Polytetrafluoroethylene (PTFE) is a polymer compound made by the polymerization of tetrafluoroethylene. It is widely used in petroleum, chemical, pharmaceutical, electric power, and iron and steel industries. Applicable media include water, oil, acid solution, alkali solution, and almost all chemical components.
High sealable pad made of expanded PTFE without any binder or additive. Strong chemical corrosion resistance;
The special design makes the plate have strong creep resistance to cold flow, so as to ensure the stability of the bolt fastening force in the sealing process;
It has good flexibility, compression resilience, high and low-temperature resistance, no aging, self-lubrication, etc. Soft and easy to cut, can be cut mechanically or manually, easy to install; With unique adaptability forming ability, without a special increase of compression force, greatly extend the service life of flange. Make up for the irregular sealing surface, reliable sealing performance, and especially excellent gas sealing performance.
Using inorganic material as filler, it is evenly dissolved into PTFE raw material after deep processing.
Compared with pure PTFE, modified PTFE has the advantages of higher compressive strength, wear resistance, good thermal conductivity, and reduced thermal expansion. The multidirectional fiber structure makes the product highly resistant to chemical corrosion, free of cold flow and creep, and has reliable sealing for a long time.
The pad filler is inorganic, does not contain any binder, will not produce adhesion with the sealing surface, and repeated use on the same sealing surface. Easy to cut, can be cut mechanically or by hand, and easy to install. There is no aging problem, can be stored for a long time.
