Ethylene
propylene rubber is an elastomer prepared from ethylene and propylene
monomers (ethylene propylene copolymer) and at times with a small
amount of a third monomer (ethylene propylene terpolymers). Although
EP is a relatively new introduction to the rubber industry (1961),
it has won broad acceptance in the sealing world because of its
excellent resistance to Skydrol and other phosphate ester type
hydraulic fluids. Ethylene propylene has a temperature range of
-65 to +300 degrees F (-54 to +149 degrees C) for most applications.
EP
is recommended for:
- Phosphate
ester base hydraulic fluids (Skydrol, Fyrquel, Pydraul)
- Steam
(to 400 degrees F) (204 degrees C)
- Water
- Silicone
oils and greases
- Dilute
acids Dilute alkalles
- Ketones
(MEK, acetone)
- Alcohols
- Automotive
brake fluids
EP
is not recommended for:
- Petroleum
oils
- Di-ester
base lubricants
