Elastomer Technology

Ethylene-propylene EPM/EPDM - General grades

Ethylene-propylene (EPM/EPDM)
These compounds have excellent resistance to weathering, ozone, hot and cold water and steam.

Chemical properties
They display resistance to aliphatic phosphate-ester hydraulic fluids, acids, alkalis, salt solutions, alcohols, glycols and silicone oils.

Typical operating temperatures
-45°C to +120°C continuous, or +150°C intermittent. EPM grades are available for use with hot water service up to +180°C.   

Fluid sealing duties
Often used with steam raising plant. They must not be used with mineral oils or di-ester based lubricants.

Our EP62 range is WRAS approved for potable water applications.

James Walker standard grades
Supplied in hardnesses 50-90 IRHD.
