinued **)
Categories: Polymer; Thermoplastic; Polycarbonate (PC); Polycarbonate, Gamma Radiation Resistant

Material Notes: CALIBRE® MegaRad 2080 series resins provide 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 2080 series resins exhibit a 50% reduction in color shift compared to general purpose polycarbonate.

Typical applications(1) are hemodialyzers, anesthesia containers, blood oxygenators, arterial filters, intravenous connectors, cardiotomy reservoirs, arteriograph manifolds, blood centrifuge bowls and physiological pressure transducers.

Available Melt Flow Rates: 10, 15.

Associated products:
CALIBRE MegaRad 2080: without a mold release package
CALIBRE MegaRad 2081: including a mold release package

(1) NOTICE REGARDING LONG-TERM MEDICAL IMPLANT APPLICATIONS: The Dow Chemical Company does not recommend any medical resin or film product for long-term medical implant applications in humans (more than 72 hours). Further, Dow does nor recommend the use of any medical resin or film product for cardiac prosthetic devices regardless of the time period that the device will be wholly or partially implanted in the body. Such applications include, but are not limited to, pacemaker leads and devices, cardiac prosthetic devices, such as artificial hearts, heart valves, intra-aortic balloon and control systems, and ventricular bypass assist devices. Dow does not recommend any nonmedical grade resin product for use in any human implant applications.

Where available, biocompatibility data relates to resins, not necessarily to fabricated products. Manufacturers of medical devices, equipment and packaging are responsible for determining the suitability of resins for their intended use.
