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 designed to seal spindles in highly aggressive or very clean environments, in particular for demanding applications in the food and pharmaceutical industry. The gasket cord seals particularly well slowly rotating and oscillating shafts. The gasket is also suitable for many static applications, in which the use of an adhesive is undesirable.
Advantages
  • high residual thickness at time of installation
  • higest recovery properties
  • very good adaptability to shafts and flange surfaces
  • very low sliding friction
  • very clean material, harmless in contact with food
