DuPont was the world's third largest chemical company based on [[market capitalization]] and ninth based on revenue in 2009. Its stock price is a component of the [[Dow Jones Industrial Average]]. In the 20th century, DuPont developed many [[polymer]]s such as [[Vespel]], [[neoprene]], [[nylon]], [[Corian]], [[Polytetrafluoroethylene|Teflon]], [[Mylar]], [[Kevlar]], Zemdrain, [[M5 fiber]], [[Nomex]], [[Tyvek]], [[Sorona]] and [[Lycra]]. DuPont developed [[haloalkane|Freon]] ([[chlorofluorocarbon]]s) for the cooling industry and later, more [[environmentally friendly]] refrigerants. It developed synthetic [[pigment]]s and [[paint]]s including [[ChromaFlair]]. Some of DuPont's [[trademark]]ed brands have become [[Genericized trademark|genericized]]. For instance, “neoprene” was originally intended to be a trademark, but quickly came into common usage.
