In the past, the selection of seals seemed relatively simple, mainly including mechanical shaft seals, oil seals, O-rings and rubber seals. However, with the innovation of industrialization and automation, we have seen the rise of a new sealing solution which uses polytetrafluoroethylene (PTFE, commonly known as Teflon) as an important sealing component. Through various energizer such as, springs, O-rings or silicone, PTFE seals are able to offer a reliable sealing performance in various application. Teflon seals (PTFE seals) provide low friction sealing solution even with high operating pressures and/or high surface speed conditions.

5 outstanding characteristics of Teflon seals:

The chemical name of Teflon material is (Polytetrafluoroethylene abbreviated as PTFE), many people refer it as "the King of Plastics". PTFE seals have excellent characteristics that make it the first choice in a variety of applications. Here are some reasons why PTFE seals outperforms traditional rubber seals:

•     • High chemical resistance: PTFE seals perform well even in high corrosive environment. It is resistant to aggressive media and is suitable for fluids with a pH range from 0 to 14.
•     • High Pressure Resistance: PTFE seal elements can withstand high pressure environments and maintain their sealing properties which makes them suitable for applications requiring high pressure sealing.
•     • High temperature resistance: Teflon seals can work under extreme temperature conditions ranging from -260°C to +300°C.
•     • Low Coefficient of Friction: PTFE sealing material has a very low coefficient of friction, which reduces friction and improve sealing efficiency and sealing life.
•     • Wear Resistance: The wear resistance of PTFE allows the seal to have outstanding performance in reciprocating applications which helps to reduce maintenance costs.

Application

Teflon sealing materials are used in a wide variety of industries and applications:

•     • Industrial Applications: These seals play critical roles in industrial equipment including high pressure, extreme temperature, and corrosive environments and more.
•     • Food and pharmaceutical industry: PTFE seals are widely used in food and pharmaceutical production due to its high chemical stability and non-toxicity characteristics.
•     • Semiconductor Manufacturing: Seals with PTFE component ensures a reliable sealing performance under extremely clean environment making them a critical role in semiconductor sector.
•     • Oil field and energy industry: Teflon seals provide effective sealing solution for high pressure and high temperature environments for oil field and energy industry.
•     • Construction and Automotive Manufacturing: PTFE seals play a key role in construction machinery and automotive equipment because of their ability to withstand harsh conditions.
