FKM is not generally resistant to ketones, low molecular weight esters (such as ethyl acetate), or nitro containing compounds. products are not usually serviceable below - 15 degrees F.

Low-temperature resistance is normally not favorable and for static applications is limited to approximately –15°F (–26°C) although in certain situations it is suitable down to –40°F (–40°C). Under dynamic conditions, the lowest service temperature is between 5°F and 0°F (–15°C and –18°C). Gas permeability is very low and similar to that of butyl rubber. Special fluorocarbon compounds exhibit improved resistance to acids, fuels, water, and steam.
