PTFE & Teflon® is used extensively in many
different industries:
PTFE : Teflon of 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..
PTFE : Teflon of Electrical
applications:
PTFE is one of the best insulators known. In thin sections,
it will insulate to 500 volts per mil. There are grades of PTFE 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 shape of choice where
machining or drilling long lengths to close tolerances is impossible.
Multi-hole tubing can be extruded. PTFE can be machined into standoff
insulators, and many different types of high voltage encapsulation
devices for electrical components.
PTFE : TEflon of 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.
PTFE : Teflon of 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.
PTFE : Teflon of Laboratory
applications:
PTFE piping, tubing and vessels are used in various
laboratory ware because of their chemical resistance, and inertness. No
contaminants adhere to the surface.
PTFE : Teflon of 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 base resin to
enhance certain properties, e.g. glass fiber, glass bead, carbon,
graphite, molybdenum disulfide, bronze, etc.
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.
