Fluorocarbon has excellent resistance to
high tem¬peratures, ozone, oxygen, mineral oil, synthetic
hydraulic fluids, fuels, aromatics and many organic solvents
and chemicals. Low temperature resistance is normally not
favorable and for static applications is limited to approxi¬mately
-26°C (-15°F) although in certain situations it is
suitable down to -40°C (-40°F). Under dynamic conditions,
the lowest service temperature is between -15°C and -18°C
(5°F and 0°F).
• Gas permeability is very low and similar
to that of butyl rubber. Special FKM compounds exhibit an
improved resistance to acids, fuels, water and steam.
Heat resistance
• up to 204°C (400°F) and higher temperatures
with shorter life expectancy.
Cold flexibility
• Down to -26°C (-15°F) (some to -40°C)
(-40°F).
Chemical resistance
• Mineral oil and grease, low swelling in ASTM oil No.
1, and IRM 902 and IRM 903 oils.
• Non-flammable hydraulic fuels in the group HFD.
• Silicone oil and grease.
• Mineral and vegetable oil and grease.
• Aliphatic hydrocarbons (fuel, butane, propane, natural
gas).
• Aromatic hydrocarbons (benzene, toluene).
• Chlorinated hydrocarbons (trichlorethylene and car¬bon
tetrachloride).
• Fuels, also fuels with methanol content.
• High vacuum.
• Very good ozone, weather and aging resistance.
Not compatible with:
• Glycol based brake fluids.
• Ammonia gas, amines, alkalis.
• Superheated steam.
