Fluoroplastics
(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.
Key Features:
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.
Applications:
Food equipment, high purity semiconductor processing, chemical processing equipment, nuclear waste processing, seals, piston rings, gaskets, bushings, bearings, slide bearings.
Fabricating:
Machines easily, hard to bond.
Specifications Met:
PTFE meets FDA/USDA/Dairy 3A (natural resin), PVDF meets FM4910.
Special Grades:
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.
