Description: A copolymer of ethylene and propylene (EPM), sometimes combined with a third comonomer (EPDM), Ethylene Propylene has gained wide seal industry acceptance for its excel lent ozone and chemical resistance characteristics.

Temperature Range: Standard Compound: 60 ^oF to +300 ^oF. (Dry Heat Only)

Hardness (Shore A): 40 to 90.

Features: With a working temperature range of 60^oF to +300^oF, depending upon the com pound, EPM/EPDM excels in its resistance to the very same chemical agents that cause rapid and extreme deterioration in Nitriles.

In particular, EPM/EPDM features good resistance to such polar solvents as ketones (MEK and Acetone). It is also highly recommended for effective resistance to steam (to 400^oF); hot water; silicone oils and greases; dilute acids and alkalies; alcohols and automotive brake fluids.

EPM/EPDM further features excellent resistance to aging by both ozone and sunlight.

EPM/EPDM can also be compounded for FDA approved applications.

Limitations: With the exception of resistance to polar solvents, EPM/EPDM is not recommended for its overall solvent resistance.

And, unlike Nitriles, this elastomer performs poorly when exposed to petroleum oils, diesterbased lubricants (MILL7808), or aromatic fuels.
