PTFE energized seals have found a multitude of applications in the aerospace industry. There are many reasons for the use of PTFE in aerospace. It offers excellent strength, extremely low friction, toughness, dimensional stability, and abr…
Automotive PTFE Shaft Seals In this article, we are going to explore the reasons why PTFE seals are among the best choices for many automotive applications. You’ll find PTFE seals in fuel cell seals, fuel injection pumps, steering wheel se…
PTFE rotary shaft seals are an excellent solution to high speed applications with surface speeds up to 30 m/s. In this article, we are going to look at four reasons behind that continued popularity. Reason # 1 Low Friction PTFE, also known…
The impressive growth of the medical device, biomedical and healthcare industries over the past 15 years continues unabated even as materials such as fluoropolymers are meeting the increasingly challenging demand for new products and proce…
There are a few things about Teflon to start with that by no means tell the full picture, but are certainly the list of things that caused me to immediately abandon ship on all things teflon. Teflon is the trademarked name for the chemical…
1938: Fiddling around in the lab one day, Roy Plunkett accidentally discovers polytetrafluoroethylene, soon to be known as Teflon, a slippery substance that will have practical applications in everything from nonstick cookware to a preside…
1. Aircraft Industries PTFE tubings are the non-flammable fluoropolymers that have lower friction coefficient which make them able to work properly under extreme temperature and pressure that's why these tubings are being used in the aircr…
What are Teflon and PFOA? Where are they found? Teflon® is a brand name for a man-made chemical known as polytetrafluoroethylene (PTFE). It has been in commercial use since the 1940s. It has a wide variety of uses because it is extremely s…
One of the primary uses of bellows is to absorb dimensional changes due to thermal effects, which is very useful when used high temperature flows such as steam. Bellows also serve to dampen vibration in the system caused by rotating compon…
Ball Valve Seals Material Choice The choice of a seal material for a ball valve is vital to its successful operation. In this post, we are going to look at some of the major characteristics of six commonly used options for polymer seals in…
Evolution of Seal Materials The evolution of seal materials evolved as seals faced more rugged demands. Early needs could be met using packed hemp or leather, but as the demands became more and more rigorous new materials were sought. This…
For decades, DuPont has sold the answer to crud, gunk, and grime. What the company didn’t advertise was that its nonstick wonder sticks—to us. Congresswoman Pat Schroeder was scrambling eggs, one day back in 1984, when she coined one of th…
PTFE APPLICATIONS PTFE’s significant chemical, temperature, moisture, and electrical resistances make it an ideal material whenever products, tools, and components need to be durable and reliable in even the most strenuous applications. On…
Polymer Bellows and Diaphragms PTFE (polytetrafluoroethylene), aka Teflon, is typically the first choice polymer for bellows and diaphragms, but did you know that PTFE isn’t the only polymer you can choose from? In this article we are goin…
PEEK, which stands for polyetheretherketone, is a well-known engineering thermoplastic. It has become a popular choice for bushings that must operate in demanding high-speed, high-temperature environments. In this post, we will look at 6 r…
The PTFE Rotary Seal Difference PTFE rotary seals are often the answer when elastomeric seals just can’t handle the demands. In this article we are going to look at just five ways that PTFE seals differ in performance and behavior from ela…
The medical device industry faces continually evolving challenges when it comes to finding the right sealing solutions for new and improved designs. Issues such as sterilization, wide ranges of expected pressure, potentially aggressive env…
For a number of years fluoropolymers have played a significant role in the chemical and similar industries to protect plants and equipment against chemical attack by a broad range of aggressive media. This is because they offer substantial…
PTFE Rotary Shaft Seals Outperform Rubber Shaft Seals Elastomeric seals performed well for many years, but as the applications and environments became more demanding, elastomers had a hard time keeping up. If the application pressure is ab…
Home cooks who enjoy conveniently sliding eggs out of a pan know all about Teflon’s non-stick properties. But Teflon’s applications go well beyond cookware, and growth in several industries is driving global demand for the material. Teflon…
Most people have never heard of PTFE industrial coating, but when you mention Teflon, a look of understanding passes easily on their faces. PTFE (Polytetrafluoro Ethylene) is the technical name of the material, and it’s commonly sold under…
Polytetrafluoroethylene or PTFE (more commonly known as Teflon) is a particularly versatile ivory-white and opaque plastic fluoropolymer; it is made by the free-radical polymerisation of many tetrafluoroethene molecules, and is suitable fo…
Since its discovery nearly 80 years ago, polytetrafluoroethylene (PTFE), has become one of the world’s most versatile and useful materials. Originally used for military applications, it can now be found in many other applications, such as …
The range of available materials is one of the key hurdles to adoption for industrial 3D printing. 3D printing is being rapidly adopted by product manufacturers all around the world, but it still can't compete with many other manufacturing…
