Trailblazing technologies and first-class production capabilities-
Kanto Denka Kogyo leads the development of the digital society.
Advanced materials represented by semiconductors have become essential for the development of society. KDK contributes to a sustainable society through the supply of special materials required by the world’s most advanced technologies.
Through our unique fluorine-related technology cultivated for over half a century, we are able to consistently carry out all processes internally, from refining fluorine gas as a raw material to manufacturing various Specialty Gases.
In addition, we have achieved a diverse product lineup by directly reacting high-purity fluorine gas, which is obtained using our core electrolysis technology, with other raw materials in independent plants dedicated to each product.
We are also working on initiatives such as the introduction of the latest analytical equipment and the establishment of a collaborative development system with semiconductor and equipment manufacturers, making it possible to meet the wide-ranging needs of our customers.
Semiconductors
Specialty Gases are used in film formation, etching, cleaning, and other manufacturing processes.
FPD

In addition to Specialty Gases, which are used in the production process, organic fluorine compounds are used as raw materials.
Optical Fibers
Silicon tetrafluoride is used as a raw material for manufacturing, contributing to performance improvement.
High Capacity Transformers
Sulfur hexafluoride, which has high insulation performance, is used to achieve compact equipment.
