EPDM
Ethylene propylene diene monomer rubber
EPDM is a ethylene and propylene based rubber. It boasts good wear resistance and outstanding resistance to alkaline cleaning agents, organic solvents, alcohols and superheated water.
As it is resistant to glycol brake fluid, EPDM is the main sealing material used in vehicle brake systems.
