Precision Polymer develops steam resistant EPDM elastomer

28-Jan-14

Precision Polymer Engineering has developed EnDura E90SR, a new EPDM elastomer material that provides outstanding high temperature steam resistance. EnDura E90SR is available as o-rings, t-seals and custom-molded geometries and is used in equipment such as pumps, valves, turbines, geothermal tools and drilling equipment. Unlike traditional EPDM materials EnDura E90SR can withstand high temperatures (up to 550°F) and high pressures, with excellent resistance to rapid gas decompression. These properties make the new material ideal for use in anaerobic high-temperature environments, such as those encountered in geothermal applications and enhanced oil recovery applications. E90SR is the latest addition to PPE’s EnDura range of high performance elastomers specifically developed for high pressure environments. The EnDura range now includes all major polymer chemistries including fluoroelastomers (FKM), hydrogenated nitrile (HNBR), tetrafluoroethylene/propylene dipolymers (FEPM) and perfluoroelastomer (FFKM). “EnDura E90SR is a significant advancement within the EnDura product line because the elastomer material exhibits resistance to high temperature steam far superior to standard EPDM materials, with the additional benefit of being resistant to rapid gas decompression,” said Steve Jagels, PPE global market manager, oil and gas. “EnDura E90SR is designed to last longer than standard materials in high temperature steam, preventing critical equipment downtime and costly repairs.” EnDura E90SR is now available in all o-ring sizes and seal geometries.
