Of all the known plastics, PTFE parts has some remarkable properties: it will not attacked by corrosive


acids, even if they were hot; it did not dissolve in solvents; it could be cooled to -180°C without becoming


brittle and it could be heated to 260°C without impairing its performance. PTFE materials also are


extremely stable and nonflammable; clean, dry, non-oily and non-staining. The material is biologically


inert and does not support biological growth (that is, it is non-pyrogenic). PTFE offer an extremely low


static coefficient of friction, which stems from the extremely low intermolecular forces in the PTFE


molecule itself.


Apparent Density: 2.1 ~ 2.3 g/cm3


Tensile Strength: ≥ 14.0 Mpa


Ultimate Elongation: ≥ 140%


Temperature: -20° F to 500° F (-180°C to 260°C)
