Evonik Cyro Manufacturers Antimicrobial Polymer for Medical Devices

Posted in Medical Plastics by Chris Wiltz on November 26, 2012

A specialty chemical company manufactures an acrylic-polycarbonate alloy for medical device construction. Designed to be tough, strong, and opaque, the Cyrex Protect features antimicrobial properties that are built into the material during manufacturing. Thus, devices made from this polymer deliver reliable protection against a variety of microorganisms found in healthcare facilities. In addition, they require no active surface coating that could scratch or wear off and consequently diminish antimicrobial effectiveness. Designed for the manufacture of such Class I and Class II medical devices as luer connectors, spikes, y-sites, check valves, and filter housings, the material offers a notched Izod impact test value of 12 ft-lb/in. It has demonstrated efficacy greater than 4 when tested according to the JIS Z 2801 protocol against Staphylococcus aureus, Pseudomonas aeruginosa, Staphylococcus epidermidis, and Klebsiella pneumoniae after both 24 hours and 96 hours of exposure, according to the company. The polymer is also resistant to plasticizers found in flexible PVC and can be sterilized by means of gamma, E-beam, and EtO techniques.
