Hydroelectric power was the reason why the company’s site in the Isar Valley south of Munich was chosen in 1911. A number of clean hydroelectric power stations had been built along the Isar, and Dr. Gustav Adolph and Albert Pietzsch, the founders of the company, used the River Isar as a source of electric power and cooling water for the electrochemical production of hydrogen peroxide.

Today United Initiators is a global and leading producer of peroxide-based initiators and specialty chemicals and offers a broad range of organic peroxides, persulfates and selected specialty chemicals. The company has several production facilities in Europe, North America and the Asia‐Pacific region.
