jMedtech PTFE Liners and Heat Shrink Tubing Now Available on Chamfr
R&D teams are constantly balancing competing constraints in catheter development: smaller profiles, reliable layer bonding, and repeatable manufacturing performance.
One of the most critical components in that equation is the PTFE liner. Small changes in wall thickness or tolerance can significantly impact how easily a catheter design moves from concept to prototype and verification.
jMedtech just launched 25 new components on Chamfr, including PTFE liners and heat shrink tubing, designed to help you prototype faster and push beyond profile limits without sacrificing lubricity.
Why PTFE Liners Are Critical in Catheter Development
In multi-layer catheter shafts, the PTFE liner typically forms the innermost lubricious layer, enabling smooth device delivery.
The liner must support several competing requirements:
- Maintain low friction for guidewire or device delivery
- Provide consistent wall thickness and tolerances
- Allow strong bonding to outer jackets
- Maintain structural integrity through reflow and lamination processes
Achieving these requirements becomes even more difficult as device profiles shrink and shaft designs become more complex.
jMedtech’s portfolio addresses these challenges through a combination of thin walls, tight tolerances, and etched/bonding-layer surfaces that improve multi-layer shaft adhesion.

MatrixLiner® Free-Extruded PTFE Liners
These thin wall PTFE liners enable smaller OD catheters and increased ID without increasing overall profile, ideal for distal designs where space is constrained.
Key Specs:
- ID: 0.0039” – 0.2382”
- OD: 0.0055” – 0.2421”
- Wall: 0.0005” – 0.002”
- Etched or bonding-layer surface treatment for improved jacket adhesion while maintaining lubricity
- Supports Autoclave and EtO sterilization
MatrixLiner® Free-Extruded PTFE Liners With SPC
PTFE liners with silver-plated copper (SPC) support complex catheter designs requiring precise inner diameters and ease of manufacturing with built-in mandrel.
Without sacrificing lubricity and performance.
MorphoLiner™ Casted (Film-Cast/Dip-Coated) OTW PTFE liners
Reduce iteration cycles with a biocompatible film-cast/dip-coated OTW PTFE liner, enabling smooth surfaces and strong dimensional control.
Key Specs:
- ID: 0.0225”
- OD: 0.024”
- Wall: 0.00075”
For engineers working on precision catheter applications, these tolerances can help improve predictability in laminations, reflow, and braid/coil integration.
PTFE Heat Shrink Tubing
jMedtech’s expanded portfolio also includes standard and zebra spiral PTFE heat shrink for guidewire encapsulation and component insulation.
Standard Heat Shrink Key Specs:

Common Applications
Supporting a wide range of applications, jMedtech’s PTFE liners are commonly used in:
- Microcatheters and neurovascular delivery
- Guide and support catheters
- Mechanical thrombectomy and aspiration systems
- Midline and peripheral access catheters
- Adjustable and suction catheters
Heat shrink tubing is typically used for guidewire encapsulation, endoscopy components, and electrosurgical instrument insulation.
