Tie layer is a new ultra-thin thermoplastic coating that can transform the medical device industry.
In this interview, Tara McCutchen, Senior Global Market Manager for Zeus, talks about their new tie layer and how it works in conjunction with FEP 2:1 heat shrink. high temp heat shrink tubing
Zeus now offers a new tie layer coating that can be applied onto our PTFE liners or just about any of our other tubing materials. Our standard off the shelf tie layer materials are Pebax, Tecoflex, and Vestamid and available in multiple durometers. Other materials are available upon request. The Tie Layer offers our customers:
With the addition of the tie layer, OEM’s and contract manufacturers can reduce delamination by increasing the liner to jacket bond strength up to 2.5X or higher depending on the catheter design. Improving bond strength reduces the likelihood of delamination occurring during a procedure, known as a field failure.While reducing delamination improves patient safety, it also reduces manufacturing cost by increasing yield, less inspection and higher throughput.
Zeus is already known in the medical industry as a best in class polymer solution supplier with extrusion as one of our core competencies. Tie layer is a great example of our ability to take a known biocompatible material and process it in a way that allows us to further complement our critical catheter components. For manufacturers who rely on PTFE liners, tie layer offers a solution that can reduce and possibly eliminate a high cost, high liability failure potential.

Delamination is one of the greatest risks in catheter construction. When different materials start to separate it limits the intended performance of that device and poses a major risk to patient safety. This defect is not easily detected and typically isn’t found until the final inspection of a fully assembled catheter. At this point, the entire catheter has to be scrapped, but even worse, a patient’s safety is at risk. With the addition of tie layer, the improved bond strength helps reduce such failures.
A Critical Bond You Can Count On
FEP 2:1 allows for reflow of catheter jackets with varying transitions. A good example of this would be reflowing over a tapered mandrel. With increased ratios, this could eliminate the use of multiple heat shrink pieces and less parts numbers for our customers. A one size fits most approach, if you will. Our 2:1 FEP HS is pure FEP and when removed it leaves a smooth surface finish.
Any application that needs improved adhesion, customized performance and limited on expanding the overall profile or wall thickness. We are diligently working on several new products that will provide additional benefits from our tie layer capability…stay tuned for more new product introductions from Zeus.
We believe our tie layer technology is the future for devices where adhesion and bondability are crucial to functionality. We have created tie layer solutions from the smallest of micro-catheters to the largest of structural heart catheters.
