Petrochemical and chemical processing:
PTFE Teflon 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..
Electrical applications:
PTFE Teflon is one of the best insulators known. In thin sections,
it will insulate to 500 volts per mil. There are grades of PTFE
Teflon which have even greater dielectric strength. It is frequently
used in wire and cable wrap, and to separate conductive surfaces in
capacitors. Thick walled close-tolerance extruded tubing is the PTFE
Teflon shape of choice where machining or drilling long lengths to
close tolerances is impossible. Multi-hole tubing can be extruded.
PTFE Teflon can be machined into standoff insulators, and many
different types of high voltage encapsulation devices for electrical
components.
Semi-Conductor Industry:
PTFE Teflon 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 Teflon 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 Teflon Hose, tubing and vessels are used in various laboratory
ware because of their chemical resistance, and inertness. No
contaminants adhere to the surface.
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 Teflon Compounds:
Various fillers can be blended with the PTFE Teflon base resin to
enhance certain properties, e.g. glass fiber, glass bead, carbon,
graphite, molybdenum disulfide, bronze, etc.
PTFE Teflon does not melt; it cannot be molded into complex shapes,
but must be machined. PTFE Teflon® 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.
