Main Products
Polarizing Films
-
Polarizing films "SUMIKARANTM"
Polarizing films are essential for LC and OLED displays. They help enhance the brightness, contrast, viewing angle and other performances of the display.
Touch screen sensor panels
-
Touch screen sensor panels
Touch sensor displays are very popular in mobile equipment. A touch screen sensor panel plays a key role in the display by detecting the finger touch as electric signals. It is an sophisticated sensor device for which high position accuracy and high sensitivity are required.
Color Resists
-
Color Resists "DyBrightTM"
The color characteristics of LC and OLED displays depend on the color filter. Our color resists that have been developed based on our proprietary dye technology ensure high brightness and wide color gamut of color filters.
Photoresists
-
Photoresist "SUMIRESISTTM"
Photoresists are photosensitive resins used in the production of high-density, highly integrated circuit patterns on semiconductors and printed boards. Our photoresists respond not only to the needs of latest front-end process but also to the recent sophistication of the back-end process of semiconductor production.
Aluminum Sputtering Targets
-
Aluminum Sputtering Targets
Sumitomo Chemical is the world's only manufacturer that produces aluminum sputtering targets from raw materials to the final products. We offer high quality aluminum targets by combining our original crystal control technology with ultra-high purification technology that we have developed over many years of aluminum refining.
Produced under strictly controlled conditions, our aluminum targets are highly evaluated for their high quality, reliability, and excellent cost performance in semiconductors, displays, and other applications.
Compound Semiconductor Materials
-
Compound Semiconductor Materials
Compound semiconductors are used for antenna switches and laser diodes of communication terminals in this age of IoT. They are increasingly used because of their advantages in speed and breakdown voltage over silicon semiconductors. We provide gallium arsenide (GaAs), gallium nitride (GaN) and other materials required in compound semiconductors.
High Purity Alumina(HPA)
-
High Purity Alumina
We supply specialty alumina with a purity of over 99.99%. High-purity alumina is used for lithium-ion secondary battery materials and ceramic parts of semiconductor manufacturing equipment.
High Purity Aluminium
-
Ultra High Purity Aluminium cut wire and rolled products
We produce Ultra High Purity Aluminium (up to 99.9999%) usedin highly functional products, such as flat panel displays, wiring materials for semiconductors, and heattransfer materials for cryogenic application.
Super Engineering Plastics
-
Super Engineering Plastics
Super engineering plastics are high-performance resins that have excellent heat resistance, strength, chemical resistance, and processability. As materials that meet the needs for lighter and finer articles, super engineering plastics include liquid crystalline polymer, which is used in the manufacture of electrical and electronic products and is expanding into applications in the industry and automobile areas, and polyethersulfone, which, in addition to electrical and electronics applications, is also being used as a carbon fiber composite in aircraft, as a high-performance separation membrane material, and as a heat-resistant coating.
Resorcinol
-
Resorcinol
This material is used in the manufacture of tires, wood adhesives, flame retardants, and ultraviolet ray absorbants.
Lithium-ion secondary battery materials
-
Separator "PERVIOTM"
A lithium-ion secondary battery comprises a cathode, an anode, and a separator that electrically insulates these two sheets from one another to prevent a short circuit. Sumitomo Chemical is expanding its business in separators.
-
Osaka Works
Japan Dyestuffs Manufacturing Company, the predecessor of the Osaka Works, was established in 1916 for the domestic production of synthetic dyes, eventually becoming the largest dyestuffs manufacturing company in Japan. In 1944, this company was merged with Sumitomo Chemical and became the Osaka Works. Since then, it has been continuously delivering useful technologies and new products in response to the needs of the times. The Osaka Works has developed as the core for the manufacture of fine chemical products. At present, the Osaka Works produces photoresists, agricultural chemicals and polymer additives by leveraging the technologies it has developed, while working closely with a research laboratory located on the same premises to meet diverse customer needs.

Ohe Works
Ohe Works
Main Products
Polarizing films (SUMIKALANTM), and Separator for Lithium-ion Secondary Batteries
In April 2009, the Ohe Works was established as a manufacturing and assembly plant in the Ohe district of our Ehime Works, where we have been producing optical functional films and our separator for lithium-ion secondary batteries. In cooperation with the adjacent ICT & Mobility Solutions Research Laboratory, the Quality Assurance Office of the ICT & Mobility Solutions Sector, and the Optical Materials Division, the Ohe Works has worked to build manufacturing and technological capabilities and also gather the talent and technology ideally suited for the field of manufacturing and assembly in order to strengthen the competitiveness of our existing businesses and enter new business fields to support the further development and growth of the manufacturing and assembly business of Sumitomo Chemical and the Sumitomo Chemical Group.
-
Ibaraki Works
With the starting point of research into GaAs (Gallium Arsenide) crystal growth in 1971, we established works in this location in 1987 and have cultivated crystal growth technology, process technology and evaluation technologies for over 50 years. In October 2022, Sumitomo Chemical's Ibaraki Plant was established through the absorption merger, and have supported the development of the compound semiconductor materials business and the actions of the global production and development. We will contribute to the realization of a sustainable society by providing best compound semiconductor materials for solving social issues.
