EPDM

EPDM is a terpolymer of ethylene and propylene with a small amount of a third monomer (usually a diene) to allow curing with sulfur.

EPDM O-rings are useful for numerous industries, from automotive assembly to water purification systems.

​

In general, they are known to have excellent resistance to ozone,  heat, water and steam, alkalis, slightly acidic and oxygenated solvents, ozone and sunlight (UV) and have excellent flexibility at low temperatures, good resistance chemistry (many dilute acids and alkalis as well as polar solvents) and good electrical insulating properties.

EPDM O-rings are generally black in color, with long-lasting preservation.
