FKM materials have conquered many applications in
which high thermal and / or chemical resistance is
required. FKM also has excellent resistance to ozone,
weathering and aging. very low gas permeability,
FKM is recommended for vacuum applications.
FKM has good resistance to:
mineral oil-based oils and greases
aliphatic hydrocarbons
aromatic hydrocarbons
chlorinated hydrocarbons
hydraulic fluids HFD
vegetable and animal oils and fats
silicone oils and silicone greases
fuels
nonpolar solvents
ozone, weathering, aging, UV resistance
FKM is not resistant to:
glycol-based brake fluids
polar solvents (e.g., acetone)
superheated steam (special grades)
hot water (special grades)
amines, alkalis (special grades)
low-molecular organic acids (e.g., acetic acid)
application temperature range:
-15 to +200°C (short term +220°C)
down to -61°C and up to 260° C is realistic with special
grades
