As a material, EPDM (EPR) offers good electrical insulating characteristics, strong performance in outdoor and exposed installations. Expect good resistance to water and steam, ozone, UV and weathering, and ketones. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Exposure to aromatic hydrocarbons or mineral oil-based lubricants will shorten service life.
