EP, En or EPDM ethylene-propylene (EPDM) compounds are prepared from ethylene and propylene and usually a third monomer. These compounds are used frequently to seal phosphate ester fire resistant hydraulic fluids such as skydrol. They are also very effective in brake systems, and for sealing hot water and steam. Ethylene-propylene compounds have good resistance to mild acids, alkalis, silicone oils and greases, ketones, and alcohols.
