TOKYO -- Chemical company Tosoh's operating profit probably rose 26% on the year in the April-December 2017 period to around 90 billion yen ($812 million), marking a third straight record. A tighter market for a mainstay chemical product has boosted earnings at the Tokyo-based company.
Tosoh is the Japanese leader in methylene diphenyl diisocyanate, a feedstock for urethane used in synthetic leather, paint and other items.
