Polytetrafluoroethylene (PTFE / Teflon)

Polytetrafluoroethylene (PTFE) shows a remarkable chemical resistance and it is insoluble in all known solvents. It is attacked only by molten alkali metals and by fluorine at high temperatures. PTFE is incombustible and may be used up to 260°C (300°C for short periods). PTFE’s coefficient of friction is extremely low and it shows the effect of self lubrication with constant mechanical properties which makes it particularly suitable for bearings, joints, O-rings, stirring bars, hazardous materials bottle pouers, syringes, crucubles, evaporating dishes etc. PTFE may be shaped by compression and sintering into bottles and beakers where its chemical stability and non-wettability make it suitable for use in extreme circumstances.
