Material
|
AFM 32/2 is an asbestos-free gasket material. It consists of
aramide fibers and other asbestos substitutes that are resistant to high
temperatures and are processed with high-grade elastomers under
elevated pressure and temperature.
|
|
Properties
|
AFM 32/2 exhibits excellent thermal/mechanical resistance as well
as high tensile strength. It is also conformable and is particularly suitable
for sealing oils and other fluid substances.
|
|
Application
|
- for sealed joints in IC engines that are subject to high
mechanical stress (e.g. intake manifolds, oil pans)
- for sealing transmissions, compressors, pipelines and apparatus
- for sealing engine, transmission, hydraulic, and refrigerating oils
- for sealing fuels, mixtures of water and antifreeze & corrosion inhibitors
- for sealing Freons, alkaline solutions, and solvents
|
|
Surfaces
|
As standard, both sides of AFM 32/2 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.
