The origins of Hitachi Chemical can be found in research and development initiatives for electrical insulating varnishes that began in 1912. Since then, the Company has evolved to become the Hitachi Chemical of today, a manufacturer of highly functional material and chemical products, such as laminates, insulators, and carbon brushes, that support manufacturers across the globe.

In 1912, Hitachi, Ltd., began researching electrical insulating varnishes, and successfully created such an insulating varnish in 1914. This was the first varnish of its type to be made in Japan. Insulating varnishes have thus continued to evolve and become more functional, and now, 100 years later, they have come to be used in hybrid electric vehicles while also supporting various other cutting-edge technologies.

1930 Started prototype development of laminates, the predecessors to printed wiring boards

In 1930, Hitachi began prototype development of Phenolic laminates to be used as components in insulating materials as well as machinery. These were the predecessors of the printed wiring boards handled by Hitachi Chemical today.

1931 Began manufacturing insulators

In 1931, Hitachi began manufacturing insulators to be used in substation equipment. The technologies developed through this process have been incorporated into the alumina ceramics and others used today.

1933 Began researching carbon brushes

In 1933, Hitachi began researching carbon brushes. The goal of this endeavor was to create brushes for use with the Japanese-made rotators associated with items imported from Europe and the United States.
The Company's carbon brushes are currently used in a variety of fields including those related to automobiles, trains, and wind power generation.
