PTFE is used extensively in many different industries:
Petrochemical and chemical processing: PTFE is the material of choice for
gaskets, vessel linings, pump interiors, washers, rings, seals, spacers, dip tubes and well-drilling
components because it is corrosion resistant and chemically inert; it is unaffected by virtually all
acids and caustics and functions in environments to 500 degrees F..
Semi-Conductor Industry: PTFE is inert, and its operating temperature
range is from minus 350 degrees Fahrenheit to 550 degrees Fahrenheit. When made to ultra pure standards
it is the material of choice for various items used in chip manufacturing, including encapsulation
devices for quartz heaters, and the like.
Food, Beverage and Pharmaceutical industries: Virgin PTFE is approved by
the Food and Drug Administration for use in the food, beverage, cosmetics and pharmaceutical industries.
Thin Film and sheets make an inert, no-toxic slide surface without microscopic depressions where
microbes can grow. Conveyancing components - profiles, guide rails and slides - can withstand high
temperatures inside baking and drying ovens and other heated segments of the food, cosmetics or
pharmaceuticals manufacturing processes.
Laboratory applications: PTFE piping, tubing and vessels are used in
various laboratory ware because of their chemical resistance, and inertness. No contaminants adhere to
Bearing pads: Glass filled PTFE can be cut or stamped into bearing pads,
and will resist all weather-related degradation while remaining an inert interface between disparate
construction materials, like steel and concrete.
PTFE Compounds: Various fillers can be blended with the PTFE base resin to
enhance certain properties, e.g. glass fiber, glass bead, carbon, graphite, molybdenum disulfide,
PTFE does not melt; it cannot be molded into complex shapes, but must be machined. PTFE is
easily machined using standard mechanical woodworking and stamping equipment and tooling. Most shapes
are sold slightly oversized for easy trimming and machining to exact sizes.
