Introducing EPM 893: A New Material for Low-Temp, High-Pressure Hydrogen & CCUS Applications

As the hydrogen economy scales, the elastomeric seals inside Hydrogen storage tanks, refueling stations, and green hydrogen production process are being pushed past their limits, as well as CO2 capture, compression, transportation, and storage. Engineers face a brutal combination that no single material has reliably handled: rapid gas decompression (RGD) that blisters and cracks seals when pressure drops, low operating temperatures, and exposure to 100% hydrogen at pressures up to 70 MPa (10,150 psi), and supercritical CO2 up to 150°C and 20 MPa. Tightening PFAS regulations add a further constraint, forcing teams to rethink materials they have long relied on.

Join Greene Tweed for the launch of EPM 893, a new low-temperature, RGD-resistant EPM compound engineered to eliminate that trade-off. Validated through extensive testing with external labs and customers, EPM 893 delivers proven RGD resistance and reliable sealing at temperatures as low as -55°C, withstands hydrogen, CO2, amines, and KOH, and achieves complete elimination of PFAS.

In this webinar, we will unpack the technical pain points facing hydrogen sealing applications, walk through the ISO 17268 / SAE J2600 tests in Hydrogen and modified ISO 23936-2 RGD results in both Hydrogen and supercritical CO2 behind the compound’s performance, and show where it fits across the hydrogen and CCUS value chains. Discover how one compound can close the gap between safety, durability, and sustainability.
