Founded as a fertilizer company in 1944, Sumitomo Seika shifted its core business to industrial chemicals during a period of instability in the fertilizer industry. It has since continued to pursue research and development based on its technology base, establishing current core businesses in the areas of absorbent polymers, functional chemicals, and gases. The Sumitomo Seika Group seeks to be a company that continues to grow globally and contribute to society.

Sumitomo Seika is a chemical company offering products with unique functions.
