    • PTFE (PolyTetraFluoroEthylene), it is a fluorocarbon-based polymer that exhibits astonishing chemical resistance and ultra high-purity. Self-lubricating and with a low friction coefficient, PTFE is suited for the manufacture of high-temperature seals, insulators and bearings used in semiconductor, aerospace & chemical processing industries. PTFE's mechanical properties are low compared to other plastics, and can be used over a wide temperature range of -100°F to +400°F (-73°C to 204°C). Mechanical properties are often enhanced by adding fillers. It has excellent thermal and electrical insulation properties and a low coefficient of friction. PTFE is very dense and cannot be processed by melting. PTFE must be compressed and sintered to form useful shapes.
    • PTFE heat shrink tubing (PTFE) is available in 2:1 and 4:1 shrink ratios, and is widely used in military applications (MIL-I-23053/12) because of its high continuous use temperature (250°C), and outstanding chemical resistance.
    • PTFE heat shrink tubing is the most difficult of the three fluoropolymer materials to shrink due to its extremely high shrinking temperature (325-340°C). You can use a heat gun or welding torch to shrink PTFE, but these methods have a tendency to cause the material to overheat in small areas, while under-heating other areas, causing uneven shrinking and potential burning of the material. The most reliable method for shrinking PTFE Teflon is the use of a controlled temperature oven; however this is impractical with large harnesses or temperature sensitive components.
    • PTFE heat shrink tubing is available in a 2:1 shrink ratio and 4:1. The 2:1 is available in up to four different wall thicknesses. Please note: when ordering our 2:1 PTFE Heat shrink, ORDER AS SIZE AFTER SHRINKING.
    • Etched PTFE
      PTFE is an amazing non-stick material, but what about when you need to glue it to the suface of another material ? In order to bond standard PTFE to another surface such as stainless steel, a process called "etching" is required. Typical applications would include the lining of chemical process tanks or other equipment used in caustic environments. When bonding is needed, sodium ammonia etching is usually the most economical answer. This process uses of a mixture of sodium and ammonia that is formulated to create a bondable surface both quickly and efficiently. Sodium/ammonia etching service complies with all applicable commercial, military & federal specifications for the surface treatment of all fluoropolymers including: PTFE, PFA, FEP, ETFE, PCTFE, PVDF, PVF, & ECTFE.
      From microchips to full size rolls, fluoropolymers of any shape or complexity, including tape, sheet, tubing, molded shapes & machined parts of any configuration can be etched & bonded. This treatment can be accomplished on one or more surfaces, or selectively within close tolerances.
    • Note: Etched surfaces will discolor to a brown appearance.
    • May be Etched on One Side (EOS)(Standard) or Two Sides (E2S)
    • PTFE Glass-Filled - Milled glass fibers have the least effect on chemical and electrical properties and add greatly to the mechanical properties of unfilled PTFE.

    • Note: Please allow 4-5 weeks standard delivery time for this product.
    • PTFE (PolyTetraFluoroEthylene) PTFE is a fluorocarbon-based polymer that exhibits astonishing chemical resistance and ultra high-purity. Self-lubricating and with a low friction coefficient, PTFE sheets and rods are ideally suited for the manufacture of high-temperature seals, insulators and bearings used in semiconductor, aerospace & chemical processing industries. PTFE's low coefficient of friction makes it suitable for applications where sliding action of parts is needed: such as plain bearings, gears, and slide plates. In these applications, it performs significantly better than nylon and acetal; and is comparable to UHMW. PTFE however can be used over a far wider temperature range than these materials; -100°F to +400°F (-73°C to 204°C) and offers superior electrical insulation properties. Although its' mechanical properties are low compared to other engineering plastics, those properties can be enhanced through the use of additives such as Carbon, Graphite, Bronze, and Glass Fiber.

PTFE must be compressed and sintered to form useful shapes.
    • PTFE fillers don't act like elastomer fillers, which become chemically bonded to the elastomer. With polytetrafluoroethylene, the high shear modulus fillers are encapsulated and bound by the low shear modulus PTFE.
      Here's an overview of PTFE fillers:
    • Glass is the most common filler for PTFE. Widely used in hydraulic piston rings, glass gives good wear resistance, low creep, and good compressive strength. Glass also has excellent chemical compatibility. The major disadvantage is that glass-filled PTFE compounds are abrasive to mating surfaces, especially in rotary applications.
    • Molybdenum disulfide (MoS2) improves wear resistance and further lowers the coefficient of friction. ôMoly" is typically combined with other fillers (such as glass and bronze).
    • Carbon (powder or fiber) imparts excellent compression (low deformation under load) and wear resistance, good thermal conductivity (heat dissipation), and low permeability. Carbon-filled PTFE compounds are not as abrasive as glass-filled compounds, but they are still more abrasive than polymer-filled compounds. Carbon-filled compounds have excellent wear and friction properties when combined with graphite. Carbon fiber lends better creep resistance than carbon powder, but fiber is more expensive.
    • Graphite is a crystal modification of high purity carbon. Its flaky structure imparts excellent lubricity and decreased wear. Graphite is often combined with other fillers (especially carbon and glass).
    • Bronze (a copper-tin alloy) lends excellent wear resistance and thermal conductivity. Bronze-filled materials have higher friction than other filled PTFE compounds, but that can be improved by adding moly or graphite. Bearing and piston ring applications often use compounds containing 55% bronze – 5% moly. Bronze-filled compounds have poorer chemical resistance than other PTFE compounds.
    • Stainless steel supplies high wear resistance and load bearing capability, along with better chemical resistance than bronze-filled PTFE. Stainless steel is especially good in steam service.
    • Wollastonite (calcium silicate) is a mineral filler giving properties similar to glass (minus the abrasiveness). The FDA has approved it for food service.
    • PPS (polyphenylene sulfide, trade name Ryton®) was the first polymeric material used to improve PTFE's wear and abrasion properties. PPS-filled compounds also exhibit excellent deformation and extrusion resistance, making them good for use in back-up rings.
    • Ekonol® is a thermally stable aromatic polyester. When blended with PTFE, it produces a composite material with excellent high temperature and wear resistance. Ekonol® will not wear mating metal surfaces, making it good for rotary applications. Ekonol®-filled materials are also good for food service.
    • Polyimide is another polymeric filler offering superior wear and abrasion resistance. Polyimide-filled PTFE compounds have about the lowest friction properties of all filled PTFE materials, so they provide great performance in non-lubricated (dry) applications. They will not abrade mating surfaces (even soft materials such as brass, stainless steel, aluminum, and plastic). Polyimide is one of the most expensive PTFE fillers, however.

      Other fillers include calcium fluoride (CaF2), which is specifically used in hydrofluoric acid (HF) service, and alumina (Al2O3), which can improve the mechanical properties of compounds destined for high voltage applications. Alumina-filled compounds are very abrasive.
    • PTFE Balls (Polytetrafluorethylene) Balls. - PTFE is a non-friction material which is resistant to most corrosive agents and is electrically nonconductive. PTFE is particularly suitable for use in apparatus designed to handle cryogenic liquids and acids. Commonly used in ball seal valves.
    • PTFE O-Rings are available from Professional Plastics.
      PTFE is a popular O-Ring material which is White in color. The PTFE O-Rings are popular for use in applications which require a chemically resistant and non-compressible material. PTFE is the chemically inert of the O-ring materials. It is resistant to most chemicals including acids, bases, oils, steam and other chemicals. It is also very tough and abrasive resistant. However the material is not easily compressed, and therefore may not seal as easily as some of the other polymers. Its outstanding tear resistnace and abrasive resistance result in its slippery surface properties that make it advantageous for use in seals in moving systems such as mass spectrometer probes and valves.

      O-Rings are available in sizes (sizes 0, 1, 2 and 3) which correspond to the diameter of the cross section of the O-Ring. Within these groups the O-Rings are classified according to their inside diameter.
    • Size 0 = Nominal Width of 0.062" (actual width = 0.070")
    • Size 1 = Nominal Width of 0.093" (actual width = 0.103")
    • Size 2 = Nominal Width of 0.125" (actual width = 0.139")
    • Size 3 = Nominal Width of 0.187" (actual width = 0.210")
    • PTFE - Bronze Filled - This filler has better wear, creep resistance, and higher thermal conductivity than glass fiber with PTFE. The compound is easily machined, but has poor chemical resistance in the presence of acids and alkali. Bronze-filled PTFE is useful in applications which undergo high mechanical loads or high-speed rubbing contacts where the bronze filler supplies the strength and conductivity to carry away excess, unwanted heat.
    • PTFE miniature beading (Small diameter PTFE Rod Coils) exhibit astonishing chemical resistance and ultra high-purity. Self-lubricating and with a low friction coefficient, PTFE (polytetrafluoroethylene) beading is basically very small diameter rod in coils. PTFE is ideally suited for the manufacture of high-temperature seals, insulators and bearings used in semiconductor, aerospace & chemical processing industries.
    • Diameter Range: 0.28" to .150"
    • 1/16'', 1/8" & 1/4" PTFE Ferrules - PTFE ferrules have an upper temperature limit of 250° C. Ferrules have precision-drilled IDs so there are no mold imperfections. The one-piece design does not require a back ferrule. PTFE is completely inert and does not stick to glass. Ferrules come in standard 10 piece packages except as noted. Please note for all ferrules: 0.3mm ID ferrules fit 0.18mm ID and narrower capillary columns 0.4mm ID ferrules fit 0.25mm ID capillary columns 0.5mm ID ferrules fit 0.32mm ID capillary columns 0.8mm ID ferrules fit 0.53mm ID capillary columns "Straight" ferrules are used for 1/16" OD tubing
    • Unsintered PTFE (polytetrafluoroethylene) film provides the inherent design features of ordinary sintered PTFE including exceptional chemical resistance, a temperature range of –450 F through +500 F, extremely low coefficient of friction and a non-stick surface, with the added advantages of greater conformability and a superior seal once it is incorporated into an assembly matrix and sintered in place. Used primarily as electrical insulation in wire and cable applications, unsintered PTFE is used for cable insulation, harness wrap and as the dielectric medium in coaxial lines. The material is also well suited for use in gaskets, expansion joints, valve seals/seats and diaphragms. Unsintered PTFE drapes over and fits the most complicated shapes, allowing it to fill the tightest corners and match the sharpest edges. Since this polymer is fibrillated the material possesses excellent tensile strength (2000 PSI nominal – on 2 mil material), concerns regarding line breakage during end-product manufacturing are alleviated.
    • Carbon-Filled PTFE was developed for its mechanical properties. The two basic materials used in these compounds, by themselves, are very questionable. PTFE has good frictional properties including low wear rates and good elasticity. The carbon filler is brittle and has low wear properties. Both fail at high loads and increased velocities. When both elements are formulated and properly blended together, they become an extremely good material for use as seals and rings in the reciprocating compressor industry. The properties increase several hundred times. Wear resistance is changed dramatically compared to Virgin PTFE. The type and percentage of carbon is critical to material performance. Carbon filled has a higher percentage of filler than any other PTFE blend. Therefore the two materials must be similiar in size to prevent voids in the molded billet. For optimum wear properties, the filler percentage is also important. Lower percentages are easier to machine but do not perform as well in service. AVA56 PTFE material, is designed for optimum wear properties in all suitable applications.
      The molding cycle is also important to provide proper pysical properties. At higher molding pressures the material has higher density and more filler is required. Not all carbon filled PTFE is of the same quality.
