Verified reliability statements

{Doc->DisplayTitle}

Temperatures, aggressive media, cleaning processes, flavoring materials – seals for the processing industry are subjected to a wide range of stressful influences. Reliable, meaningful statements on stability as issued by Freudenberg Process Seals are therefore an essential criterion for selecting the correct solution.

There is no elastomer that is universally applicable. Bearing this in mind, our materials are thoroughly tested for every application with regards to their media stability and also the upper and lower temperature limit, to be able to provide you with meaningful recommendations for the optimal material selection.
