use of bakelite

Today, only one or two firms now make phenolic resins, but Baekeland's creation set the mold for the modern plastics industry. Bakelite (uncountable) A heat-resisting chemically inert phenol formaldehyde resin … We cannot deny the presence of polymers in our lives. These and other early plastics were made from existing materials. But Baekeland never returned to pure chemistry, or to his roots in Belgium. Like many of the people who have made important contributions to American life, Leo Hendrik Baekeland was an immigrant. Explore the interesting world of science with articles, videos and more. This phenol-formaldehyde resin is a thermosetting polymer. An avid motorist even before automobiles were safe, he toured Europe by car with his family as early as 1907 and spent hours tinkering with car motors. This popular plastic adornment was made in transparent versions, reversed carved, resin washed, and clad with metal among other variations. Bakelite also known as  polyoxybenzylmethylenglycolanhydride is a thermosetting phenol … Explore Career Options Of course, the uses of bakelite were not limited to technological components: buttons, poker chips and pieces of games and toys, firearms, kitchen utensils, electric guitars and even jewellery were made from the material; the new plastic went from filling the gap of a specific demand to boosting industrial development in general. Baekeland's first patent in the field had been granted in 1906; in all, he took out more than 400 patents related to the manufacture and applications of Bakelite. He served as president of the American Institute of Chemical Engineers and the American Electrochemical Society and, in 1924, became the President of the American Chemical Society. But 19th century hunters had virtually decimated the elephant herds of Africa and India, the source of ivory. Very smooth molding can be obtained from this polymer. He first produced a soluble phenol-formaldehyde resin called “Novolak,” which never became a market success. It is a thermosetting polymer and Bakelite has high strength meaning it basically retains its form even after extensive molding. The Achilles heel was color. Identifying by Weight. Uncover the Chemistry in Everyday Life, Recognizing and celebrating excellence in chemistry and celebrate your achievements. Along with its electrical uses, molded Bakelite found a place in almost every area of modern life. Baekeland later decided that "C" and "D" were equivalent. Kleeburg reported a similar experience, describing the substance he produced as a hard amorphous mass, infusible and insoluble and thus of little use. On June 18, 1907, Baekeland began a new laboratory notebook (now in the Archives Center of the Smithsonian's National Museum of American History) documenting the results of tests in which he applied a phenol and formaldehyde mixture to various pieces of wood. I call it Bakalite (sic) and it is obtained by heating A or B or C in closed vessels." Owing to its low electrical conductivity, bakelite is resistant to electric current. Unfortunately, it was quite brittle and had to be strengthened by "filling" with other substances, usually cellulose in the form of sawdust. Phenol and formaldehyde reacted under pressure at high temperature in this sealed autoclave -known affectionately as 'Old Faithful' by early operators - to form the thermosetting resin Bakelite. Explore chemistry education resources by topic that support distance learning. His professional and personal enthusiasm varied widely. The Hyatts made celluloid by applying heat and pressure to a mix of cellulose nitrate and camphor; it was thus a plastic made by modifying natural materials. Bakelite is a unique type of plastic that, similar to gold and silver, makes jewelry valuable. From novelty jewelry and iron handles to telephones and washing-machines impellers, Bakelite was seen everywhere and was a constant presence in the technological infrastructure.

But Baekeland found himself less interested in pure chemistry than in its potential applications, and the two men often quarreled. The Bakelizer, a steam pressure vessel used by Leo Hendrik Baekeland to commercialize his discovery of Bakelite - the world's first completely synthetic plastic. The introduction of Bakelitethe worlds first synthetic plasticin 1907 marked the introduction of the Polymer Age. But they did change history — by inventing celluloid, one of the world's first plastics.
