Introducing Radel® PPSU 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.

Radel® PPSU HYRA grades
- Radel® HYRA R-9100 NT15: Radel® HYRA R-9100 NT15 is an opaque, general purpose polyphenylsulfone (PPSU) grade designed for injection molding. It offers exceptional hydrolytic stability and toughness superior to other commercially-available, high-temperature engineering resins. This resin also offers a high deflection temperature and outstanding resistance to environmental stress cracking. Radel® polymers are inherently flame retardant, provide excellent thermal stability and possess good electrical properties. This grade is suitable for the processing of large parts using injection molding or compression molding.
- Radel® HYRA R-9100 BK937: The black version of the Radel® HYRA R-9100 NT15. This polyphenylsulfone (PPSU) grade, designed for injection molding, is black in color and is specifically formulated for hydrogen applications and use in a harsh operating environment. This grade is suitable for the processing of large parts using injection molding or compression molding. The color package is designed for laser-welding techniques.
