NEOPRENE All purpose. Resistant to vegetable oils. Generally not affected by moderate
chemicals, fats, greases and many oils and solvents. Generally attacked by strong oxidizing acids,
ketones, esters, nitro hydrocarbons and chlorinated aromatic hydrocarbons.
PTFE Chemically inert, virtually impervious. Very few chemicals are known to chemically react
with PTFE: molten alkali metals, turbulent liquid or gaseous fluorine and a few fluoro-chemicals
such as chlorine trifluoride or oxygen difluoride which readily liberate free fluorine at elevated
temperatures.

FKM
Shows good resistance to a wide range of oils and solvents; especially all aliphatic,
aromatic and halogenated hydrocarbons, acids, animal and vegetable oils. Hot water or hot
aqueous solutions (over 70ºF) will attack FKM.
For specific applications, always consult "Chemical Resistance Chart" Technical Bulletin.
