PTFE Bushings
Solid PTFE bushings are made of a low-friction material capable of withstanding huge temperature swings, making it great for lot of indutrial applications.
PTFE's multifunctional properties allow it to be applied in diverse industries such as chemical, pharmaceutical, electrical, thermal & nuclear power plants, trains, manufacturing machine tools, etc. Literally all kinds of industries demand PTFE & find new applications because of their special and exceptional characteristics.
PTFE bushings are made of material with robust properties such as chemical stiffness, outstanding environmental tolerance, superb electrical insulator properties, heat resistance, non-adhesive characteristics, very low friction coefficient.
However because it is highly flexible, under heavy loads, PTFE bushings can crawl and twist. This theoretical downside can be reduced by adding a filler to the virgin PTFE for the bushings to take advantage of the properties of both materials.
Physically, the bushings of pure PTFE are both highly flexible and extremely dense. Chemically, the base material for the PTFE bushings is highly unreactive and insoluble and is therefore non-toxic, providing additional advantages in situations such as hospitals, pharmacy (e.g. as a catheter coating), and food production.
Fillers can also offer additional properties to the Virgin PTFE, including good heat dissipation, increased mechanical strength or thermal conductivity.
We are a PTFE & PTFE Filled Grade producer, retailer, and distributor. We can offer OVER 500 grades of PTFE.
Glass filler for PTFE is the most common filler material, but for certain uses certain materials offer other specific advantages. Such substitutes include iron, graphite, bronze, stainless steel, molybdenum disulfide, copper, and polyimide.
We offer any diameters of virgin PTFE and filled PTFE bushings from stock.
PTFE bushings - Virgin PTFE
PTFE bushings - Virgin PTFE The Virgin PTFE is an Extremely Multifunctional material with a wide variety of applications. The Virgin PTFE is one of the most chemically inert materials found which is used in many different sectors and applications in the form of PTFE bushings and PTFE thick wall tubes. With a wide range of applications, PTFE is an extremely versatile material. It has significant chemical resistance, a wide spectrum of temperature, is totally unaffected b..
PTFE bushings - 10% PEEK filled
PTFE bushings - 10% PEEK filled The offered filled PTFE bushings with PEEK are a high modulus material with excellent high temperature resistance. Excellent for back-up rings only. PEEK filled PTFE bushings contains of 90% PTFE virgin material and 10% PEEK. It is available in cream colour and comes in a hardness of 60 shore D. This material is comparable to PTFE Ekonol, but it is approved by FDA-CFR 21.177.1550, as well as FDA-CFR 21-177.2415 compliant and meets the 10/..
PTFE bushings - 15% Glass + 5% MoS2 Filled
PTFE bushings - 15% Glass + 5% MoS2 Filled This kind of PTFE bushings is filled with 15% Glass and 5% MoS2 Fillers. Often used together with glass or bronze, Molybdenum disulfide (MoS2) as a PTFE filler results in a more slippery and harder material. MoS2 also improves compression and wear resistance. MoS2 as one of the best known dry lubricants can improve surface strength and lower friction and wear rate coefficient, while the glass fibers provide structural stren..
PTFE bushings - 15% Graphite Filled
PTFE bushings - 15% Graphite Filled Graphite filled PTFE bushings offer some similar advantages to PTFE filled with 'normal' carbon but without the improved wear resistance. Graphite decreases the friction coefficient and PTFE bushings filled with graphite have excellent self-lubricating properties. PTFE graphite is available in dark gray color and has a hardness of 60 shore D. The compounds of these PTFE bushings are 15 percent graphite and 85 percent virgin PTFE. By ..
PTFE bushings - 25% Carbon Filled
PTFE bushings - 25% Carbon Filled Carbon-filled PTFE bushings benefit from increased compressive strength, decreased deformation during heavy loads, and greater tolerance to wear than virgin PTFE. Since carbon is conductive, it is ideal for PTFE bushings requiring higher thermal conductivity than PTFE itself, and because of its electrical conductivity it can become static dissipative. Carbon in the form of powder or fiber may be added. It may be abrasive, but not as muc..
PTFE bushings - 25% glass filled
PTFE bushings - 25% glass filled Adding glass to PTFE bushings makes it stronger and more durable, as well as reducing flexibility and likelihood of creep. Glass filled PTFE bushings can operate at the same temperature range as virgin PTFE and is similarly chemically inert. Glass has little effect on most of PTFE's electrical or chemical properties. It is resistant to acids and oxidation, but alkali can attack it. Glass in the form of short glass fibers is usually ..
PTFE bushings - 40% Bronze filled
PTFE bushings - 40% Bronze filled We are producer and distributor of these 40 percent Bronze Filled PTFE bushings. Bronze and PTFE additives enhance creep tolerance, thermal conductivity, and wear resistance while maintaining low friction properties. If good thermal and electrical conductivity is required in your application, bronze-filled PTFE bushings may be ideal. It also increases wear resistance by adding bronze to PTFE. Bronze, however, counteracts the PTFE's n..
PTFE bushings - 55% Bronze + 5% MoS2 filled
PTFE bushings - 55% Bronze + 5% MoS2 filled We are producer and distributor of these 55 percent Bronze and 5% MoS2 Filled PTFE bushings. Bronze and MoS2 as PTFE additives enhance creep tolerance, thermal conductivity, and wear resistance while maintaining low friction properties. 55% Bronze + 5% MoS2 filled PTFE has better wear, creep resistance, and higher thermal conductivity than glass fiber with PTFE. The compound is easily machined, but has good to average chemica..
PTFE bushings - Stainless Steel filled
PTFE bushings - Stainless Steel filled Stainless steel supplies high wear resistance and load bearing capability, along with better chemical resistance than bronze-filled PTFE. Stainless steel filled PTFE is especially good in steam service. PTFE receives increased strength and the ability to withstand loads by adding stainless steel material. PTFE bushings - Stainless Steel filled works great at higher temperatures, making PTFE filled with stainless steel a great o..
