Application of PTFE gasket :

1. The surface of the non bonded flange is easy to repair and replace, and can maintain excellent sealing performance under harsh cyclic conditions such as high temperature, low temperature, high vacuum, and impact vibration.

2. Suitable for sealing parts with intense temperature and pressure fluctuations, it is a static sealing component at flange connections such as pipelines, valves, pumps, heat exchangers, towers, manholes, and hand holes. By changing the tension of the wrapped steel strip, the density (hardness) of the wrapped gasket can be changed to meet the needs of various application parts. It is widely used in industries such as petrochemical, machinery, power, metallurgy, shipbuilding, medicine, atomic energy, and aerospace.

The above introduction is about the usage and application of PTFE gaskets, which do not add any adhesive or deform during processing. They have good flexibility, are easy to install, and have a unique design style.

The commonly used production method for PTFE gaskets is to press (cut) the PTFE sheet into shape on a punch, or to cut the PTFE rod into shape on a lathe.

1. Polytetrafluoroethylene is a type of fluoroplastic. With carbon atoms as the skeleton, fluorine atoms are symmetrically and evenly distributed around it, forming a tight barrier, making it highly valuable for its comprehensive performance.

2. Polytetrafluoroethylene has high corrosion resistance to strong acids, alkalis, and oxidizing agents, and will not act even at high temperatures. Its corrosion resistance even exceeds that of glass, ceramics, stainless steel, and even gold and platinum, so it is known as the "king of plastics". In addition to some aromatic compounds that can cause slight swelling of polytetrafluoroethylene, it has corrosion resistance to organic solvents such as ketones and alcohols. Only molten alkali metals and elements such as fluorine can act on it at high temperatures.

3. PTFE has excellent dielectric properties, outstanding insulation strength and arc resistance, low dielectric loss tangent, but poor corona resistance. PTFE does not absorb water, is not affected by oxygen or ultraviolet radiation, and has good weather resistance. After 3 years of outdoor exposure, the tensile strength remained almost unchanged, with only a decrease in elongation. Polytetrafluoroethylene film and coating can penetrate water and gas due to their fine pores.

4. Gaskets are materials placed between two planes to strengthen sealing. To prevent fluid leakage, sealing components are set between static sealing surfaces. There are dozens of processing and forming methods for PTFE. The commonly used method is to press (cut) polytetrafluoroethylene sheets into shape on a punch, or to cut polytetrafluoroethylene rods into shape on a lathe.
