The PTFE seal is a very attractive sealing material because of its low friction. Polytetrafluoroethylene is a polymer compound obtained by polymerizing tetrafluoroethylene. It has excellent chemical stability and corrosion resistance, and it is particularly noteworthy that it has little "dry" friction to steel. However, when used as a lip seal sealant, its main disadvantage is poor flexibility. When the shaft is vibrated and eccentric, the sealing performance is degraded.

This disadvantage can be overcome if it is a Teflon oil seal with a contact surface. At the same time, the contact surface can also be made into a forward acting oil seal with a back pumping effect to maintain a high sealing efficiency. The soft PTFE is refined. Durable and reliable sealing performance; PTFE itself has the best corrosion resistance and non-aging properties, has good creep resistance and cold flow resistance after special processing; can be safe for a long time in a wide temperature range Use; soft and easy to cut, can be cut by mechanical or manual, easy to install.

A high-sealing mat made of polytetrafluoroethylene without any binders or additives. It has strong chemical corrosion resistance; the special design makes the pad have strong creep cold flow resistance, which ensures the stable holding of the bolt fastening force during the sealing process; it has good flexibility, compression resilience and resistance. High and low temperature, non-aging, self-lubricating, etc.; soft and easy to cut, can be cut by mechanical or manual, easy to install; has a unique conforming molding ability, without special increase of pressing force, greatly extending the service life of the flange. It compensates for the irregularity of the sealing surface, and the sealing performance is reliable, especially the gas sealing property is very good.
