    Material
    AFM 80 is an asbestos-free gasket material. It contains aramide fibers, inorganic fillers and other high-temperature resistant substances which are bonded with high-quality elastomers with high strength and especially gas-tight under increased pressure and increased temperature.
    Properties
    AFM 80 inimitably unites key aspects of gasket technology in a single material: adaptability, gas-tightness and strength.
    It boasts excellent mechanical/thermal resistance yet is soft and adaptable at the same time. It is ideally suited for sealing gases and fluids.
    AFM 80 achieves exceptional sealing results and adapts to the component surfaces even at low surface pressures – even under heavy loads from pressure, vibration or narrow sealing webs.
    Application
    • for refrigerating compressors, apparatus, transmissions, air compressors, housings
    • for flanged joints, pumps, fittings
    • for applications requiring a gasket material showing excellent mechanical strength as well as adaptability
    • for sealing refrigerant fluids and oils, transmission/ hydraulic/ engine oils. fuels etc.
    • for sealing gases, e.g., carbon dioxide, nitrogen, natural gas, hydrogen etc.
    Surfaces
    As standard, both sides of AFM 30 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.
