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
