WebMartin’s work was awarded the Army invention of the year. He worked with the U.S. Army Medical Materiel Command to secure two U.S. patents and improve the spray-foam splinting technique. The first patent covers the use of spray foam for combat extremity splinting. The second relates to spray foam for spine immobilization. In the 1940s, researchers, originally at Dow's Chemical Physics Lab, led by Ray McIntire, found a way to make foamed polystyrene. They rediscovered a method first used by Swedish inventor Carl Georg Munters, and obtained an exclusive license to Munters's patent in the United States. Dow found ways to adapt Munters's method to make large quantities of extruded polystyrene as a closed cell foam that resists moisture. The patent on this adaptation was filed in 1947.
