## 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 UNIFLUOR® PTFE with glass microspheres filler, FD01, WS 7550, thickness 3 mm, Rev. 02 can be assigned to the categorie 2 : "Gaskets based on filled PTFE". Therefore, the following friction coefficients can be considered:
