A high temperature, steam resistant, EPDM elastomer material designed for geothermal applications including pumps, valves, turbines, drilling tools and equipment. In addition to geothermal applications EnDura® E90SR may be used in steam applications for enhanced oil recovery and general purpose high temperature hot water and steam applications.

EnDura® E90SR offers a maximum temperature rating in anaerobic steam up to 288°C (550°F), and may be used in short durations up to 315°C (600°F) in steam. This performance greatly exceeds standard EPDM materials.

EPDM provides broad chemical resistance to polar fluids, however E90SR is not recommended for hydrocarbon based oils and fuels. The material has been tested for explosive decompression resistance in carbon dioxide to NACE TM0297-97.
