PTFE (Polytetrafluoroethyene) is a fluorocarbon polymers. The chemical structure of PTFE has the hydrogen atoms of polyethylene completely displaced by fluorine atoms to form a high molecule. This is a very stable structure. That is why PTFE is a polymer that never age.
PTFE is a superior sealing material. It is clean and non-sticking, you can use it for food industry. It can work up to 260 C. It can work at PH 0-14. it can be processed into film, block or any shape. It has a low coefficient of friction and lubrication is not always necessary. PTFE can work together with other materials like fiberglass or copper to get a better mechanical property. When PTFE is expanded properly, the fiber changes from hair-like structure to a web-like structure and become much more stronger while it is much lighter.
PTFE is also a young material. Until today SinoSeal and its team has been probing into this new product and you can definitely expect progress in this field.
[ Features ]
Compound O-Ring adopts special rubber resisting high temprature,F+ plastic and special engineering to compound this sealing product.It not only has low contraction permanent set functions of rubber O-ring,but also resist heat,cold,oil,friction,chemical corrusion and other performances.It can be used in all kind of dynamical seal and static seal widely,meanwhile can replace all traditional rubber and plastic o-ring.
[ Main properties ]
We can produce other no-nominal compound o-ring.
[ Specifications ]
Compound o-rings combines the good futures of rubber and PTFE. Rubber is a elastomer but it might be unable to resist strong acid or alkalis. The PTFE jacket outside help to protect the rubber since PTFE can work at PH 0-14. It is often used under some harsh circumstances.
