Applications of PTFE Tubes
PTFE tubes are typically used to reduce resistance and guide filament in filament-feeding systems, extrusion heads and other guided-feed applications where low friction and chemical inertness are important. Teflon's combination of a low coefficient of friction, broad thermal stability and high chemical resistance makes it a common choice for polymer feed paths, insulating bushings and non-reactive fluid or gas routing in industrial processes.
PTFE may be less suitable where high mechanical load, abrasive wear or dimensional rigidity are required, due to its limited wear resistance and tendency to creep under sustained stress; in those cases harder polymers or metal liners are often preferred. Available variants are described in the ptfe collection.
