Showa Denko K. K. (昭和電工株式会社 Shōwa Denkō Kabushiki-gaisha?) is a leading Japanese chemical engineering firm.
Formed in 1939 by the merger of Nihon Electrical Industries and Showa Fertilizers, Showa Denko K.K. (SDK) manufactures chemical products and industrial materials. SDK's products serve a wide array of fields ranging from heavy industry to the electronic and computer industries. The company is divided in five business sectors: petrochemicals (olefins, organic chemicals, plastic products), aluminum (aluminum cans, sheets, ingots, foils), electronics (semiconductors, ceramic materials, hard disks), chemicals (industrial gases, ammonia, agrochemicals), and inorganic materials (ceramics, graphite electrodes). Showa Denko has more than 180 subsidiaries and affiliates including Showa Denko America in New York, NY, USA. The company has vast overseas operations and a joint venture with Netherlands-based Montell and Nippon Petrochemicals to make and market polypropylenes. In March 2001, SDK merged with Showa Denko Aluminum Corporation to strengthen the high-value-added fabricated aluminum products operations, and is today developing next-generation optical communications-use wafers.
Showa Denko is a member of the Mizuho keiretsu.
Prior to World War II it was a part of the Mori group of companies as Showa Fertilizer (昭和肥料 Shōwa Hiryō?). It was founded by Nobuteru Mori in the early 1930s, and opened the first ammonium sulfate factory in Japan in April 1931.
