What is PTFE gasket?

PTFE gasket, also known as PTFE gasket or Teflon gasket. It is made of PTFE rods, tubes, plates by mechanical turning or cutting into flat gaskets, V-shaped gaskets, piston rings, ball valve gaskets, etc.

This article will introduce PTFE gaskets from two aspects: performance and application

Performance of PTFE gasket

Corrosion resistance

PTFE gaskets have extremely strong corrosion resistance. Only a few elements such as molten alkali metals and elemental fluorine under high temperature and high pressure can affect it. This makes it particularly good when dealing with corrosive media.

Anti-aging

PTFE gaskets are not affected by oxygen and ultraviolet rays, and have good weather resistance. After 3 years of outdoor exposure, the tensile strength remains almost unchanged, and only the elongation decreases.

Insulation

PTFE gaskets have good insulation properties and are suitable for applications that require electrical insulation.

High lubricity

It has a lower friction coefficient among solid materials, which helps to reduce friction losse

Cleanliness 

As a clean sealing product, PTFE gasket will not contaminate any substance it contacts, and is particularly suitable for sealing parts such as food and medicine where contamination is not allowed.

Application range of PTFE gaskets

PTFE gaskets are widely used in many fields due to their excellent performance, mainly including

Chemical industry

 Due to its excellent corrosion resistance, PTFE gaskets are widely used in the chemical industry for sealing various pipes, valves and containers.

Petroleum industry

 In the process of oil extraction and refining, PTFE gaskets are used to seal equipment containing corrosive media .

Pharmaceutical industry

 The cleanliness and corrosion resistance of PTFE gaskets make it an important sealing material in the pharmaceutical industry

Food industry

In the process of food processing and packaging, PTFE gaskets are used to ensure the hygiene and safety of sealing parts

Electronic and electrical industry

 With its excellent insulation performance, PTFE gaskets have important applications in electronic and electrical equipment

Aerospace

 In extreme environments, PTFE gaskets are used to seal key components to ensure the reliable operation of the system

In summary, PTFE gaskets have become an indispensable and important sealing material in modern industry with their unique performance and wide range of applications
