Neoprene is manufactured around the clock in this DuPont plant at Louisville, Kentucky. The company sells the crude neoprene to rubber product manufacturers who combine it with other ingredients to make a variety of finished goods. When DuPont introduced neoprene in 1932, it sold for $1.05 a pound. Now, due to increased use and improved processes for manufacture, neoprene sells for well under half the original selling price. DuPont also manufactures neoprene at Montague, Michigan.
