Showa Denko has more than 180 subsidiaries and affiliates. The company has 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.

Petrochemicals Sector
The Petrochemicals Sector supports the growth of Showa Denko's basic business through the manufacture and sales of organic chemicals, olefins and specialty polymers.
SDK is the leader of the Asian ethyl acetate market.The Oita Plant, the main manufacturing base, supplies SDK and other chemical companies with the basic materials for making acetyl derivatives, synthetic resin, synthetic rubber, and styrene monomers.
Innovative products include a new heat-resistant, transparent sheet and film that can be used in flexible displays such as electronic paper and organic EL displays.
Chemicals Sector
Originally focused on general-purpose industrial gases, medical gases, and industrial chemicals, SDK now provides a variety of products including high-purity gases and chemicals for the semiconductor industry. As the semiconductor industry shifted to other asian locations, SDK established overseas specialty gases production sites in Shanghai and Singapore.
The company also offers an array of technologies and products covering various fields, including food additives, feed additives, cosmetic ingredients, medical and agricultural intermediates, optical-function materials, information-recording materials, functional polymeric materials, differentiated composite material, and liquid chromatography equipment (Shodex).
SDK recently launched an environmental initiative to reduce waste and encourage chemical recycling.
Electronics Sector
The Electronics Sector includes compound semiconductors, rare earth magnetic alloys, solid aluminum capacitors, and hard disks.
The compound semiconductors business deals with the crystal growth process, providing a wide range of products including Ultrabright LED Chips as well as blue LED Chips.
The solid aluminum capacitor business relies on conductive polymers, a combination of inorganic aluminum materials with organic polymers. The products offer with high heat resistance and high capacitance.
The electronics sector also produces aluminum-based and glass-based hard disks as well as aluminum substrates for hard disks. In september 2008 SDK annouced a consolidation their hard disk (HD) media operations by establishing a joint venture with Hoya corporation in January 2009. The joint venture, will owned about 75% by SDK and about 25% by HOYA.
Inorganics Sector
The Inorganics Sector consists of the Ceramics Division, Carbons Division and Fine Carbon Department.
SDK's Ceramics products are used in a wide range of fields, including chemical products, refractory products, ceramics, paper manufacture, plastics and electronics.
Key products include alumina hydroxide, alumina, and high-purity alumina. SDK also produces fused alumina abrasive grains, silicon carbide and boron nitride.
SDK produces artificial graphite electrodes, an indispensable material for the recycling of steel. Other products include fine carbulizing agents for iron casting.
In addition to VGCFTM carbon nanofibers and fuel battery materials already on the market, SDK is focusing R&D efforts on high-functionality carbon products, including battery materials, electronics materials, and materials for alternative energy solutions.
Aluminium Sector
SDK produces heat exchangers, beverage cans, and other high value-added fabricated products from aluminum materials (including rolled, extruded and forged products).
Controversy
Niigata Minamata disease
The company is known for causing the second outbreak of Minamata disease (a type of severe mercury poisoning) in Kanose, currently part of Aga-machi, Niigata Prefecture, through the release of organomercury compounds into the Agano River.
Tryptophan contamination
In the late 1980s Showa Denko K.K. decided to change the method it used to produce tryptophan, from fermentation to the genetic engineering of bacteria. Bacteria were engineered to express certain enzymes at much higher levels than normal, and to express other enzymes not normally present in the original bacteria. Because the company had been producing tryptophan for many years via fermentation methods, when production was switched to genetic engineering, no safety testing was deemed necessary. The new tryptophan was placed on the market, and within a few months it caused the deaths of 37 people and caused 1500 more to be permanently disabled. Unfortunately the new tryptophan product was discovered to contain trace amounts of a toxic dimerisation tryptophan product which caused Eosinophilia-myalgia syndrome.
