PTFE

Low friction engineering plastic with outstanding chemical, high temp, and weathering resistance

PTFE (polytetrefluoroethylene) is a soft, low friction fluoropolymer with outstanding chemical  and weathering resistance. PTFE is stable at temperatures up to 500oF and it is often used in high temperature environments. PTFE also has excellent electrical insulating properties.

PTFE is available in a variety of formulations including unfilled, glass-filled, bearing, and FDA compliant grades.

PTFE MATERIAL OPTIONS

Virgin (Unfilled) Grade PTFE– Unfilled PTFE, made from virgin PTFE resin, is extremely soft and formable and it is often used for chemical resistant seals and gaskets.

Glass-Filled PTFE– Glass-filled PTFE has enhanced strength and stiffness. 


Bearing Grades of PTFE– Bearing grades of PTFE have extremely low friction and high service temperatures. They are frequently specified for high performance bearings and bushings, particularly in applications that require resistance to corrosive chemicals. 


Reprocessed PTFE– Reprocessed PTFE is made from recycled material.

Tech Tip– PTFE can be used at any temperature from -328°F (-200°C) to 500°F (+260°C)
