Nouryon recently announced that it is expanding its partnership with Sumitomo Chemical to include a new facility that Sumitomo is building at its site in Oita, Japan. The new plant will supply a key raw material used for Nouryon’s Perkadox 14 organic peroxide.

The plant, to be owned and operated by Sumitomo, will produce 1,3-diisopropanolbenzene (DIOL) and is due to start production in 2021. Sumitomo already supplies Nouryon with DIOL produced at its site in Chiba, Japan.

“We have a strong relationship with Sumitomo, which has supplied DIOL to us from Chiba for the past four years,” said Alain Rynwalt, vice president of Polymer Catalysts at Nouryon. “In response to increased customer demand for our organic peroxides in Asia, we worked with Sumitomo to develop a plant in Oita to help ensure security of supply.”

According to Johan Landfors, president of Technology Solutions at Nouryon, “Asia is a key growth market for Nouryon, and we are continuing to invest in the region to build our presence and to support growing customer demand. This agreement is also a great example of partnering with a supplier to support our strategy of expanding in attractive growth markets.”
