Key features of Ultrason^®

BASF’s Ultrason^® grades are amorphous, high-performance polymers with outstanding temperature and chemical resistance as well as constant high purity.

Processing advantages

Thermoplastic processing: suitable for small and large injection-molding and extrusion applications
Good melt stability: allowing for stable processing
Lowest cyclic dimer content: stable membrane spinning solutions
Constant high product quality: enabling stable membrane casting

Metal replacement: tailored Ultrason^® grades for different electrolyzer technologies and applications

BASF offers a tailored Ultrason^® portfolio for the individual performance requirements of today’s and next-generation AWE, PEM and AEM electrolyzers to enable large-scale production of green hydrogen.

BASF is a global partner but acts locally when it comes to developing high-quality injection-molded parts and high-performance separator membranes. BASF supports all interested companies with choosing the right Ultrason^® grade and offers experience during part and tool design, up to final serial manufacturing.

Lead the transformation to clean energy – with BASF’s specialty plastic Ultrason^®, just like the electrolyzer manufacturer Stargate Hydrogen!

Stargate Hydrogen is now using Ultrason^® to manufacture the frames in its stacks used for alkaline water electrolyzers (AWE). The polysulfone (PSU) Ultrason^® S replaces metals such as nickel, resulting in significantly lighter stacks. This substitution is possible because BASF’s high-performance thermoplastic offers high temperature and chemical resistance also in harsh alkaline conditions. It can withstand high stack pressures due to excellent compression strength. As Ultrason^® can be injection-molded, it provides greater design flexibility for easier functional integration than metal.
