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 Elastikdichtung mit Diffusionssperre - Unifluor® Einlage, Profil ED10, WS 7110/7550, Dichtungsdicke 4 mm, Rev. 01 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 |
