FKM seals display very good resistance to media, ozone and aging. The material is also stable in fuels as well as petroleum-based oils and greases, along with aliphatic and aromatic hydrocarbons. It is unstable with regard to polar solvents (e.g. acetone, MEK and ethyl acetate), low molecular weight organic acids (formic and acetic acid), glycol-based brake fluid, ammonia gas, amines, alkalis and superheated steam.Information provided by Freudenberg Sealing Technologies. |
