PTFE tube and rod are semi-finished products manufactured from PTFE resin through molding, extrusion, or paste extrusion processes. PTFE is a synthetic fluoropolymer that offers a unique combination of properties — unmatched chemical resistance, wide operating temperature range, and the lowest coefficient of friction of any solid material.
Forms Available:
PTFE Tube (Hollow): Available in standard tubing, syringe tubing, convoluted tubing, and thick-walled pipe forms
PTFE Rod (Solid): Available in extruded rods (1-4mm, coiled) and molded rods (6-400mm)

A chlor-alkali production plant in Shandong, China, previously used titanium alloy pipes for transporting 90°C wet chlorine gas. However, severe corrosion issues caused the original pipeline system to require replacement approximately every 8 months, resulting in increased maintenance costs and production risks.
To solve this challenge, the plant replaced the titanium alloy pipeline with a PTFE-lined carbon steel pipe system. The PTFE lining provided a highly corrosion-resistant barrier against wet chlorine gas while maintaining the mechanical strength and cost advantages of carbon steel.
After installation, the PTFE-lined piping system has achieved over 5 years of continuous operation without leakage, significantly improving pipeline reliability, reducing downtime, and lowering long-term operating costs.
This successful application demonstrates the advantages of PTFE lining solutions in aggressive chemical environments where traditional metal materials face corrosion limitations.
A: PTFE tube is hollow, designed for fluid transfer, wire insulation, and applications requiring a passage through the center.
PTFE rod is solid, designed as a raw material for machining custom parts (seals, valve seats, bearings, bushings).
Quick rule:
Need to convey fluids or run wires through it → Tube.
Need solid material to machine into a custom part → Rod.
Both share the same chemical and thermal properties, the difference is form and function.
When to choose tube: Chemical transfer lines, wire insulation sleeves, heat exchanger tubing, medical fluid handling.
When to choose rod: Valve seats, piston rings, bearing pads, custom machined components.
Need both? We supply both, just send your requirements.
A: PTFE offers the broadest chemical resistance (pH 0-14), widest temperature range (-180°C to +200°C), and lowest friction (0.04). It is soft and creeps under load.
PEEK offers excellent mechanical strength and temperature resistance (-50°C to +250°C) but is much more expensive and has limited chemical compatibility.
Nylon offers good mechanical strength at low cost but has poor chemical resistance and moisture absorption.
Quick rule:
Need chemical resistance + low friction + wide temperature → PTFE.
Need high mechanical strength + high temperature → PEEK (cost is higher).
Need low cost + general mechanical parts → Nylon (chemical resistance is limited).
Send your application and we recommend the right material.
A: Temperature: -180°C to +200°C continuous service (filled grades up to +330°C).
Chemical: pH 0-14 universal resistance, NOT compatible with molten alkali metals or elemental fluorine at high temperatures.
Mechanical: PTFE is soft, deforms under sustained load (cold flow / creep).
Pressure: Tube positive pressure up to 1.6 MPa; vacuum up to 77 KPa.
Three common mistakes:
(1) Using virgin PTFE in high-pressure service: deforms under sustained load; use filled PTFE for improved creep resistance.
(2) Exceeding temperature limits: above +200°C, PTFE degrades and releases trace gases; for +300°C+ service, use filled grades with PPL additives.
(3) Incorrect tube wall thickness selection: for high-pressure fluid transfer, use thick-walled tube; for low-pressure or flexible applications, use standard wall.
We provide technical guidance with every order.
