Material
AFM 30 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 30 is conformable and exhibits excellent mechanical/thermal resistance, as shown by its high value of residual stress. It is ideal for sealing gases and fluids.

Application
  • for compressors, pipelines, apparatus, transmissions, gas meters and IC engines
  • for sealing engine, transmission, hydraulic, and refrigerating oils
  • for sealing fuels, mixtures of water, antifreeze & corrosion inhibitors
  • for sealing Freons, alkaline solutions, and solvents

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.
