With a foundation in organic synthesis and synthetic polymer technologies, catalytic chemistry, Polymer Research Laboratory and environment and energy technology, the Kurashiki Research Center focuses on R&D of new businesses, products and technologies. As the analysis hub of the Kuraray Group, it also conducts global efforts to solve technical issues using analytical and safety evaluation technologies.

1. Establishment
The history of the Kurashiki Research Center began in July 1968 with the establishment of the Central Research Laboratory. At the time, Japanese manufacturers were beginning to establish central research laboratories one after another. Later, there were splits, integrations and transfers as the facility’s role gradually changed with the needs of the times, and in September 2012, it was reorganized into the Kurashiki Research Center, which comprises four research laboratories (for research of synthesis, polymers, analytical technology and solutions, and environment and energy).
2. Characteristics
The Kurashiki Research Center adds new technologies to build on our base of synthesis technologies (organic, polymer and inorganic) accumulated in processes such as the industrialization of isoprene-related products and PVA fiber, the pioneer of synthetic fibers in Japan; catalyst technologies; VA-related polymer technologies; polymer composite technologies; carbon material technologies; and analytical technologies. It also conducts R&D of cutting-edge, novel products and serves as the Kuraray Group’s analysis hub in growth markets such as the environmental, energy, electronics and optics fields.

It originated as the Kuraray Tsukuba Research Laboratories, which was established in April 1994 on the site of World Expo 1985. In 2009, it was renamed the Tsukuba Research Center and established two laboratories (Polymer Materials and Polymer Processing) under the Research and Development Division that create and nurture the seeds of future businesses. In addition, development staff from the Methacrylate Division, Genestar Division, Elastomer Division and other divisions have been assigned to the Tsukuba Research Center, where they are all conducting research under the same roof.
2. Characteristics
The Tsukuba Research Center conducts research and development related to new polymer materials, including acrylic polymers and isoprene polymers, and polymer molding based on composite technology and precision processing technology. Its goal is to create new business in growth markets.
It also functions as the development base for business divisions, and further promotes research and development through information sharing and exchanges with business divisions, the Technology Development Center of the Technology Division, and various other units. Its location in Tsukuba Science City facilitates technological and information exchanges, and its researchers have direct connections to domestic and international markets, making this a research center that is highly sensitive to market needs.
3. Research Content
