Why are medical professionals all talking about PTFE tube? A material that gives catheters the confidence to slide smoothly, stand strong, and bond reliably.

You may not know that the core underlying material shared by many familiar products—such as injection needles, catheter liners, and thermal snare outer shafts—is a polymer called PTFE.

Different processing techniques and dispersion media define its performance limits. And we have selected the grade most suitable for medical-grade single-lumen tube.

PTFE Material Classification: More Than Just "Fluoroplastic"

PTFE, short for Polytetrafluoroethylene, is known for its low friction coefficient, excellent biocompatibility, corrosion resistance, and high chemical inertness. It is widely recognized as the "noble material in the industry."

PTFE is categorized into three types based on processing technology and dispersion media:

Common Specifications of PTFE Extruded tube

Common Specifications of PTFE Thin-Wall tube / Etched tube

Our company uses dispersed PTFE, with all raw materials supplied by Daikin (Japan). Featuring stable quality and superior processability, it meets the stringent requirements of medical devices for high cleanliness, high dimensional consistency, and chemical resistance.

PTFE single-lumen tube is indispensable in the following medical applications:

• Main medical applications of PTFE single-lumen tube: inner and outer shafts for injection needles, outer tube for thermal snares, etc.

• PTFE thin-wall tube is widely used for liners, insulation, sliding components, and precision fluid control in catheter systems. It is a critical component in high-end medical devices such as electrophysiology catheters and energy-based catheters.

• PTFE etched tube: inner liner for composite catheters.
