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 260°C 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.

Reprocessed PTFE – Reprocessed PTFE is made from recycled material.

Tech Tip – PTFE can be used at any temperature from -200°C to +260°C
