Organic intermediates
|
|
Sumitomo Chemical offers a wide range of high-value-added
organic chemicals and their derivatives used as raw materials for
various fine chemical products, such as pharmaceuticals, agricultural
chemicals and photographic materials. Furthermore, drawing on our
expertise in organic synthesis, we conduct "custom synthesis" to
tailor specialty chemicals for specific customer requirements.

| |
|
Polymer additives
|
|
|
Our lineup of polymer additives comprises antioxidants, light stabilizers for improving weatherability, and various other high-molecular additives indispensable to polymer production. Our Sumilizer series of antioxidants includes proprietary products such as Sumilizer GM, GS and GA-80. |
|
|
| |
|
Organic rubber chemicals
|
|
We supply a broad range of products including vulcanization
agents, antioxidants, anti-scorching agents and adhesives. Resorcinol,
a chemical intermediate mainly used in adhesives for automobile tires,
is produced using our proprietary process and exported to many countries
around the world.

DYESTUFFS |
 |
|
|
|
|
As a leading Japanese dyestuff manufacturer, Sumitomo Chemical supplies high-quality products both in Japan and overseas. Our extensive product line consists of approximately 600 varieties of dyes and related products, which include disperse dyes for synthetic fibers such as polyester and nylon, and reactive dyes for natural fibers such as cotton and wool. We are particularly strong in reactive dyes. Our Sumifix Supra series of reactive dyes for natural fibers are renowned for their excellent colorfastness and dyeing properties and are well-positioned to meet the growing demand in sportswear and other kinds of apparel.
We are also exploring various new applications for our dyestuffs beyond their conventional use for dyeing fibers. One example of remarkable success in this area is Sumikaron UL, which was developed to dye materials for automobile seats.
To better serve the needs of our customers, we are upgrading our capability for application research and technical service. Such efforts have extended to the development of a proprietary computer-aided color-matching system (SICOMUC), which enables our customers to quickly determine precise dyeing recipes at their laboratories. In addition, we have established distribution and technical service bases for dyestuffs in Singapore, Belgium and the U.S., as well as Japan, to enhance our services for customers around the world. |

Sumitomo Chemical is engaged in the custom synthesis business for pharmaceutical chemicals based on our own state-of-the-art technologies. Today, a number of pharmaceutical companies in the U.S., Europe and Japan are concentrating their efforts on R&D and marketing, while outsourcing bulk pharmaceuticals and intermediates. As a result of these trends, expansion of the custom synthesis market is accelerating. We focus on these business opportunities with our highly sophisticated quality assurance systems as well as current GMP manufacturing facilities for the production of pharmaceutical chemicals, making us a reliable partner in production and technology able to meet our customers' exact needs. |

Related Plants |
|
|
| Osaka Works |
 |
Japan Dyestuffs Manufacturing Company was established in 1916 for the local production of synthetic dyes. It was the predecessor of our Osaka Works, where dyes were synthesized for the first time in Japan. Later the plant expanded into the manufacture of intermediates for dyes and pharmaceuticals. Pharmaceutical bulk production is now a mainstay of the Osaka Works. It has also expanded production into agrochemicals, highly functional polymers, organic rubber chemicals, high polymer additives, electronic chemicals and so on. The Works acts as the main production center for Sumitomo’s specialty chemical business.
It continues efforts to develop new products that will meet diverse customer needs, taking advantage of its location adjoining the research facilities. |

<Utajima Pilot Production Dept.> |
The history of the Utajima Pilot Production Department dates back to 1948, when Sumitomo Chemical invested in the establishment of Yodogawa Pharmaceutical Co., Ltd. for the manufacture of pharmaceuticals. Since then, the Utajima Pilot Production Department has actively undertaken the small-scale production of high value-added products such as new pharmaceutical chemicals and samples for preclinical and clinical studies under contract with various customers both in Japan and abroad. In recent years, it has also taken on the functions of a research facility to transfer the technology for newly developed chemicals to the Okayama and Gifu plants. |
|
| |
<Okayama Plant> |
 |
The Okayama Plant has undergone many changes since it's establishment in 1915 as a producer of dyestuffs for the textile industry, and has now been transformed into a multi-purpose manufacturing facility that is able to produce a wide range of pharmaceutical chemicals. Its production capabilities can accommodate anything from small-scale production of products at the developmental stage to large-scale manufacturing, with reliable quality assurance systems in strict compliance with current GMP. |
|
| |
<Gifu Plant> |
 |
The Gifu plant was established by Sumitomo Chemical in 1971 through an investment in Yodogawa Pharmaceutical Co., Ltd. and has been further developed as a multi-purpose plant for pharmaceutical chemicals. We have been increasing the proportion of high value-added products manufactured at the plant, such as new pharmaceutical chemicals that require advanced quality assurance, proprietary manufacturing processes, and new methods of synthesis. |

Major Affiliated Companies |
|
|
|
|
|
With strengths in organic synthesis and catalyst technology, this company engages in the manufacture and sale of formaldehyde used as the raw material for synthetic resins, polyalcohols used in plastic paints, as well as intermediates for pharmaceuticals and agrochemicals.

The company was incorporated in 1934 as Taoka Dyestuffs Manufacturing Co. and was acquired by Sumitomo in 1955, which then broadened its product range. In 1972, the company name was changed to Taoka Chemical Co., Ltd. Based on its unique organo-synthesis technology derived from dye production, the company produces organic industrial chemicals (fiber modifiers and additives for rubber), adhesives, photochemicals (phtoresist intermediates, photochemical intermediates, heat/pressure sensitive pigment intermediates ) and pharmaceutical and agrochemical intermediates. In the adhesive field, the company launched “Cyanobond,” Japan's first instantaneous adhesive, in 1961, followed by the development of highly functional epoxy base and hot-melt type adhesives, making “Taoka” renowned as a world brand. In October 2000 it merged with Sanken Kako KK, taking over the latter’s plasticizer and varnish businesses. The merger strengthened both the hardware and software of the two operations, which were complimentary to each other. The Company will continue to target world markets in electronics, information/telecommunication, medicine, new materials, etc.

In 1995, Sumitomo Chemical’s domestic dyestuffs sales and technical service groups were reorganized into Sumika Senryotec KK. In 2000, the company took over textile processing resins and paper processing resins sales from Sumitomo Chemical. In April 2001, it signed a distribution contract with Sumitomo to expand its operations into ethylene-vinylacetate emulsion used for adhesive and cement mixing purposes, and was renamed Sumika Chemtex Co., Ltd. It currently acts as Sumitomo chemical's marketing and technical service arm for the above specialty chemicals. In May 2001, the Company started an e-business venture in the dyestuffs market in order to streamline its marketing organization and to remain a strong force in the matured textiles and paper market segments.
