Extruded PTFE Tube
Extruded PTFE tubes are flexible hollow sections with a high working temperature range, low coefficient of friction, and superior thermal resistance. Using an unconventional PTFE tube extruder, the final tubing is inherently chemically inert with excellent weathering resistance.
Over the years, PTFE paste extrusion and PTFE ram extrusion remain the most effective way to manufacture extruded PTFE tubes. Additionally, paste extrusion produces flexible extruded PTFE tubing. However, the paste extrusion only allows for a limited continuous length.

During the PTFE ram extrusion process, polytetrafluoroethylene is heated to sintering temperature, where the plunger or ram make Teflon extruded tubing through the die. The extrusion process allows for the manufacturing of continuously extruded PTFE tubes.
The extruded PTFE tubing comes with varying internal and external diameters, for the dynamic needs in most applications. Even the thin wall extruded tubing can withstand elevated temperatures while maintaining superior chemical and physical properties.
Besides, extruded PTFE tubes are known for tight dimensional tolerance. Remember, extruding PTFE tubes producees tubing with uniform thickness throughout the entire structure.
Applications of Extruded PTFE Tube
Where to use extruded PTFE depends on the material grade take for example:
- Medical applications or machines such as Softgel encapsulating machines require extruded tubing made from virgin PTFE
- Machine feeding tubes such LSR injection molding may use machine-grade PTFE
- Chemical industries may use filled PTFE material
