Fluoro-Plastics offers modified PTFE basic shapes and machined parts. The new material offer engineering products with higher permeation resistance, lower creep, smoother surfaces and better high-voltage dielectric properties. Modified PTFE has the same performance characteristics of standard PTFE, viz. exceptional chemical resistance, high and low temperature capabilities, anti-stick performance and low friction.
Compared to standard PTFE modified PTFE displays remarkably enhanced performance characteristics. For example, the tensile strength and elongation of ordinary PTFE is 1500-2000 psi and 100-200%, whereas modified PTFE’s tensile strength is 4500 psi and its elongation at break is 500%. However, high voltage dielectric strength is where modified PTFE stands out: it is rated at 5200 volts per mil (at 1 mil), whereas standard PTFE is rated at only 500 volts per mil. In thicker sections the high voltage dielectric strength decreases, but not dramatically; Fluoro-Plastics offers modified PTFE which has been tested in 2.2, 3, 5, 8 and 10 mil thickness. The high voltage dielectric strength varied from slightly over 3,000 volts per mil at 2.2 mils to slightly over 2,000 volts per mil at 10 mils.
Also, parts and shapes made of modified PTFE can be assembled by heat welding and shaped by thermoforming. They can be joined without adhesives using moderate pressure in an oven, developing bonds with strength approaching that of the parts themselves. Welded sections can be subsequently thermoformed with no significant loss of strength. One of the simplest, most economical applications for modified PTFE is to make rectangular bags. A thin sheet can be folded over itself and heat sealed along two or three sides to make a bag for storing liquids and materials which must be protected from potential contaminants, e.g. in environmental or pharmaceutical sampling applications.
Fluoro-Plastics offers modified PTFE in skived sheets and rolls from one mil thick up to .125 inches thick, up to 48 inches wide, or slit to order. All rolls are packaged on a three inch cardboard core, or a three inch PVC core, to customer request.

Applications of PTFE & Teflon®
|
|
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..
Electrical applications: PTFE is one of the best insulators known. In thin sections, it will insulate to 500 volts per mil. There are grades if 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.
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 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 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.
