We all know that in the chemical industry, the biggest problem is corrosion. Especially in some chemical plants transported by pipelines, the pipelines need to be connected. The products transported by pipelines face a lot of corrosion, whether internal or external. Can guarantee the long-term use of the pipeline.

Especially at the joints of pipelines, the joints are easily corroded. If the joints are not in place or used for a long time, these will cause cracks or leaks at the joints. We know that the chemical industry encounters many chemicals They are both strong acids and alkalis. If there is leakage at the connection, it will inevitably cause great safety hazards and cause casualties. This must be paid attention to.

What kind of product can ensure the safety of the connection? Make the connection tighter and ensure the normal operation of the pipeline. The most important thing is the gasket. At present, PTFE gasket is used. The raw material of this gasket is polytetrafluoroethylene. This material product has acid resistance. Alkali resistance, high temperature resistance, 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.

We need to understand that polytetrafluoroethylene is a polymer compound formed by the polymerization of tetrafluoroethylene. It has excellent chemical stability and corrosion resistance. It is one of the best corrosion resistance materials in the world today. In addition to fluorine, it is resistant to all other chemicals and does not change when boiled in aqua regia. It is widely used in various working conditions that require resistance to acids and alkalis and organic solvents, tightness, high lubricity and non-stickiness, electrical insulation and good anti-aging. Performance, temperature span can be long-term work at the temperature of +250 ℃ to -180 ℃.

Its birth has solved many problems in the fields of chemical, petroleum, pharmaceutical and other fields in the world. It has been widely used as a sealing material and a filling material.

Now it has a very important impact in all walks of life.
