Material
|
AFM 20 consists of a tanged and galvanized steel core. An
asbestos-free soft material compound
containing aramide fibers, inorganic fillers and high-grade binder elastomers is applied to both sides of the core.
|
|
Properties
|
AFM 20 exhibits good creep resistance, and conforms well to
sealing faces.
|
|
Application
|
For cylinder head gaskets in medium-range IC engines and other
sealed joints subjected to mechanical and thermal stress, e.g. intake and exhaust
manifolds, transmission flanges, and high-pressure pumps.
|
|
Surfaces
|
For special applications, full-surface or partial coatings are available, e.g. a non-stick coating on a PTFE basis (also
possible on materials in roll form) or a silicone-based coating that
improves micro-sealing (only available as a finished gasket). Screen printing
with various elastomers is also possible.

The data quoted above are valid for the material "as delivered" without
any additional treatment. In view of the countless possible
installation and operating conditions, definitive conclusions cannot be
drawn for all applications regarding the behaviour in a sealed joint.
Therefore, we do not give any warranty for technical data, as they do
not represent assured characteristics. If you have any doubt, please
contact us and specify the exact operating conditions.
