What is Extruded PTFE Tubing?

Extruded PTFE Tubing is a specialized form of PTFE produced through the extrusion process. PTFE pellets are fed into an extruder and pushed through a die, forming the desired tubing shape. This method allows for the creation of uniform and seamless tubing, making it suitable for critical applications where precision matters.


Key Properties and Advantages

Extruded PTFE Tubing boasts remarkable characteristics that set it apart from other materials. Some of its key properties include:


1. High Heat Resistance

Extruded PTFE Tubing can withstand extreme temperatures ranging from -200°C to +260°C (-328°F to +500°F) without losing its structural integrity. This exceptional heat resistance makes it suitable for applications in harsh and demanding environments.


2. Chemical Inertness

PTFE is highly resistant to a wide range of chemicals, acids, and solvents, making it an ideal choice for industries dealing with corrosive substances. The tubing's inert nature ensures that it remains unaffected even when exposed to aggressive chemicals.


3. Low Friction Coefficient

One of the most famous properties of PTFE is its ultra-low coefficient of friction. This attribute makes Extruded PTFE Tubing an excellent choice for applications where smooth fluid flow is essential, such as in medical devices and industrial machinery.


4. Electrical Insulation
