Ultrason® Hydrogen

Scale up your green hydrogen production with Ultrason^®!

If you want to be the frontrunner in the green hydrogen economy, then Ultrason^® is the material of choice for you! The Ultrason^® portfolio (PAES: polyarylethersulfones PSU, PESU, PPSU), offers a tailored material range which is ideally suited for various components in alkaline water (AWE), proton exchange membrane (PEM) and anionic electrolyte membrane (AEM) electrolyzers.

Your benefits with Ultrason^®

Exceptional chemical and high-temperature resistance
Design freedom due to thermoplastic processing
Lower weight electrolyzers via metal replacement
Stable membrane casting due to high and stable material quality
Well-founded processing knowledge for efficient part design process

Save time, costs and become a frontrunner in the electrolyzer market

• We support you from choosing the right Ultrason^® grade via part and tool development to the final production of the parts. We can replace nickel, ni-plated steel, PEEK, PPS, PEI and PEN.

• We are your global partner for developing high-quality plastic parts and high-performance membranes locally – with more than 30 years of know-how in plastic processing (also for large parts), material performance and membrane production.
