PTFE (Polytetrafluoroethylene)

Teflon® trade name of DuPont

KEY FEATURES

Excellent chemical resistance, wide temperature range – 350 F to 500 F continuous, slippery, lowest coefficient of friction, excellent electrical insulator, poor mechanical properties unless fillers are added

APPLICATIONS

Gaskets and spacers, valve components, blades, seals, piston rings, bushings, bearings, slide bearings

FABRICATION

Machines and cuts easily, die cuts and stamps (thinner gauges)

GRADES

Unfilled PTFE

Glass filled – higher mechanical properties

Mechanical grade – less expensive, lacks resin purity, conductive
