EPDM rubber (ethylene propylene diene monomer rubber) [1] [2] [3] is a type of synthetic rubber that is used in many applications. EPDM is an M-Class rubber under ASTM standard D-1418; the M class comprises elastomers with a saturated polyethylene chain (the M deriving from the more correct term polymethylene).
It is used to create a watertight covering to protect the interior of a building. Membrane roofs are most commonly made from synthetic rubber, thermoplastic (PVC or similar material), or modified bitumen. Membrane roofs are most commonly used in commercial application, though they are becoming increasingly common in residential application. [1] [2]
The term, a portmanteau of elastic polymer, [2] is often used interchangeably with rubber, although the latter is preferred when referring to vulcanisates. [3] Each of the monomers which link to form the polymer is usually a compound of several elements among carbon , hydrogen , oxygen and silicon .
Examples include Viton rubber, EPDM and butyl rubber. A new class of synthetic rubber is the thermoplastic elastomers which can be moulded easily unlike conventional natural rubber vulcanized rubber. Their structure is stabilized by cross-linking by crystallites in the case of polyurethanes or by amorphous domains in the case of SBS block ...
Ethylene propylene rubber (EPR, sometimes called EPM referring to an ASTM standard) is a type of synthetic elastomer that is closely related to EPDM rubber. Since introduction in the 1960s, annual production has increased to 870,000 metric tons .

EPDM is primarily used for applications where it will be exposed to water, outdoor conditions, or glycols. For anything mineral oil related, NBR is the better choice. I think where it says EPDM is used for oil cooler hoses, they mean hoses carrying coolant, not oil, but that's super confusing, and I think it should be removed.
It manufactures EPDM rubbers, TPVs and KEPA. It was founded in 1985 and is currently the 3rd largest producer of EPDM in the world (220,000 tonnes per year. [1]) The company currently supplies its products for various uses including automobiles, hoses, seals and wire insulation. [2]
