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.
