MATERIALS: To manufacture its UltraSafe Passive® Needle Guards, Safety Syringes Inc. needed to find a material that was not only robust and transparent, but also offered improved flow, lubricity and easy release characteristics.
Bayer MaterialScience LLC met Safety Syringes’ requirements with Makrolon® Rx1851 polycarbonate, a low-viscosity resin with enhanced internal mold release technology that provides increased design flexibility for complicated parts.
The product, a single-use, anti-needle-stick device for pre-filled injectable syringes, is composed of two telescoping plastic components and a spring. The body component of the device is injection molded using the Makrolon Rx1851 resin.
The medical grade resin is supplied in pellet form for injection-molded applications. It is available in clear tint as well as in other Rx Medical colors from Bayer MaterialScience LLC’s LEDA® compounded color technology, all of which meet U.S. Food and Drug Administration (FDA)-Modified ISO 10993, Part 1, “Biological Evaluation of Medical Devices” tests.
