Film-Cast Liner Tubing

Film-Cast PTFE Liner Tubing

Enhance Your Medical Devices

When your catheter assembly needs a lubricious inner layer, a PTFE liner is the ideal choice. But not all PTFE liner tubing is the same. We supply etched PTFE liners on solid, silver-plated copper-core mandrels, which give you the advantage of having thinner walls and time savings.

Advantages

Film-Cast PTFE Liner Tubing

What makes our PTFE liners different? We provide them on silver-plated, copper-core mandrels, so you don't have to stretch the liner onto another mandrel.

Other advantages include:

Ultrathin walls (0.0004" - 0.002")
Precise dimensions
High flexibility with minimal stiffness added to the catheter shaft
Improved adhesion with strike layer (a thin thermoplastic outer layer to enhance adhesion)
Option of cut lengths or continuous-spooled lengths

Strike Layer

Enhancing Adhesion

Our PTFE liners on mandrels can be fabricated with a thin thermoplastic outer layer to enhance adhesion. This "strike layer" adds more bond strength between the etched PTFE surface and the catheter assembly. Strike layers are available in a wide range of thermoplastic materials, including, but not limited to:

Nylon (11 and 12)
Pebax® (55D, 70D, 72D, and others available)
Polyurethane (Tecoflex®)

Ram-Extruded Tubing

Made With PTFE

Choose Nordson MEDICAL, and choose one of the world's leading manufacturers of custom ram-extruded PTFE tubing for the medical industry.

Removing the Mandrel

Our silver-plated, copper-core mandrels stay put through the entire catheter assembly process. Our mandrels are malleable, which makes them easy to remove. When your catheter is complete, simply pull the ends of the mandrel outward to reduce the diameter, and your PTFE-lined catheter assembly will slide off.
