Product Description
We provide comprehensive OEM and contract manufacturing services for PTFE Liners, designed as ultra-low friction inner lumens for advanced catheter shafts and interventional medical devices. Our engineering and manufacturing platforms support full-cycle execution from precision extrusion and micro-wall thickness control to surface-etched treatment for enhanced bonding, tailored to client specifications.
Features
Ultra-Low Friction: Exceptionally low coefficient of friction ensuring smooth delivery of guidewires and microcatheters.
Micro-Wall Thickness: Precision control for ultra-thin wall profiles, maximizing internal lumen space while minimizing outer catheter profile.
Chemical Inertness: Biocompatible and chemically inert material compatible with a wide range of contrast media and therapeutics.
Enhanced Bonding (Etched Surface): Optional chemical etching on the outer surface to ensure superior adhesion with outer jacket polymers (such as PEBAX, TPU, or Nylon).
Kink Resistance & Flexibility: Excellent structural flexibility and stability during catheter tracking through tortuous anatomy.
