Two-page color advertisement for styrene, a chemical compound that is the basis of polystyrene. Dow polystyrene was marketed under the trade name Styron for a variety of commercial and industrial uses. The advertisement features a stylized ribbon of translucent plastic in the center, as well as small inset illustrations showing different applications of styrene. The accompanying text describes the development and uses of styrene in great detail. Notably, styrene was used in the production of synthetic rubber, which became crucial to the United States' war effort after the country no longer had access to natural rubber from Southeast Asia during World War II. The advertisement was produced during World War II and bears the Company's wartime tagline "Dow: Chemicals Indispensable to Industry and Victory."
