What Is a Compression Gasket?

The English abbreviation is PTFE (commonly known as "Plastic King") and the trade name is Teflon® . This material product has the characteristics of acid and alkali resistance, high temperature resistance, and resistance to various organic solvents. It is widely used in the chemical and pharmaceutical industry and can be called the originator of the gasket industry.

Teflon gasket

The English abbreviation is PTFE (commonly known as "Plastic King") and the trade name is Teflon® . This material product has acid resistance

High temperature resistance-use working temperature up to 250 ° C.

Low temperature resistance-with good mechanical toughness; even if the temperature drops to -196 , it can maintain 5% elongation.

Corrosion resistance-For most chemicals and solvents, it is inert, resistant to strong acids and alkalis, aqua regia and various organic solvents.

Weather resistance-has the best aging life among plastics.

High lubrication-the lowest coefficient of friction in solid materials.

Non-stick-the smallest of solid materials

There are many applications of PTFE as a sealing material. Because of its high corrosion resistance, stable physical properties, and high and low temperature resistance, it has achieved its good sealing performance and has been widely used in the petroleum, chemical, pharmaceutical, power, and steel industries. Suitable media include water, oil, acid solution, alkali solution and almost all chemical components.

The application of PTFE in sealing materials is not only sealing gaskets, but also packing and soft packing. These products can be found on the website and will not be described one by one here.
