As a material, EPDM (EPR) delivers good electrical insulating characteristics and very good flexibility at low temperature. This material stands up to dilute acids and alkalis, brake fluid, and phosphate ester hydraulic fluids. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). It should not be specified for service in aromatic hydrocarbons or mineral oil-based lubricants.
Typical settings include outdoor equipment, brake and phosphate ester systems, and HVAC and refrigeration.
