Material
|
AFM 39/2 is an asbestos-free gasket material. It consists of aramide fibers and other substances that are resistant to high temperatures and are processed with high-grade elastomers under elevated pressure and temperature.
|
|
Properties
|
The gasket material is physiologically safe and does not contain any colour
pigments.
On the one hand, this economical gasket material is conformable
and flexible, which ensures adequate sealing even with low surface pressure. On
the other hand, it provides adequately high stress resistance coupled with good
gas sealability.
In addition, AFM 39/2 is resistant to solvents, oils, fuels,
water, and many other media.
|
|
Application
|
- for sealed joints that are subject to moderate thermal and mechanical stress
- for lightweight components and flanges
- for apparatus, transmissions, pumps, sanitary fittings
- for sealing lightweight components with
comparatively low surface pressure, e.g. transmissions, valve covers, oil pans
and covers in IC engines.
Thanks to its physiological harmlessness AFM 39/2 can be used especially also in the drinking water and foodstuff sector.
|
|
Surfaces
|
As standard, both sides of AFM 39/2 are coated with a non-stick, high-friction layer that greatly facilitates disassembly.
In most cases, additional surface treatment is unnecessary.

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.
