High-Precision PTFE Tubing Fully Customizable Production Supported
PTFE (polytetrafluoroethylene, commonly known as Teflon or “Plastic King”) tubing is a specialty tubing manufactured from PTFE resin through extrusion, sintering, and other processes. It offers an unparalleled combination of properties among engineering plastics–extreme temperature resistance, resistance to virtually all chemicals, self-lubrication, non-stick surface, and excellent electrical insulation, making it one of the most advanced specialty tubing materials in the industrial sector. Our company operates a complete PTFE tubing production line, delivering high-quality products from standard specifications to highly customized solutions.

PTFE tubing features the following key performance parameters
Continuous service temperature from -80℃ to +260℃, melting point 327℃, tensile strength ≥25MPa, elongation ≥300%, dielectric strength ≥26KV/mm, flame resistance VW-1, water absorption <0.01%, oxygen index >90%, and coefficient of friction as low as 0.04 (the lowest among all plastics).
Its six core advantages include
Our PTFE tubing production line adopts advanced extrusion molding technologies, featuring the following capabilities:
Precision extrusion molding using dedicated ram extruders and precision tooling, with accurate temperature control and sintering processes, achieving outer diameter tolerances within±0.06mm; multiple forming processes including paste extrusion (suitable for small-diameter thin-walled tubing), ram extrusion (for large-diameter thick-walled tubing), mandrel extrusion (ensuring uniform wall thickness), and multi-cavity extrusion (forming multiple lumens in one pass); an intelligent production line with automated controls and in-line monitoring, integrating laser micrometers and vision inspection systems for 100% full inspection; eco-friendly and energy-efficient processes with a condenser recovery system for lubricants; and full traceability with complete process parameter records for each batch.
PTFE tubing finds wide applications across multiple fields
In medical and pharmaceutical sectors for vascular intervention catheter liners, microcatheters, drug delivery systems;
In chemical and petrochemical industries for conveying highly corrosive media, acid/alkali/salt pipelines, waste acid treatment;
Excellent electrical insulation with a dielectric constant of only 2.0, ideal for high-voltage and high-frequency applications;
In electronics and electrical for wire insulation sleeves, high-frequency insulation components, transformer bushings, battery sleeves;
In aerospace for fuel and oil lines, hydraulic hose assemblies;
In semiconductor and new energy for high-purity chemical delivery, data center liquid cooling systems;
In food and beverage for FDA-compliant food-grade transfer tubing; in automotive for wire harness protection, sensor sleeves;
And in general industry for pneumatic tubing, fluid transfer equipment, and water treatment systems.
