The rubber band was patented in England on March 17, 1845, by Stephen Perry. Most rubber bands are manufactured out of natural rubber or, especially at larger sizes, elastomer, and are sold in a variety of sizes. Rubber bands are made by extruding the rubber into a long tube to provide its general shape, putting the tubes on mandrels, curing the rubber with heat, and then slicing it
David Spence (rubber chemistry) Goodrich in 1912. There, he succeeded in synthesizing isoprene for use in synthetic rubber. He left the company in 1914, and started the Norwalk Tire & Rubber Company, where he was vice president and manager until 1925. He retired in 1931, after which he continued to do his own rubber research. During his career, he was responsible for developing several different processes: he developed accelerators for the vulcanization process; a process to devulcanize rubber; a system to extract natural rubber from guayule; and a process to modify the physical properties of rubber. During World War I, Spence headed the National
