Nylon has been produced since 1938 (toothbrush bristles and stockings were the first commercial products; it now goes into products ranging from fishing nets to parachutes) and—as already noted—so has Teflon, a ubiquitous non-stick coating. The affordable production of styrene also began during the 1930s, and the material is now mostly used as polystyrene, or PS, in packing materials and disposable cups and plates.
