Mondo Knows Facts

Bakelite was the first plastic made entirely by people

Leo Baekeland combined phenol with formaldehyde in 1907 to make a hard resin that would not melt again Earlier plastics were derived from cellulose and softened when heated, but Bakelite set into a rigid network that could not be remelted. It was moulded into electrical fittings, radios and telephone handsets because it insulated well and resisted heat. Baekeland's patent described the controlled heating and pressure that made the reaction reliable. It sits in Mondo's technology collection, one of 200 facts that each trace back to the reference below.
