PTFE
Polytetrafluorethylene
PTFE, most well known under the brand name Teflon, is the most well known fluoroplastic and has the lowest coefficient of friction among all solid materials. The material is resistant to virtually all chemicals and has an extremely wide temperature range from -200 °C to +260 °C. PTFE is non-stick, FDA approved and has excellent electrical insulation. The material is used for seals, gaskets, slide rails and chemically resistant components. PTFE has lower mechanical strength than most other plastics, but compensates with its unique combination of chemical resistance and low friction.
