Properties
FKM's are serviceable in continuous heat of up to 250º C and intermittent heat of up to 300º C.
Satisfactory resistance to low temperatures of typically -20º C and - 40º C by use of special grades.
FKM's exhibit good flame resistance and are usually self extinguishing upon removal of flame source.
All FKM's have excellent resistance to oxygen, ozone and natural weathering..
FKM compounds have outstandig resistance to compression, especially at elevated temperatures.
Resistance to chemicals; amongst all synthetic rubbers FKM's are the most resistant to many of the solvents and chemicals, giving long service where other materials do not. Excellent resistance against hydrocarbons, aliphatics, aromatic and chlorinated chemicals. Good resistance to acids and alkali's including oxidants. They do have poor performance against ethers, ketones, and bases.
