WOODLANDS, Texas—Huntsman Corp. saw sales in its polyurethane division fall slightly in the second quarter of 2013 compared to the same period in 2012, the company said. This was due partly to a loss of production because of a force majeure imposed in Antwerp, Belgium.

In the polyurethane business, revenues fell $16 million from $1,262 million to $1,246 million in the second quarter of 2013 compared to 2012, due to a change in the mixture of products sold. This was offset by slightly higher sales prices. In the first half of 2013, sales decreased $43 million to $2,428 million, compared with $2475 million in the same quarter in 2012.

Methylene diphenyl diisocyanate sales volumes fell in Europe as a result of the force majeure at its MDI facility in Rotterdam, The Netherlands, the company said. The European fall was partially offset by increased sales volumes in the Americas and Asia Pacific regions.

MDI average selling prices increased in all regions in the second quarter of 2013, primarily in response to higher raw material costs.

Polyurethane earnings before interest, tax, amortization and depreciation were unchanged between 2012 and 2013 second quarters at $174 million. In the first half of 2013, profitability was $353 million.
