As a material, EPDM (EPR) delivers strong performance in outdoor and exposed installations, very good flexibility at low temperature. It resists phosphate ester hydraulic fluids, water and steam, and brake fluid. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). It should not be specified for service in mineral oil-based lubricants or aromatic hydrocarbons.

You will find this material specified across solar and roofing assemblies, outdoor equipment, and HVAC and refrigeration.
