Friction coefficient µG
The friction coefficient between gasket and flange surface was determined for different types of gasket materials in an ESA research project.
The gasket Flachdichtung PTFE Dichtung, Profil FD30, WS 7110 DB, Dichtungsdicke 2 mm, Rev. 00 can be assigned to the categorie 2 : "Gaskets based on filled PTFE". Therefore, the following friction coefficients can be considered:
| Temperature / °C | Friction coefficient |
|---|---|
| 20 °C | 0.23 |
