PTFE Coating Options and Capabilities
Merit Medical Coatings applies PFOA-free polytetrafluoroethylene (PTFE) coating to medical tubes and round or flat wires. We offer coating options that vary in lubricity and texture and can meet the requirements of nearly any medical device tubing or wire. Coatings are applied using our world-renowned spool-to-spool process prior to further processing.
