Each Sumitomo Seika laboratory gathers the information necessary for understanding social and market needs, looks ahead to the future without preoccupation with pre-existing ideas, and carries out research and development with new forms of knowledge, which are obtained faster than the competition. We are creating advanced seminal technologies while challenging the existing possibilities of the chemical industry with new ideas. Such researched and developed technologies are shipped from each plant to users both at home and abroad as a unique, high quality, world-class product.
