Resolving Social Issues with InnovationHistory of Resonac
The history of Resonac, which is creating products and technologies to meet society's needs, is introduced as follows.
Showa Denko Materials
Industrial modernization Japan seeking domestic production
Began research aimed at domestically producing electrical insulating varnishes for motors (origin of former Hitachi Chemical).
Started trial production of phenol resin laminates, porcelain insulators, and carbon brushes.
Began production of "MCL," a copper-clad laminate for multilayer PWBs -- spreading of TVs and radios with the mass production of electronic circuits.
Manufactured Japan's first ammonium sulfate that enabled fertilizer production.
Industrialized domestically produced aluminum.
Established Showa Denko K.K.
Domestically produced synthetic resin emulsions, unsaturated polyester resins, and vinyl ester resins.
Began operation of the Oita Petrochemical Complex -- capable of integrated manufacturing of diverse petrochemical products.
Rapid economic growth development of the electronics industry
Started sales of "PHOTEC," a photosensitive film of alkali-based solvents.
Started production of "ANISOLM," a circuit connecting film for displays.
Entered the hard disk business.
Beginning of the information technology revolution
Started sales of reflow-resistance epoxy molding compounds.
Started mass production of carbon anode materials for lithium-ion batteries
Started production of CMP slurry for shallow trench isolation (STI)
Growing environmental awareness
Started production of molded plastic rear door modules.
Launched the plastic chemical recycling business -- gasifying used plastics to recycle as materials for hydrogen, ammonia, carbon dioxide, dry ice, and other products.
Started production of cooling devices for power semiconductors.
Acquired SGL GE, a German graphite electrode supplier.
Establishment of "Resonac" as a co-creative chemical company
As a "co-creative chemical company" aiming to balance the global environment and people's well-being, Resonac's corporate activities focus on contributing to SDG 12 "Responsible Production and Consumption" and SDG 17 "Partnerships for the Goals."
Semiconductor and electronic materials
Resonac offers semiconductor and electronic materials that contribute to the energy conservation, higher efficiency, and miniaturization of electronic devices enabling 5G and IoT. We provide a wide range of materials from the front- to back-end of semiconductor manufacturing processes with leading global market shares. We also established the "JOINT2" consortium to accelerate the development of cutting-edge materials.
Resonac provides automotive products and lithium-ion battery materials that contribute to the weight reduction and electrification of vehicles as part of the efforts to achieve carbon neutrality. We are particularly focused on the development of xEVs (next-generation vehicles) technologies that utilize our lightweight, electrification, and heat control capabilities.
Innovation enabling materials
Technological innovations of functional materials are essential for a range of next-generation technologies and industries, including the next generation of communications, automobiles, and robots. Resonac is working to develop functional chemicals, resin materials, coating materials, ceramics, aluminum functional materials, and other materials that support various industrial innovations.
Resonac offers such petrochemicals as olefins and organic chemicals, chemicals that include industrial gases and basic chemicals, graphite electrodes, and other products serving as the base and infrastructure for various industries. In the chemical recycling business, hydrogen is extracted from used plastics to produce ammonia and carbon dioxide products that are supplied to hydrogen stations and commercial facilities as part of our co-creative efforts to achieve a low-carbon society.
Resonac combines the strengths of the former Showa Denko's materials technologies and the former Showa Denko Materials' application technologies to pursue new innovations.
