US: Huntsman Corporation’s Polyurethane division has increased its sales revenue by 9% year-on-year to US$1.98bn in the first half of 2017 from US$1.81bn in the same period in 2016 due to raised prices. It increased its prices of methylene diphenyl diisocyanate (MDI) to counter higher raw material costs and to benefit from a ‘strong’ market. However, sales volumes of MDI decreased in the reporting period due to maintenance outages. This caused its divisional adjusted earnings before interest, taxation, depreciation and amortisation (EBITDA) to fall in the second quarter of 2017 although it rose as a whole for the half year. Amongst other products the chemical manufacturer produces polyurethane, which is used by the insulation industry.
