Huntsman Corporation
A chemical maker whose polyurethane foams, amines, and epoxy adhesives end up in everything from home insulation and car interiors to aircraft and electrical gear. The company traces back to a plastic-packaging venture begun in 1970 by Jon Huntsman Sr., who built his fortune by inventing the Styrofoam egg carton and, later, the clamshell container that held the McDonald's Big Mac.
