Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene
that finds many applications. The most well-known brand name of PTFE is PTFE
by DuPont Co.Polytetrafluoroethylene (PTFE) shows a extraordinary 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 fire-resistant and may
be used up to 260ºC. PTFE's coefficient of friction is very low and it shows the effect
of self lubrication with stable mechanical properties which makes it mostly 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 conditions.
Product Features:
