U.S. chemical production improved by its largest margin in nearly four years, according to the latest data from the American Chemistry Council.
The ACC's three-month moving average showed production increased by 4.2 percent between February 2014 and last month, the best rate since July of 2010.
February production also rose by 0.2 percent compared to revised January numbers, the 11th consecutive monthly increase.
Numbers varied, however, between chemical industry segments. Production increased in eight segments, including organic chemicals, consumer products and pharmaceuticals, but decreased in eight others that included synthetic fibers, plastic resins and adhesives.
Last month's numbers also increased despite a slowdown in manufacturing, which was hindered by winter weather and a labor dispute at West Coast ports. Several manufacturing segments that rely heavily on chemicals, however, still saw increases, including electronics, plastics and apparel.
