Film-Cast PTFE Liner Tubing

What sets our PTFE liners apart? We offer them on silver-plated, copper-core mandrels, eliminating the need for stretching the liner onto another mandrel. Additional advantages include:

  1. Exceptionally thin walls (ranging from 0.00032" to 0.002").
  2. Precise dimensions.
  3. Remarkable flexibility with minimal stiffness added to the catheter shaft.
  4. Enhanced adhesion due to a strike layer (a thin thermoplastic outer layer).
  5. The choice between cut lengths or continuous-spooled lengths.

Removing the Mandrel

Our silver-plated, copper-core mandrels remain securely in place throughout the entire catheter assembly process. These mandrels are designed to be pliable, facilitating effortless removal. Once your catheter is finished, a simple outward pull on the mandrel ends reduces its diameter, allowing your PTFE-lined catheter assembly to effortlessly slide off.

Strike Layer Enhances Adhesion

Our PTFE liners on mandrels can be customized with a thin thermoplastic outer layer, known as a "strike layer," to augment adhesion. This additional layer significantly enhances the bond strength between the etched PTFE surface and the catheter assembly. We offer a diverse selection of thermoplastic materials for strike layers, including, but not limited to:

  1. Nylon (11 and 12)
  2. Pebax® (55D, 70D, 72D, and other variants available)
  3. Polyurethane (Tecoflex®)
