Significance of PTFE And the Usefulness of Expanded PTFE

Introduction

PTFE – (  Polytetrafluoroethylene). It is otherwise called Teflon. PTFE was discovered on April 6, 1938, by an American scientist, Roy J. Plunkett. It was an accidental discovery that was later found to immensely impact our daily lives. This discovery is now being used in diverse sectors, from household kitchens to industrial sectors. These have become an essential part of our way of life.                      

       In this blog, we are going to know in detail why the PTFE tapes are important and also about the utility of expanded PTFE. To purchase ePTFE gasket sheets, visit our website at https://sealmax.in.

Why Is PTFE Important?

PTFE (Polytetrafluoroethylene) is a polymer built of organic compounds. It may not be the greatest discovery humankind has ever made, but it is a very significant one. For instance, there is an industry in which extremely crucial and expensive gas or liquid is stored. One of the intersections or connection points experiences a leak. Although the initial leakage will be small, it will grow significantly over time and cost the company thousands, if not millions to the company.

      Imagine another situation where you are the owner of an industry where harmful chemicals or gases are involved. Now imagine what will happen if a small portion of the harmful chemicals leaks and enters your body. The results will be devastating. Isn’t it?

        This is the reason why the discovery of PTFE is significant. PTFE is primarily used to stop gas and liquid leaks. Other utilizations include seals (including PTFE ‘O’ rings),  PTFE gaskets, chemical processing equipment, chemical transport, and PTFE components. In today’s time, PTFE is used as sealers,  non-stick agents, and for surface coating as well.

The Usefulness of Expanded PTFE

• The expanded PTFE is also called ePTFE. Since they have microporous structures, they are smooth and flexible.
• These have properties like chemical inertness, UV resistance, low dielectric constant, water tightness at low pressure, and excellent radial expansion, making them suitable for sealing and many other industrial applications.
• The expanded PTFE is suitable for medical devices, high-performance filters, and electronic insulators because of its permeability.
• These are carefully applied to the chemical pipe flanges in the oil and gas industries to achieve a proper seal.
• In many applications, Expanded PTFE is used in the form of a cord, sealing tape, or gasket.

Conclusion

Even if PTFE isn’t the greatest invention ever, it will undoubtedly revolutionize how liquids and gases are handled.

Key Takeaways

• PTFE – Polytetrafluoroethylene. It is otherwise called Teflon.
• PTFE is primarily used to stop the leakage of gas and liquids and also as a sealer, insulator, non-stick agent, and surface coating.
• Other utilizations include seals (including PTFE ‘O’ rings), PTFE gaskets, valves, , surface coatings, chemical processing equipment, chemical transport, PTFE components
• The expanded PTFE is also called ePTFE. These are microporous and hence permeable, smooth, and flexible and do not have cold flow.

The expanded PTFE is suitable for medical devices, high-performance filters, chemical equipment’s, flanges , heat exchangers etc.
