Carbon Capture Technology Expo Europe
DuPont Highlights Vespel® SCP-5000 polyimide polymer for Hydrogen Valve Applications at the 2024 Hydrogen Technology Expo Europe
)
The nature of hydrogen requires specialized materials that resist hydrogen embrittlement, exhibit low permeability, and maintain integrity under extreme conditions. With excellent material properties, Vespel® SCP-5000 offers outstanding resistance to hydrogen, retaining its mechanical properties under high pressures and cryogenic temperatures. This material's low hydrogen permeability is a critical factor in preventing leaks, significantly outperforming other engineering thermoplastic materials.
DuPont will showcase Vespel® SCP-5000, a high-performance polyimide polymer suited for hydrogen valve seats at stand 3C5 at the Hydrogen Technology Expo at Hamburg Messe, Germany. As hydrogen continues to gain traction as an alternative fuel source, the demand for materials that can withstand the unique challenges of hydrogen exposure increases.

This material's low hydrogen permeability is a critical factor in preventing leaks, significantly outperforming other engineering thermoplastic materials.
In applications such as on-tank valves in hydrogen-powered vehicles, Vespel® SCP-5000 provides reliable performance even after millions of cycles, without showing signs of hydrogen embrittlement or rapid gas decompression. The excellent ductility of Vespel® polyimide at cryogenic temperatures (-253°C) further enhances its suitability for hydrogen applications, where other polymers may become brittle. The mechanical properties of Vespel® SCP-5000—described as “soft, but strong”—make it a well-suited choice for critical sealing applications. This material provides excellent creep resistance across a broad range of temperatures and loads, for safe handling of hydrogen, including in liquefied forms. Vespel® SCP-5000 is set to play a vital role in advancing hydrogen technologies, offering remarkable performance in the most demanding environments.
