PTFE Liners and Tubing

PTFE

liners

Hydromer offers three mainstream PTFE liner production processes: Free Extrusion/Over-The-Wire Extrusion (OTW)/Film Cast (OTW). Our engineers will select the right process based on different application scenarios and catheter designs to better match the combination of dimensions, strength, and flexibility.

3 Types of PTFE Processes

MatrixLiner® Extruded PTFE Liner:

Precise Dimensional & Performance Control

Hydromer’s free extrusion process deagglomerates PTFE resin crystals and forms aligned fibrillar structures, delivering exceptional strength and rigidity to the tubing.

The product includes the ToughFlex® (TF) series for high yield strength and the ElastiFlex® (EF) series for high elongation, offering greater flexibility for innovative medical catheter designs and customized performance.

  • Ultra-thin wall thickness: 0.0005 ± 0.00025"
  • Tight tolerances: WT Tol.: ± 0.00025" ID Tol.: ± 0.0005"

MatrixLiner® OTW PTFE Liner with Mandrel:

Perfect Balance of Strength & Wall Thickness
Hydromer’s mandrel extrusion technology integrates advanced processing principles to achieve high strength and flexibility simultaneously, while enabling ultra-thin walls and tighter dimensional control.
  • Ultra-thin wall thickness down to 0.0005"
  • Ultra-tight tolerances down to 0.0001"

MorphoLiner® Cast OTW PTFE Liner:

Ultimate Softness & Flexibility

Hydromer’s film-cast process produces extremely thin PTFE liners with a more isotropic microstructure that substantially lowers axial orientation compared with extruded PTFE, maintaining isotropic properties and delivering superior softness and flexibility.

  • Supports extreme wall thicknesses: 0.00025" / 0.001"
  • Ultra tight tolerances down to ± 0.0001"

Catheter Design Specialist
Eyedea Medtech Education/consulting

“After conducting an initial build and experimentation using JMedTech’s PTFE liners, I was truly impressed by the quality of the PTFE and etching. The liners were flexible, durable, easy to stretch, and performed extremely well during lamination. Even after destructive testing, the bond integrity remained exceptional. What impressed me equally was how easy the material was for inexperienced engineers and operators to use during our catheter education workshops, with no tearing, bunching, or damage. The quality of this work is a clear reflection of the knowledge and expertise behind it.”

Mini Tubing

We employ sophisticated processes to manufacture ultra-small inner diameter PTFE Mini Tubing, meeting the stringent precision requirements of high-end medical devices. Particularly for devices demanding superior stability and enhanced control, professional manipulation of the device distal end can be achieved by routing control wires through internal lumens.
Finer than a strand of hair. More precise than a pen tip.
  • Ultra-small inner diameter: 0.004-0.014″
  • Stable tolerance: ± 0.0005″
  • Ultra-thin wall thickness: 0.0005-0.001″

Product Advantages

  • Ultimate flexibility / high strength tailored to requirements
  • Highly customizable dimensions and performance
