Wilmington, the Chemical Capital of the World
Few cities are as closely tied to the chemical industry as Wilmington. In 1802, E. I. du Pont founded a gunpowder mill on the Brandywine Creek, launching a company that would become one of the most influential chemical enterprises in history. Over the following two centuries, DuPont scientists in Wilmington invented nylon, neoprene, Teflon, Kevlar, and countless other materials. The company's success attracted talent and spawned many other businesses, giving Wilmington its reputation as the Chemical Capital of the World.
Today, the region remains home to several global chemical headquarters and major research and manufacturing sites. Here are ten of the most important chemical companies in the Wilmington area.
