Exceptional Benefits:

  1. Outstanding Chemical Resistance:

    PTFE Rotary Shaft Seals are renowned for their exceptional resistance to a wide range of chemicals. This makes them ideal for use in harsh environments where exposure to aggressive chemicals is a concern, ensuring long-lasting performance and reliability.
  2. Broad Temperature Tolerance:

    With an operational temperature range of -40 to +220°C, PTFE seals are capable of performing reliably in extreme temperature conditions. This wide temperature tolerance makes them suitable for applications that involve both high and low-temperature environments.
  3. High-Speed Capability:

    Designed to handle peripheral speeds up to 30 m/s, PTFE Rotary Shaft Seals are perfect for high-speed applications. Their ability to maintain effective sealing at such speeds ensures the smooth operation of high-performance machinery.
  4. Pressure Stability:

    These seals can withstand pressures up to 15 bar, making them suitable for high-pressure applications. Their pressure stability is critical for maintaining a tight seal and ensuring the efficient operation of machinery.
  5. Versatility in Lubrication:

    PTFE Rotary Shaft Seals are effective in both insufficient lubrication and dry running conditions. This versatility allows them to adapt to various operational scenarios, reducing the risk of seal failure and enhancing overall machinery reliability.
  6. High Wear Resistance:

    The sealing lip of PTFE seals is engineered to offer high wear resistance, which is essential for applications involving continuous friction and movement. This wear resistance extends the service life of the seals, reducing maintenance needs and downtime.
  7. Low Friction:

    PTFE seals exhibit low friction and breakaway forces, which enhances the efficiency of the machinery. The reduction in friction not only improves performance but also minimizes energy consumption, contributing to overall cost savings.
  8. Customizable Designs:

    The flexibility in lip design allows for customized sealing solutions tailored to specific application requirements. This customization ensures that each PTFE Rotary Shaft Seal provides optimal performance for the machinery it serves.

The Illustrious History of PTFE

Spring Energized PTFE Seals

Today PTFE is one of the most widely used materials in the world. So, it may come as a surprise to learn that it was discovered entirely by accident!

How was PTFE discovered? In April of 1938, Dr. Roy Plunkett and his assistant Jack Rebok were working as chemists at DuPont’s Chemors Jackson Laboratory in New Jersey. On the night of the 6th, they stored the gas they were experimenting on (tetrafluoroethylene) in small cylinders where they were then frozen and compressed.

When the men returned the next day, they discovered that the gas they stored was gone. When they released the nozzle of the cylinders, no gas was released. Thinking this odd, they split the cylinders open to find the gas had turned into a solid, white, and waxy material.

This material would later become known as PTFE (polytetrafluoroethylene) or better known by its brand name Teflon.

The History of PTFE

Dr. Plunkett continued research on this strange new material and found that it was not only one of the slipperiest materials known, but that it also had several other incredible properties such as:

  • Non-Corrosive
  • Chemically Stable
  • Extremely High Melting Point

In 1941, Kinetic Chemicals Inc, a company founded by DuPont and General Motors, patented the new fluorinated plastic. In 1945 the name Teflon was trademarked. By 1948, Kinetic Chemicals was making over two million pounds of the Teflon brand PTFE.

PTFE-Coated Cookware

It wasn’t until 1954, when French-woman Collette Grégoire, wife of engineer Marc Grégoire, asked him to try the material he had been using on fishing tackle on her cooking pans. He subsequently created the first non-stick pans under the brand name Tefal (which is an amalgamation of “Tef” from “Teflon” and “al” from aluminum). The first PTFE-coated pan was introduced in the US in 1961 as “the Happy Pan”. Since then, non-stick cookware has been a staple in kitchens around the world.

Aside from cookware, PTFE has been used in a wide variety of applications, from food processing to the space industry. In fact, PTFE was used in the initial moon landing in 1969, as it was the only plastic that could withstand the extreme atmosphere of space.

Since then, PTFE has become a staple in our everyday lives and will continue to be so for many more years to come.

3 Key Factors For Spring-Energized PTFE Seals as First Choice in Oil & Gas Industry


Design and Selection of Appropriate Oil & Gas Seals:

As competition for natural resources increases, petrochemical companies have begun to look to new locations that pose new challenges – from arctic operations with low ambient temperatures to subsea equipment with high pressures and extreme temperatures.

PTFE Seals for Oil and Gas Industry

In addition, companies face higher demands for safety, reliability, and environmentally-friendly designs and processes.  There is also the challenge of reducing the footprint of structures and equipment for exploration and production of oil and gas.  All of these factors combined have driven up the costs involved in exploration and production, and made the design of oil and gas systems far more complex. 

The design and selection of appropriate seals is key to many of these issues… Read more
