1 of 2 PTFE (Teflon ® ) Material Properties PTFE is a synthetic fluoropolymer of tetrafluoroethylene that finds numerous applications. PTFE is most well known by the DuPont brand name Teflon ® . PTFE has one of the lowest coefficients of friction against any solid. It is very non-reactive, partly because of the strength of carbon – fluorine bonds, and so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant, PTFE reduces friction, wear, and energy consumption of machinery. General characteristics: Maximum operating temperature of 260°C Very low coefficient of friction Food-safe Excellent insulator High resistance towards chemicals Technical Data Physical Properties Value Comments Density 2.3 g/cc D792 Water absorption, 24 hours < 0.01% D570 Mechanical Properties Value Comments Hardness, Shore D D55 D785 Tensile Strength 3,900 psi D638 Elongation at Break 300% D638 Tensile Modulus 80,000 psi D638 Flexural Modulus 72,000 psi D790 Flexural Strength No Break D790 Compressive Strength 3,500 psi D695 Compressive Modulus 70,000 psi D695 Izod Impact, Notched 3.5 ft-lb/in D256 Coefficient of Friction 0.056 -
