View of a female model lifting a log of Dow Chemical Company Styrofoam over her head to demonstrate the product's buoyant and lightweight properties. Several stacks of Styrofoam logs are visible in the background. Invented in 1941 by researchers in Dow's Chemical Physics Lab, "Styrofoam" properly refers to the Dow Chemical Company’s trademarked brand of closed-cell extruded polystyrene foam commonly used for thermal insulation and craft applications.
