Germany, Sept. 11 -- The electrolyzer manufacturer Stargate Hydrogen, Estonia, is now using BASF's Ultrason(R) to manufacture the frames in its stacks used for alkaline water electrolyzers (AWE). The polysulfone (PSU) Ultrason(R) 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(R) can be injection-molded, it provides greater design flexibility for easier functional integration than metal. The collaboration between Stargate Hydrogen and BASF has yielded an exceptional re...
