Buna-n -
General purpose, oil resistant. Shows good solvent, oil, water and hydraulic fluid resistance. Should not
be used with highly polar solvents like acetone and MEK, ozone, chlorinated hydrocarbons and nitro hydrocarbons.

Neoprene -
All purpose. Resistant to vegetable oil. Generally not affected by moderate chemicals, fats greases
and many oils and solvents. Generally attacked by strong oxidising acids, ketones, esters, nitro hydro carbons and
chlorinated aromatic hydrocarbons.

Virgin PTFE -
Chemically inert, virtually impervious. Very few chemicals are known to react chemically 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.

halogenated hydrocarbons, acids, animal and vegetable oils. Hot water or aqueous solutions(over 70
