PTFE Seals Do not adhere to any substance

Poly PTFE gasket has a very good lubrication effect, in the solid material friction system minimum. What is the outstanding advantages of poly-PTFE gasket in the end it also can meet the different needs of users. Here by Shuo Feng machinery for you to do a detailed introduction.

Polytetrafluoroethylene gasket weather resistance, polytetrafluoroethylene in the plastic in the best aging life. PTFE gasket itself has a high resistance to erosion, physical function is not chaos, high and low temperature resistance, the achievements of its good sealing function, in the petroleum, chemical, pharmaceutical, power, steel industry has a wide range of applications.

Polytetrafluoroethylene gaskets are not adherent, polytetrafluoroethylene has the smallest surface tension in solid materials and does not adhere to any substance.

Polytetrafluoroethylene gasket low temperature, with good mechanical toughness; even if the temperature dropped to -196 ℃, can also maintain a 5% elongation. Commonly used in the temperature, pressure alternating intense sealing parts, is the pipeline, valves, pumps, heat exchangers, towers, manholes, hand holes and other flange connection of the static sealing components.

Polytetrafluoroethylene gasket itself has a high resistance to erosion, physical function is not chaos, high and low temperature resistance, the achievements of its good sealing function. It can be used to meet the needs of various applications. It is widely used in petrochemical, mechanical, power, metallurgy, shipbuilding, medicine, atomic and aerospace industries by changing the tightening force of the surrounding strip. The

Polytetrafluoroethylene gaskets are resistant to erosion and are inert to most chemicals and solvents, are resistant to strong acid and alkali, water and various organic solvents. This gasket compression rebound function is good, with multi-channel seal and a certain self-tightening function, the department can eliminate the pressure, temperature changes and mechanical vibration.

The above is about how the polytetrafluoroethylene gasket is to meet the needs of the market, which is due to poly PTFE gasket has a unique technical design features, and continuously meet the needs of users, also won the majority of users love. Chemical production plants in a certain temperature and pressure conditions, the process requires strict, the raw materials involved in a variety of gases, liquids, solids, physical differences vary, the need for various types of production equipment. But these devices in contact with the media in the production of corrosion at all times, thus seriously restricting the development of chemical and other industries. In the case of underdeveloped technology, people are always looking for corrosion resistance in the metal. But these devices are often high weight, can not solve a lot of corrosion problems. After that, people began to explore with non-metallic resources to replace the metal. Plastic is the first application in our country is polytetrafluoroethylene, followed by polytetrafluoroethylene, polytrifluoroethylene, polyfluoroethylene propylene and other fluorine plastic and polyethylene, polypropylene, ABS and other thermoplastic plastics one after another.
