Catheter Tie Layer

Zeus, Orangeburg, SC, offers a thin thermoplastic coating that is placed over a PTFE liner during catheter construction. The Zeus Tie Layer creates a melt bondable surface that improves adhesion to the catheter jacket following the reflow process. Used in this way, it improves jacket-to-liner bond strength and enhances mechanical properties of the finished device. Better jacket-to-liner bond strength helps promote improved patient care and fortifies the catheter.
