Trelleborg Sealing Solutions showcases new sealing solutions and capabilities for the entire hydrogen value chain at Hyvolution 2025, from January 28 to 30 at Paris Porte de Versailles, hall 4, booth 4S50.
Trelleborg highlights its expanding H2Pro™ range of 20-plus materials proven for applications in the production, transport and storage, and end-use of hydrogen, and demonstrates its FlexiBond solution, designed for use in electrolyzers and fuel cells.
Daniel Hauser, Manager Lead Group Hydrogen, says: “Our comprehensive range of more than 20 H2Pro™ materials, proven in our proprietary testing regimes to meet the requirements of real-world hydrogen applications, are now available for customers across the hydrogen value chain.
“We will also showcase one of our latest innovations in the H2Pro™ portfolio, FlexiBond. It enables new design possibilities for electrolyzers and fuel cells by combining the capabilities of large frame seals with a high stability shape, and reduces the level of investment needed for complex injection molding equipment.”
H2Pro™ materials provide optimal sealing solutions in challenging hydrogen environments including high pressures and low temperatures, and are characterized by minimal hydrogen permeation, resistance to rapid gas decompression (RGD) and excellent abrasion and extrusion properties.
At Hyvolution Trelleborg also highlights its industry-leading R&D capabilities, recently enhanced by a new 93 sq meter/1,000 sq feet hydrogen test facility in Fort Wayne, Indiana, US. The development is part of Trelleborg’s strategic goal to be a leader in hydrogen sealing and testing to help customers navigate the challenges of the entire hydrogen value chain
The extended testing capabilities offered in Fort Wayne include hydrogen leak detection, compatibility, dynamic testing and permeation testing, which are all critical criteria for sealing hydrogen. Engineering experts perform tests that replicate worst-case application conditions for rapid gas decompression, where hydrogen in a high-pressure system can be absorbed into a seal and if the pressure is suddenly relieved, gas trapped in the seal can expand, potentially causing the seal to blister and crack as the gas tries to escape. There are also testing capabilities for pressures up to 1,500 bar/15,000 psi and across all temperature ranges from cryogenic to above 180 °C/350 °F, and environmental thermal cycle testing at various pressure profiles.
Trelleborg, together with Ensinger Plastics, also showcases an innovative portfolio of combined solutions from the worlds of rubber and plastics. These include components made from high-performance plastics designed for the challenging requirements of sealing gaseous hydrogen (CGH2) as well as liquid hydrogen (LH2) at cryogenic temperatures. Also presented are multi-component parts used in valves or as cell frames and bipolar plates in electrolyzers and fuel cell stacks.
