Trelleborg’s H2Pro™, our new hydrogen sealing material range offers solutions across the hydrogen value chain, from production to storage and transport to end use.
Hydrogen plays a critical role in the transition to sustainable energy, both as a fuel source and as a storage medium for surplus energy from renewable sources. Due to its inherent characteristics, it is difficult to seal but the expanding H2Pro™ range offers reliable solutions for the wide array of applications, including pumps, valves, connectors, and numerous other devices in the hydrogen supply chain.
Two new hydrogen-specific sealing materials:
• H2Pro™ EBT25, a new EPDM for high-pressure environments across a wide range of temperatures
• Zurcon® H2Pro™ ZLT, a unique thermoplastic polyurethane (TPU) for very low temperatures
Supporting the energy, power generation, off-highway, truck and bus, CPI, chemical transportation, and marine industries, all H2Pro™ materials are validated to key industry standards in a range of challenging conditions typical of hydrogen environments.
