Material
AFM 32/2 is an asbestos-free gasket material. It is composed of aramide fibres and other asbestos substitutes which are resistant to high temperatures. These substitutes are processed with high-grade elastomers under elevated pressure and temperature.
Properties
AFM 32/2 exhibits high mechanical and thermal stability as well as high tensile strength. It is also conformable and is particularly suitable for sealing off oils and other fluid substances.
Application
- for sealing joints in internal combustion engines which are subject to high mechanical stress (e.g. intake manifolds,oil pans)
- for transmissions, compressors, pipelines and apparatus
- for sealing off transmission, hydraulic, refrigerating and motor oils
- for sealing off fuels, mixtures of water and antifreeze and corrosion inhibitors
- for sealing off Freons, alkaline solutions and solvents
Surfaces
The standard version of AFM 32/2 has a non-stick top and bottom layer with a high coefficient of friction. This facilitates dismantling. Additional surface treatment is unnecessary in most cases.
