Expect good resistance to dilute acids and alkalis, ozone, UV and weathering, and ketones. EPDM (EPR) offers good electrical insulating characteristics, strong performance in outdoor and exposed installations. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Exposure to aromatic hydrocarbons or petroleum oils and fuels will shorten service life.
It sees regular use in water and steam systems, potable water applications, and brake and phosphate ester systems.
