Reasons to Use Teflon as a Gasket

Teflon is a tradename of Polytetrafluoroethylene, which is the most-used artificial substances in the world. PTFE is popular due to its versatility and outstanding chemical properties. It offers a wide array of applications in various industries.

In laboratories, Teflon has been used in piping, tubes, vessels because of its chemical inertness and resistance. No contaminants stick to the surface of the Teflon material. The Teflon material is most popularly used in pharmaceutical, food and beverage, and cosmetics industries because of its pure nature, as no microbes can grow in it. Also, because the Teflon material can withstand high temperatures of baking and drying ovens. PTFE or Teflon is an ideal material of choice for the gaskets because of its unlimited advantages. The Teflon gaskets are of three types Virgin, Filled, and Expanded. Further fillers are also added in it to enhance its properties.

The following are the reasons why Teflon is perfect as a sealing material.

Low Friction

The Teflon is renowned for its slippery nature. The pans and some other kitchen appliances are usually made of the Teflon material as well to get the non-stick properties. The extremely slippery property of the Teflon makes it ideal for the gaskets which utilize rotary or reciprocating motion.

Hydrophobia

As the PTFE is totally resistant to water and other liquids, the seals created from the Teflon are also resistant to liquids. The Teflon seals are perfect for those liquids that need to be contained.

Chemical Resistance

The PTFE remains stable in an environment that involves strong liquids and bases. There are only some chemicals that can actually strike the Teflon as they are chemically inert.

Heat Tolerance

The Teflon gaskets are extremely heat-tolerant, which makes them adequate for a wide range of applications. The actual reason is its melting point which is 327℃ to 620°F.

Electrical Conductivity:

Teflon proves itself as an excellent insulator with extremely low conductivity characteristics. It is used to insulate wires and in gasket work where currents need to be contained.

Long-Lasting:

The Teflon gaskets suppliers provide such Teflon sealings that are incredibly durable and can withstand all weather conditions. These Teflon gaskets are unaffected by ultraviolet and are resistant to discoloration or oxidation.
