In applications such as on-tank valves in hydrogen-powered vehicles, Vespel® SCP-5000 ensures reliable performance even after millions of cycles, without showing signs of hydrogen embrittlement or rapid gas decompression.  The excellent ductility of Vespel® 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, ensuring the safe handling of hydrogen, including in liquefied forms. Vespel® SCP-5000 is set to play a vital role in advancing hydrogen technologies, offering unparalleled performance in the most demanding environments.
