Expanded PTFE Cords
The Expanded PTFE cord has high residual thickness at time of installation and highest recovery properties. The round expanded PTFE has very good adaptability to shafts and flange surfaces and very low sliding friction.
The PTFE cord is avery clean material, harmless in contact with food. It's often used as sealing for valve spindle, for shaft seals, tube flanges, as PTFE cord sealing for tanks, in the apparatus engineering, machine housings, food processing systems, pharmaceutical systems.
The Expanded PTFE cord is compliant to FDA, EC1935/2004 and is fully suitbale for applications with food contact.
Advantages:
- 100 % expanded PTFE (ePTFE) without fillers
- universal velve packing
- high mechanical properties
- high chemical resistance
- reduced cold flow and improved recovery
- non-toxic, biologically inert
- non-flammable
Expanded PTFE Valve packing cord
The expanded PTFE cord packing is a round gasket cord consisting made from expanded PTFE with a modified structure. The patented processing method strengthens the fibre structure of the string seal and improves remarkably its mechanical properties. Thanks to the special processing method the cord seal features a higher compactness, a lower cold-flow tendency and better recovery properties. The expanded PTFE cord packingis a universal valve string designe..
What are the primary advantages of using Expanded PTFE Cords in industrial applications?
Expanded PTFE (Polytetrafluoroethylene) cords offer several benefits, including excellent chemical resistance, high-temperature stability, and low friction properties. These cords are non-toxic, making them ideal for use in food processing and pharmaceutical applications. Additionally, the expanded structure of PTFE allows for greater flexibility and adaptability, ensuring a tight seal in various environments.
How does the performance of Expanded PTFE Cords compare to traditional sealing materials?
Compared to traditional sealing materials, Expanded PTFE Cords provide superior sealing capabilities due to their compressibility and ability to conform to surface irregularities. This results in a more reliable seal that reduces leakage and extends the lifespan of the sealing solution. Furthermore, Expanded PTFE is less prone to wear and tear, maintaining its integrity under extreme conditions.
Can Expanded PTFE Cords be used in high-pressure applications?
Yes, Expanded PTFE Valve packing cord is well-suited for high-pressure applications. Its unique properties enable it to withstand significant pressure without deforming or losing its sealing capability. This makes it an excellent choice for valves, pumps, and other critical components in high-pressure systems.
