Greene Tweed introduces PFAS-free sealing material built for hydrogen and CCUS reliability
Greene Tweed has announced the launch of EPM 893, a PFAS-free ethylene propylene compound engineered to improve sealing reliability in critical hydrogen and carbon capture, utilisation, and storage (CCUS) service.
The latest addition to Greene Tweed's energy transition solutions portfolio, EPM 893 supports a wide range of applications, including hydrogen refuelling systems, valves, instrumentation, mechanical seals, underground storage, CO2 compressors, pumps, and pipeline infrastructure.
As hydrogen and CCUS systems scale, seals must withstand high-pressure gas exposure, rapid pressure cycling, aggressive process media, and low-temperature operation conditions that cause conventional elastomers to crack, blister, lose elasticity, or degrade. In addition, teams are rethinking materials they have long relied on in light of certain per- and polyfluoroalkyl substances (PFAS) regulations. EPM 893 helps address these challenges through low-temperature sealing performance, rapid gas decompression (RGD) resistance, and compatibility with hydrogen, supercritical CO2, oxygen, and amine-based carbon capture processes, while eliminating PFAS.
"Companies building hydrogen and CCUS infrastructure need partners who can grow with them from production and capture through transport and storage," said Charles Burke, General Manager, Sealing Systems and Seal-Connect. "EPM 893 expands a portfolio Greene Tweed is building for that full value chain, and signals where we will continue to invest and deliver end-to-end design expertise for the total sealing system as these markets mature."
