The compound resists brake fluid, water and steam, and dilute acids and alkalis. EPDM (EPR) is specified for excellent hot water and steam resistance, very good flexibility at low temperature. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Verify compatibility before use with mineral oil-based lubricants or petroleum oils and fuels.
You will find this material specified across solar and roofing assemblies, brake and phosphate ester systems, and HVAC and refrigeration.
