PTFE (Polytetrafluoroethylene) Engineering PlasticPTFE (Polytetrafluoroethylene)

Low Friction, Chemical Resistant, Engineering Plastic

PTFE - a high performance, low friction, engineering plastic with exceptional resistance to a wide variety of chemicals. It is used in some of the most arduous industrial applications.

PTFE (polytetrafluoroethylene) is a material with several unique properties. It is manufactured using very specialised plant and process controls.

Smiths extruded PTFE rod is produced to BS EN ISO13000 and is ground to a plus tolerance, but with the option of tighter tolerances if required. Smiths’ standard stock range is made from virgin PTFE (not reprocessed) but several other application specific grades are available to order.


PTFE is a soft material but it can be machined into precise components. As with all fluoropolymer materials, care must be taken to avoid PTFE coming into contact with smoking materials. Full machining instructions may be supplied on request.

Chemical Resistance

Un-filled PTFE is inert to almost all chemicals. Attack is only evident from molten or dissolved alkali metals, and some fluorine compounds at higher temperatures. Some fluorinated refrigerants cause reversible swelling.
