Fluoro rubber – FKM
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 ageing. 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
non-polar solvents
ozone, weathering, ageing, UV resistance

FKM is not resistant to:
glycol-based brake fl uids
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
