Introducing Udel® PSU HYRA
Driving progress toward a hydrogen-powered future with advanced materials for structural components.
At Syensqo, we’re leading the transition to efficient and more scalable hydrogen technology systems across the value chain.
HYRA, which stands for Hydrogen Related Applications, is a family of polymer materials specifically designed to meet the challenging requirements of green hydrogen-related applications. With this product range, we can open new doors for metal-to-plastic conversion and simplified design, enabling function integration, increased assembly efficiency and cost optimization.
HYRA embodies progress, performance and innovation, unlocking new possibilities for the future of hydrogen technologies.
