U.S. chemical manufacturers’ overall level of activity continued to improve in the second quarter and is expected to improve through the end of the year, according to companies participating in ACC’s quarterly Chemical Manufacturing Economic Sentiment Index survey. ACC’s index, based on companies’ assessment of their activity level overall (e.g., sales, production, output), remained positive in Q2 despite chemical manufacturers reporting weak demand in major customer markets and challenging economic conditions in the U.S. and abroad.
