Compared to other nonmetallic materials, it is relatively expensive — this is partly because it has some of the most beneficial properties of any nonmetallic material and is as such in high demand. Faster turnaround. Compression stamping equipment can achieve up to 400 strokes/minute, enabling the production of hundreds of thousands of washers each day. For over nine decades, New Process Fibre has provided customers with high-quality and innovative non-metallic solutions, including Teflon washers. Our Teflon washers find application in a wide range of industries—including automotive, HVAC, and plumbing—providing durable and reliable performance even when exposed to water, oil, chemicals, and high heat. At New Process Fibre, we maintain over 10,000 dies ranging from .080–10 inches in our in-house manufacturing facility. Combined with our custom tooling capabilities, this quality allows us to produce Teflon washers in virtually any size to meet a customer’s needs.
Thermal insulating washers are made out of a material called PTFE. PTFE is a polytetrafluoroethylene (PTFE)-based synthetic fluoropolymer of tetrafluoroethylene, a high-molecular-weight compound consisting of carbon and fluorine — and is one of the most commonly used artificial substances in the world.PTFE can be divided into two main styles. Virgin PTFE, which is fairly hard, like plastic, however it will still compress to make a seal between two faces. Expanded PTFE is more like a sponge, making it ideal for sealing damaged, glass or plastic flanges because it compresses more easily than the Virgin grade. Manufacturers employ a few different methods to produce Teflon washers. Two of the most common manufacturing methods are compression molding and machining. HVAC systems employed in industrial, commercial, and residential facilities experience significant amounts of vibrations due to moving systems parts and air currents. These vibrations can result in premature wear and fatigue in individual components, especially fasteners located at connection points. Using durable washers, such as those made of Teflon, can help mitigate the vibrations produced to protect critical joints. Plumbing PTFE washers are naturally highly chemical resistant and self-lubricating, which allows for accurate torquing and smoother operation. Teflon washers find application in virtually every industry, including in the following: Automotive
The compression molding process employs a compression mold and press to stamp washers from Teflon material. Compared to other manufacturing processes, such as injection molding, compression molding offers several advantages, including: Advanced Seals and Gaskets Ltd uses years of experience and globally sourced materials to produce our vast catalogue of Seals and Gaskets along with associated foam and rubber products. Our Cellular Sponge Rubber range is vast and varied with differences in density, grade, quality etc which can all be tailored towards a particular application. Its chemical resistance enables washers made from it to remain stable even when exposed to compounds such as road salts and pollution. After all, a washer is a piece of precision engineering. Therefore, having the right measurements can be the difference between a perfect seal and a leaky joint. Can you cut PTFE Washers to length? In contrast to our competitors who use reprocessed material for their washers, at New Process Fibre we use the highest quality virgin Teflon resin available on the market to manufacture our Teflon washers.Our PTFE washers come in a variety of shapes, from simple round or square designs to custom designs with several holes and or slots across the flange. Greater precision and accuracy. The process is suitable for producing identical parts in high volumes from batch to batch.
Teflon™ PTFE products are commonly found in a number of different applications and are particularly popular because of their unique set of properties, which includes resistance to both water and oil, and an extremely low coefficient of friction. Moreover, the material’s heat and chemical resistance coupled with its fairly high strength makes it both durable and dependable. Being chemically inert, except for some alkaline metals, means PTFE Gaskets are the seals of choice in food, pharmaceutical and chemical sectors. PTFE washers and PTFE gaskets can be supplied not only in its virgin state, but also with carbon and/or glass inserted into it leaving the finished product more durable and able to withstand even higher temperatures. Ask a member of our sales team for more information. Data sheets can be supplied free of charge upon request. Tightening nuts into place on bolts and other fasteners. Washers evenly distribute the pressure of a fastening point across a larger surface area to reduce strain and the risk of damage. RH Nuttall Limited produce washers, gaskets, seals, strip and sheet PTFE for a variety of applications. General CharacteristicsFurthermore, it can handle up to 500 volts per mil and temperatures up to 600 degrees F while maintaining dimensional stability, resistance against creep, and the anti-frictional properties for which the product is so well known. This means that with these products, one can expect consistent, long lasting performance. Compared to metal, nylon and Teflon offer greater application versatility and durability when used in the manufacture of washers. While both are synthetic polymer materials with excellent mechanical strength and frictional resistance, they vary in regard to best use cases due to the differences in their manufacture and, consequently, their physical and chemical characteristics. For example: As our longtime customers know, there are so many reasons to choose Superior Washer & Gasket Corp. as your source for any washer and shim you could need. We not only have the ability to rapidly manufacture washers that meet the diverse needs of OEMs, fastener distributors, and professionals in all types of industries, we do so in a way that puts customer service and satisfaction first. Our daily practices are built around fulfilling your needs, answering your questions, and ensuring the products you rely on perform to the highest expectations. We can even create washers and shims on-demand, so any custom requirements you have can be met, and promptly. To get the best in product quality and integrity, trust us to provide it and show you why we’re the leading choice for washer manufacturing and supply. Our Capabilities And Services
Industry professionals in the plumbing industry generally turn to non-metallic washers for their operations due to the near-constant exposure of equipment and systems to water and other fluids. Non-metallic washers offer greater resistance to water-related issues such as corrosion. Additionally, Teflon’s near-complete resistance to water and oil and temperatures up to 600° F allow it to retain its form and integrity even when exposed to excessive moisture and high heat. A washer is a small circular component that is specifically designed to improve the seal, alignment or space between two other parts inside a device. When there are gaps or loose fitting components inside machinery, there is a risk of movement that can then lead to friction damage. If movement continues to occur between poorly fitted parts, the inside of the machinery could suffer from long-term damage that could jeopardise its safety and performance. By fitting a washer in place of any gaps, you create a tighter fitting alignment, therefore preventing unnecessary movement. For a number of years, metal served as the default material for washers. However, the introduction of durable and reliable plastics, such as Teflon, has led to the acceptance of plastics as a suitable alternative.Teflon is hydrophobic, meaning it resists mixing with water. Compared to nylon, it has a higher melting and better chemical resistance. These qualities make it suitable for equipment systems regularly exposed to moisture or requiring significant amounts of lubrication.
