Nouryon and Sumitomo Extend DIOL Supply Partnership

Published on 2020-03-30. Edited By : SpecialChem

ShoesolesNouryon has announced the expansion of its partnership with Sumitomo Chemical to include Sumitomo’s new plant in Oita, Japan. The plant will supply diisopropanolbenzene (DIOL) to Nouryon.

DIOL - A Key Raw Material for Organic Peroxide


The new plant, to be owned and operated by Sumitomo is due to start production in 2021. Sumitomo already supplies DIOL produced at its site at Chiba, Japan to Nouryon.

DIOL is a key raw material for the production of Nouryon’s Perkadox 14 organic peroxide. Perkadox 14 is an essential ingredient in the manufacture of many elastomeric products, including shoe soles, yoga mats and other rubber goods.

Collaboration to Meet Supply Demand


We have a strong relationship with Sumitomo, which has supplied DIOL to us from Chiba for the past four years. 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 the security of supply,” said Alain Rynwalt, vice president of polymer catalysts at Nouryon.

Nouryon produces Perkadox 14 at Mons, Belgium and at Ningbo, China, where it recently completed an expansion project to increase its production capacity.

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,” said Johan Landfors, president of technology solutions at Nouryon.
