Description
Fobos Polymer manufactures precision PTFE thin wall tubing for medical catheters, catheter components, and minimally invasive interventional devices. Our thin-walled PTFE tubes are engineered for applications where compact geometry, smooth surface finish, chemical resistance, and tight dimensional control are critical.
Compared with standard PTFE tubing, thin-wall construction provides a smaller outer diameter and improved space efficiency while retaining PTFE’s inherent low friction and chemical resistance. This makes our tubing ideal for catheter liners, guide tubes, fluid transfer lines, and interventional device components.
All Fobos PTFE thin wall tubing is produced under strict quality control and is available with custom ID, OD, wall thickness, length, and clean packaging according to your project requirements.
Typical Catheter Applications
Catheter liners and protective tubing
Minimally invasive interventional guide tubes
Stent delivery system components

Material Advantages for Catheter Applications
PTFE is widely used in medical catheters due to its exceptional material properties:
Chemical resistance – Inert to virtually all chemicals, solvents, acids, and bases
Low friction – One of the lowest coefficients of friction among engineering materials, enabling smooth delivery through vasculature
Wide temperature range – Stable performance from cryogenic to 260°C (500°F)
Biocompatibility – ISO 10993 compliant, suitable for contact with biological systems
Dielectric strength – Excellent electrical insulation properties
Low extractables – Minimal contamination risk for clean fluid handling
For catheter projects, PTFE tubing is selected because it supports smooth fluid transfer, stable sliding performance, and reliable dimensional behavior. Final material validation should be confirmed according to your application, testing requirements, and regulatory standards.
