FAQs About PTFE Tube
What is the maximum temperature a PTFE tube can withstand?
PTFE tubes can continuously operate at temperatures up to 260°C (500°F) and briefly withstand peaks up to 300°C (572°F) without degrading, making them ideal for high-heat applications.
Are PTFE tubes resistant to all chemicals?
PTFE tubes exhibit excellent resistance to most chemicals, including strong acids, bases, and organic solvents. However, they may not be suitable for use with molten alkali metals or certain fluorinated compounds at high temperatures.
Can PTFE tubes be used for food contact applications?
Yes, PTFE is FDA compliant and often used in food processing and medical devices due to its non-toxic, non-stick, and easy-to-clean properties, ensuring safety and hygiene.
How do I choose the right wall thickness for my application?
Wall thickness selection depends on pressure requirements, flexibility needs, and chemical exposure. Thicker walls offer higher pressure ratings but reduced flexibility, while thinner walls are more bendable but suited for lower pressures.
Is PTFE tubing flexible or rigid?
PTFE tubing is semi-rigid and maintains its shape well, but it can be bent and flexed without kinking, especially in thinner wall variants, providing a balance of durability and maneuverability.
Does PTFE tube have any electrical properties?
PTFE is an excellent electrical insulator with high dielectric strength, low dielectric constant, and low dissipation factor, making it perfect for wiring, capacitors, and other electronic applications.
How is PTFE tubing manufactured?
PTFE tubing is typically produced through extrusion processes, where fine powder is compressed and sintered at high temperatures to form a continuous tube, ensuring consistent dimensions and properties.
Can PTFE tubes be custom-colored?
Yes, custom colors are available by adding compatible pigments during manufacturing, though natural white is standard. This is useful for coding or aesthetic purposes in various industries.
What is the shelf life of PTFE tubing?
PTFE tubing has an virtually indefinite shelf life when stored in a cool, dry place away from direct sunlight and extreme temperatures, as it does not degrade or become brittle over time.
Are there any alternatives to PTFE tubing?
Alternatives include FEP, PFA, or silicone tubing, but PTFE offers superior temperature and chemical resistance. The choice depends on specific application requirements like flexibility or cost.
Additional Technical Details
For specialized applications, our PTFE tubes can be reinforced or lined with other materials to enhance performance. Custom sizes and certifications (e.g., USP Class VI for medical use) are available upon request. Always consult technical datasheets for precise compatibility and performance data.

25% Bronze Powder Filled Teflon PTFE Tube
The addition of Bronze to 25% Bronze Powder Filled Teflon PTFE Tube better dimensional stability and lowers creep, cold flow and wear. It increases hardness and compressive strength whilst also increasing thermal and electrical conductivity
Graphite Filled PTFE Tube
Graphite Filled PTFE Tube has exceptional chemical resistance to corrosive environments and it is compatible with most hydraulic fluids. PTFE. Graphite Filled exhibits good initial wear and rubbing/sliding characteristics in dry and water applications. Excellent performance when used for hydraulic or pneumatic compression type rod and piston seals, bearing bands and rotary applications. Graphite is commonly blended with carbon and PTFE (Teflon)
Bronze Powder Filled PTFE Tube
The addition of Bronze to Bronze Powder Filled PTFE Tube better dimensional stability and lowers creep, cold flow and wear. It increases hardness and compressive strength whilst also increasing thermal and electrical conductivity
Carbon Fiber Filled PTFE Tube
Carbon Fiber Filled PTFE Tube has good chemical resistance to corrosive environments, has better creep and wear resistance compared to standard PTFE materials. These properties are improved with the addition of a carbon filler. This filler improves dimensional stability, raises the heat deflection temperature, improves creep resistance and the dynamic bearing performance. PTFE Carbon Filled exhibits good initial wear and rubbing/sliding contact characteristics in both dry and wet/water applications. It is frequently used in piston rings to reduce cylinder wall wear by entrapping abrasive foreign particles in their relatively soft surface
5% Glass Fiber Filled PTFE Tube
Glass fibre is used as a 5% Glass Fiber Filled PTFE Tube as it offers much improved compression and wear properties. The material may also be inert gas sintered to further improve creep properties and reduce porosity and gas permeability (there would be a consequent loss of tensile properties).
Molded PTFE Tube
Molded PTFE Tube can be made into non-standard parts by mechanical working, also it can be used as non-sticking materials. It can be used at the temperature of -180℃~+260℃. It has the lowest frictional factor and the best anti-corrosive property among the known plastic materials.
