(PTFE, PVDF (Kynar®, Solef®), Rulon®, FEP, ETFE, Tefzel®, PCTFE Kel-F®, Neoflon™ CTFE)
A class of parraffinic polymers with some or all of the hydrogen replaced with fluorine.
Excellent chemical resistance, low coefficient of friction and high wear, high and low temperature resistance -400 °F to 500 °F, resistance to weathering, good electrical properties.
Food equipment, high purity semiconductor processing, chemical processing equipment, nuclear waste processing, seals, piston rings, gaskets, bushings, bearings, slide bearings.
Machines easily, hard to bond.
PTFE meets FDA/USDA/Dairy 3A (natural resin), PVDF meets FM4910.
PTFE – excellent chemical resistance, lowest coefficient of friction, Wide temperature range -400 °F to 500 °F (-240 °C to 260 °C), Excellent thermal and electrical insulation properties. Fillers added to improve strength (ex. glass, carbon, bronze), for example Rulon®-filled PTFE.
PVDF – (Kynar® , Solef®, temperature range -80 °F to 300 °F (-62 °C to 149 °C) Better mechanical properties than other fluoroplastics, but not as slippery, chemical resistant and electrically insulating.
FEP – fluorinated ethylene propylene lower temperature 400 °F and not as slippery. Better clarity than other flouroplastics. Multiple fillers can improve strength and lower coefficient of friction.
ETFE – Tefzel® greater strength and stiffness than PTFE, FEP and PFA and excellent impact strength, temperature continuous 300 °F
PCTFE – KEL-F® polychlorotrifluoroethylene temperature range – 400 °F to 300 °F, High compressive strength, low deformation under load, low gas permeability, low flammability and zero moisture absorption, high optical transparency.
