Nanyo, Japan – Tosoh has announced it plans to stop production at its 25kT/year TDI plant in Nanyo in 2023.
The company said that TDI production started at the site in 1962, when it was owned by Nippon Polyurethane Industry Co. Nippon Polyurethane merged with Tosoh in October 2014.
Tosoh added that although it had tried to improve the profitability of the site, business was becoming more difficult. The site makes TDI monomers and derivatives, including dimers, trimers, adhesives and thermosetting resins. This will cease in April 2023.
