CAUTION! Operating temperature limitations are as follows:
Materials
Buna 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 hyrdrocarbons.
EPDM Shows very good water and chemical resistance. Has poor resistance to oil and solvents,
but is fair in ketones and alcohols.
Neoprene All purpose. Resistant to vegetable oil. 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.
Santoprene
Injection molded thermoplastic elastomer with no fabric layer. Long mechanical flex
®
life. Excellent abrasion resistance.
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.
Viton
®
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 70°F) will attack Viton
