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 UNIFLUOR® PTFE mit Füllstoff Bariumsulfat, Profil FD01, WS 7553, Dichtungsdicke 2 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
