Expanded PTFE Rope is made of 100% PTFE of puffed PTFE material cut or punched. Expanded PTFE material (eptfe) expands PTFE into a unique material with strong, tough and porous properties and is highly fibrotic.

It not only maintains the unique properties of PTFE itself – excellent chemical stability (not affected by general chemicals); extremely low coefficient of friction; wider operating temperature; non-aging and permanent durability;

Now its multi-fiber structure gives it an unimaginable tenacity as a sealing product, and more importantly, it fundamentally solves the common problems of other types of tetrafluorine sealing materials — creep and cold flow, which greatly improves the performance compared with pure tetrafluorine gaskets and filled tetrafluorine gaskets. In addition, it is easy to cut, easy to install, and has a long service life. This is undoubtedly a remarkable revolution.

1)100% teflon. It has all the properties of teflon, resistant to all corrosive media.
2) Pressure: <20 MPa.
Temperature: -260℃~+260℃
3) Excellent anti-wriggle variation ability and cold current resistence. Even in case of cross change of temperature and pressure, good sealing can be assured
4) Soft, twistable and bendable at will Even gravely rusted and worn out sealing, superface, as long as it is used, the equipments may continue their service and keep its best performance
5) Easily to be used and replaced Just cut a certain length of the sealing ribbon then put it on the surface of the target, any formed & sized sealing ring can be obtained only its two ends are connected
6) Great interchangeability Only have several kinds of ribbons with general specifications, numerous equipments can be used .It’s easy to store and purchase.
