teflon (PTFE) has excellent chemical stability, can withstand all strong acids, strong bases, strong oxidants, and does not react with various organic solvents. PTFE can be used in a wide range of temperatures. It can be used for a long time at - 180 ℃~250 ℃ under normal pressure. After being treated at 250 ℃ for 1000h, its mechanical properties change little. PTFE has a very low friction coefficient, which is a good antifriction and self-lubricating material. Its static friction coefficient is less than the dynamic friction coefficient, so it has the advantages of small starting resistance and smooth operation when used to make bearings. PTFE is also an excellent electrical insulating material because of its non polarity, heat resistance and non water absorption. It also has excellent aging resistance, non viscosity and non flammability.

How should we choose PTFE gasket What about?

gather Tetrafluoroethylene gasket The quality is mainly reflected in the thickness tolerance. Polytetrafluoroethylene is not a good sealing material, with the exception of expanded tetrafluoroethylene. Ordinary tetrafluoroethylene gaskets, whether made of recycled materials or pure raw materials, have cold flow, that is, the thickness will change in a long time, and the compression screw should be tightened after a period of time, so the thickness tolerance is polytetrafluoroethylene Vinyl gasket As for the quality, there is also a gasket made of dispersed resin with complex processing technology. It is said that the quality is excellent, but the price will be very expensive.

As a sealing material, polytetrafluoroethylene has many applications. Because of its high corrosion resistance, stable physical performance, high and low temperature resistance, it has achieved good sealing performance and has been widely used in petroleum, chemical, pharmaceutical, juvenile and steel industries. Applicable media include water, oil, acid solution, alkali Solution and almost all chemical components. Durable and reliable sealing performance; Polytetrafluoro Z-ene has corrosion resistance and non aging properties, and has good creep resistance and cold flow resistance after special processing; It can be safely used for a long time in a wide temperature range; Soft and easy to cut, it can be cut mechanically or in red for easy installation.
