Manufacture, Properties, and Application of Teflon Fiber

Manufacturing process, physical and chemical properties of Teflon fiber, and its industrial application.
Keywords: PTFE fiber ‚Teflon ‚Manufacturing ‚Physicochemical properties ‚Application

In 1938, chemists at DuPont Laboratories discovered that tetrafluoroethylene (CF2 CF2) gas polymerized into a waxy, insoluble, infusible powder, and had some potentially useful properties of a new type of plastic, which had been used for the first time. Anatomic bomb of uranium was refined, and by 1946 tetrafluoroethylene was widely used, although its production was limited. Until 1950, when DuPont mass-produced and brought it to market under the brand name Teflon, Teflon soon became synonymous with heat resistance, chemical resistance and low friction. Teflon was first known as a resinous material, later developed into a fiber material, and put on the market in 1954, expanding many new application areas, especially in high-temperature chemical environments. ISO (International Standards Organization) calls Teflon fiber fluorite fiber (Fluo-fiber). Due to the high price of this fiber, it is mainly used in high-performance technical textiles and also in high-end clothing fabrics.

Polytetrafluoroethylene (PTFE) consists of a chain of carbon atoms fully saturated with fluorine atoms. The large number of fluorine atoms “bonds very strongly to the carbon atoms, and the fluorine atoms surround the carbon atoms in a regular, tightly packed fashion” forming a protective screen. PTFE molecules have no polar force and cannot be combined with fiber molecules such as nylon and polyester. PTFE is a non-polar linear crystalline polymer with a molecular weight of 500,000 to 200,000, a specific gravity of 2.28 to 2.29 (23°C), a melting point of 327°C, and a decomposition temperature above 415°C.

Teflon can be made into resins, powders, flakes and fibers and other products. Teflon in fiber form is a long-chain polymer with high tensile and compressive strength. Because of its stable and strong molecular structure, it has a relatively high density (2.2g/cm3) and unique physical, thermal and chemical properties, which can be used in fields where general fibers are not suitable. Teflon fibers have a circular cross-section and can be used to manufacture multifilament, staple and linters of various linear densities, filament linear densities and staple lengths. Teflon fibers can be carded, brushed, woven, woven and knitted into fabrics and are available in dark brown or pure bleached white.

Teflon is a polymer with fluorine as the main component. Although fluorine is a highly volatile and highly reactive

physical properties
1 Thermal stability
Teflon is stable at continuous operating temperatures up to 260°C and can withstand transient high temperatures up to 290°C. Because of its unique molecular structure, it is difficult to melt at high temperatures. When the temperature is as high as 290°C or more, the sublimation begins, and the weight loss rate is only 0.02%/h; when the temperature is as high as 327°C, the gel state is reached. Teflon fibers are less ductile at low temperatures, but have also been found to be very durable, as low as -268°C in some applications.
2 UV resistance
Teflon fiber has strong resistance to direct sunlight. Three years of direct exposure to sunlight and the atmosphere showed that “the breaking strength was reduced by only 2%.
3 Friction performance
The sliding friction coefficient of Teflon fiber is small, the smallest among the known fibers, about 1/6 of that of nylon fiber, so it can be used in applications requiring maintenance-free, non-adhesive and easy sliding properties. The coefficient of friction of Teflon fiber maintenance-free bearings has been measured to be only 0.08, and its dynamic coefficient of friction decreases with increasing load or temperature.
4 Conductivity, tensile and shrinkage properties
Teflon has low conductivity and is an excellent electrical insulating material. It has a particularly important use value in the continuous high temperature environment of 175 ℃ ~ 290 ℃. Its elongation at break is 19% (30% for Teflon resin), its tensile strength is moderate, about 1∙372cN/dtex, and it is not affected by humidity. Teflon has a potential shrinkage of up to 25% at a temperature of 30°C, a property that is very important for fabric heat-setting or heat-setting processes.

chemical properties

The main advantage of Teflon fiber is its unique chemical resistance, including all known acids, alkalis, halogens and oxidants. It has the highest chemical resistance of any commercial organic fiber, even at high temperatures. At present, only some perfluorinated organic solvents have been found to dissolve Teflon fibers, but at temperatures above 29°C. Although Teflon fibers can be bleached, they cannot be dyed due to their tight molecular structure and resistance to water and solvents. The fibers themselves are not toxic, but may release toxic fumes at high temperatures.

DuPont’s Teflon fibers are used in a variety of industries, and their low friction, thermal and chemical properties can solve many design challenges. The properties of Teflon fibers differ significantly from those of the corresponding polymeric resins, which may be well-known for their use as nonstick surface compounds, but which have better tensile strength and deformation resistance than the latter.

Bearings and low friction components

Bearings, bearing housings and other engineered components are the main applications for Teflon filaments and fabrics. Products made from Teflon fibers offer the advantages of maintenance-free, low friction, heat, chemical resistance, and long service life, making them ideal for high-load, intermittent or slow-running drive systems. Teflon fibers can also be incorporated into thermoplastic, heat-set and elastomeric resins to create better-performing injection-molded plain bearing surfaces. An example is Delrin AF from DuPont, which consists of an acetal resin containing Teflon fibers.

Ordinary plain bearings containing Teflon fibers were mainly used in high-tech industries in the past, but are now widely used in conventional industries where high-load, maintenance-free, small and light bearings are required. For example, the use of Teflon fiber bearings can achieve the design goal of reducing space. In addition, Teflon fiber also has the characteristics of non-lubrication, durability and good environmental adaptability.

The automotive industry uses low-friction and deformation-resistant Teflon fibers to manufacture automotive window guides, which have better sliding properties, thereby making window lift motors smaller and less expensive. Some car chassis have Teflon fibers on the surface to eliminate noise and extend the life of the car

Teflon fiber bearings are used in food processing machinery to ensure food hygiene to a large extent and eliminate lubricating oil contamination. Based on the same considerations, this bearing can also be used in labeling machines. Food conveyor belts woven from bleached Teflon fibers are hygienic and non-stick to food. The bleached fiber has been approved by the US FDA, its chemical properties are stable, and the temperature range is from minus to 260℃.

As mentioned above, Teflon is a new type of special fiber. Has special excellent physics.

Polytetrafluoroethylene (PTFE) fabric is a composite material consisting of PTFE, fabric or aramid fiber, among other components. It is crafted through specific weaving methods and undergoes specialized impregnation treatment. This results in a fabric known for its high strength and low friction coefficient. When used in spherical plain bearings, this fabric not only retains the bearings’ high-load bearing and self-aligning properties but also adds the benefits of self-lubrication, impact resistance, and extended lifespan. These self-lubricating bearings are highly applicable in advanced fields such as aviation and aerospace, particularly in critical load-bearing areas.

Keywords: PTFE Fabric, Liner Application, Self-Lubricating Spherical Plain Bearings

Self-lubricating spherical plain bearings are essential in numerous cutting-edge technological fields. The performance of the self-lubricating materials is crucial in ensuring that these bearings can handle heavy loads, resist impacts, and have a long service life. PTFE fiber fabric, as a novel polymer material, offers excellent toughness, high strength, and low friction, making it an ideal material for bearing lubrication layers. This paper briefly introduces the use of this material in spherical plain bearings.

Polytetrafluoroethylene Fiber Fabric:

This fabric is a blend of PTFE fibers and other fibers, woven into a double-layer fabric with various textile structures like plain, twill, or satin. The fabric’s surface, rich in PTFE fibers, serves as the low-friction contact surface. The other side, composed of high-strength bonding fibers, forms the bonding surface. This dual-layer structure utilizes the low friction of PTFE and the high strength of the fibers, often reinforced with materials like Kevlar, aramid, glass, or carbon fiber.

Performance of PTFE Fiber Fabric:

PTFE fabric’s friction surface creates a solid lubricating film capable of enduring extensive friction cycles. The fabric’s friction coefficient is remarkably low, even lower than that of molybdenum disulfide and graphite. When in contact with metal, the heat generated reduces the shear strength of PTFE, enabling it to adhere to the counter-abrasive surface and form an effective lubrication layer. Additionally, the fabric boasts high load-bearing capacity, wide temperature tolerance, excellent corrosion resistance, and strong bonding fastness due to impregnation treatment.

Application in Spherical Plain Bearings:

The PTFE fabric replaces traditional coatings or liners in spherical plain bearings, significantly improving self-lubrication. The key manufacturing processes involve bonding and extrusion, where the fabric’s strength and elasticity play a vital role in ensuring no radial or axial clearance in the bearings. This enhances the manufacturing quality and performance of self-lubricating spherical plain bearings.

Prospects for PTFE Fiber Fabric:

The future development of PTFE fabric aims to enhance its load-bearing capacity, reduce the friction coefficient for higher swing speeds, and broaden its temperature range applicability. As the product range expands, it will elevate China’s self-lubricating spherical plain bearings to fully meet the demands of high-tech industries, contributing to the advancement of sectors like aviation and aerospace.

Plain Bearing Applications, Self-Lubricating Bearings, and Wear Parts

The applications for plain bearings are vast and varied, particularly when they are designed with self-lubricating features. A prime example of such a bearing is the high-temperature resistant type, which includes a metal backing. These bearings are adept at functioning in demanding conditions. Thrust washers also benefit from a metal backing, often reinforced with Kevlar for enhanced performance. This high-performance Kevlar bushing material is particularly useful in rotor vanes of compressors and vacuum pumps.

One noteworthy application of polytetrafluoroethylene (PTFE) fabrics is in plain bushings. These bushings are characterized by their controlled friction, exceptional abrasion resistance, and longevity. Woven PTFE layers are particularly effective in a myriad of applications, such as in bushes, bearings, thrust washers, and sliding pads. They demonstrate their value in diverse equipment like slaughtering machines, packaging machinery, escalators, and glass bottle cleaning apparatus, offering prolonged life and low wear rates which in turn reduce operating costs.

In wastewater processing equipment and lock gate bushes, woven PTFE layers are utilized due to their excellent wear resistance and dimensional stability. The woven PTFE layer, when combined with self-lubricating Kevlar bushings, creates a robust and versatile material. It offers high mechanical strength and wear resistance, with a low coefficient of friction. This makes it suitable for applications like hydraulic cylinder head bearings and crane bearings. It can function effectively in both dry conditions and when used with common lubricants.

In more demanding and heavily loaded applications, woven PTFE layer bearings backed with metal are a preferred choice. These are often used in oscillating and sliding bearings found in packaging equipment and forming machines, where their durability and performance are essential.

Low-Friction Teflon Bushings and Their Applications

Teflon fiber-based self-lubricating bearings are crafted from high-quality low-carbon steel, bronze, or stainless steel plates. These bearings incorporate Teflon fibers as both the base and the friction layer, firmly bonded together with a structural adhesive, creating a unified self-lubricating composite bearing material that is then shaped into a sliding bearing. To ensure the bonding strength between Teflon fiber and the metal plate. These Teflon filaments are interwoven with aramid filaments to further enhance the bond strength between Teflon fibers and metal plates.

These bearings are characterized by their high load capacity, excellent wear resistance, suitability across a broad temperature and medium range, simple and compact structure, and overall stability. PTFE, known for its self-lubricating properties, has one of the lowest coefficients of friction among solid materials. However, its wear resistance is typically limited due to low strength. This is often addressed by incorporating filled fibers or other fillers, albeit with limited effectiveness. Teflon fiber shells, with tensile strength 15 times higher than pure Teflon resin, significantly improve wear resistance while also preventing the cold flow phenomenon common with PTFE resin.

Teflon fiber-based self-lubricating bearings come in three varieties: steel-based, copper-based, and stainless steel-based.
