In 1975, Asahi Kasei began the first commercial chlor-alkali production using the membrane electrolysis process. Asahi Kasei has continued to lead the world in pioneering the development of membrane electrolysis technology, including the Aciplex^TM F perfluorosulfonic acid membrane. The membrane process for chlor-alkali electrolysis eliminates the need for mercury and asbestos as process materials, and enables greater energy efficiency. The superiority of Asahi Kasei chlor-alkali process technology has been recognized throughout the world, and the Aciplex^TM F membrane is employed in plants with a total production capacity of over 17 million tons of caustic soda per year.
