The War Years and the Rise of Plastics and Petrochemicals

Dow’s Depression-Era Strategies Pay Off

During World War II, the research that Willard H. Dow invested in during the Depression resulted in handsome rewards. One of Dow’s first wartime contracts was with the British, who desperately needed magnesium. Dow produced some of this metal at its new plant in Freeport, Texas, which extracted magnesium from seawater. Dow’s production of magnesium became important in fabricating lightweight parts of aircraft. Wartime needs also accelerated the research and production of plastics.

After WWII, Dow had to adapt to the postwar economy. For example, STYROFOAM™ extruded polystyrene, developed as a floating device for the U.S. Coast Guard, was produced globally for thousands of uses, including energy-saving insulation. Dow’s product line was extensive and included chemicals used in almost every conceivable industry. Bulk chemicals accounted for 50 percent of sales and plastics accounted for 20 percent of sales, while magnesium, pharmaceuticals and agricultural chemicals each accounted for 10 percent of sales.
