The introduction of Bakelite—the world’s first synthetic plastic—in 1907 marked the introduction of the Polymer Age. trademark - a formally registered symbol identifying the manufacturer or distributor of a product A day later, Baekeland listed four different products, designated A, B, C, and D. Substance D was "insoluble in all solvents, does not soften. Bakelite feels heavier when … Kleeburg reported a similar experience, describing the substance he produced as a hard amorphous mass, infusible and insoluble and thus of little use. It was also used in other diverse … In 1880, he used a city scholarship to enter the University of Ghent—the same university at which, only 15 years earlier, August Kekule had described the benzene ring, a discovery that became the cornerstone of modern organic chemistry. Take action: Nominate a Landmark and Contact the NHCL Coordinator. Bakelite may be used for vintage jewelry. He started semi-commercial production in his laboratory and, in 1910, when daily output had reached 180 liters, (most of it for electrical insulators), he formed a U.S. company to manufacture and market his new industrial material. Bakelite is a thermoset plastic commonly found in electronic and automobile components. Today, synthetic plastics are everywhere. Thousands of different polymers exist in nature. American Association of Chemistry Teachers, Reactions: Chemistry Science Videos & Infographics, Man-made Polymers: Invention of Celluloid, Leo Baekeland and the Invention of Bakelite, Biography of Leo Hendrick Baekeland (1863-1944). But to me, Bakelite will always have a special place in the history of plastics as the first truly modern plastic, one that people prized for its beauty, versatility, and durability. When the phenol is taken in excess and the reaction medium is made acidic, the product of the... Bakelite Structure. But no one was able to create a useful product. It is also used to … The lack of records and relevant information precludes any assumption on the extent of its use and in which institutions. This phenol-formaldehyde resin is a thermosetting polymer. Chemists did not fully understand or identify polymers until around 1900. They never received the money. He enjoyed his prosperity by buying two estates—one overlooking the Hudson, north of Yonkers, New York, and a second in Florida—and a yacht which he christened the "Ion." Eventually, they developed a phenol-formaldehyde shellac called Novolak, but it was not a commercial success. Bakelite is the commercial name for the polymer obtained by the polymerization of phenol and formaldehyde. Identifying by Weight. American Chemical Society National Historic Chemical Landmarks. In some instances, several colors were even laminated together. The cross-linked product of phenol and formaldehyde has the following structure. Bakelite definition, a brand name for any of a series of thermosetting plastics prepared by heating phenol or cresol with formaldehyde and ammonia under pressure: used for radio cabinets, telephone receivers, electric insulators, and molded plastic ware. Swarts guided Baekeland through his student years and beyond.

Adapted for the internet from “The Bakelizer,” produced by the National Historic Chemical Landmarks program of the American Chemical Society in 1993. As the future unfolds, plastics and other synthetic polymers will play increasingly versatile roles in medicine, electronics, aerospace and advanced structural composites. He called them "colloids," after "kolla," the Greek word for glue, another material that could not penetrate fine filters. But they did change history — by inventing celluloid, one of the world's first plastics. By 1897, he was a citizen of a new and exciting country, and a visible part of a fledgling chemical industry. Dr. Baekeland's new material opened the door to the Age of Plastics and seeded the growth of a worldwide industry that today employs more than 60 million people. Owing to its low electrical conductivity, bakelite is resistant to electric current. Fortunately, Baekeland's mother, a domestic servant, insisted that he also be allowed to attend a government high school. The next step—the creation of completely synthetic plastic—was still to come. Bakelite jewelry (most of which was originally marketed as Catalin) goes way beyond stacks of bangles in solid colors. Bakelite moldings are heat-resistant and scratch-resistant. By 1887, when the university appointed Baekeland assistant professor of chemistry, Swarts saw it as the start of an illustrious academic career. More than 40 years were to pass before the invention of the first wholly synthetic plastic. Uses of Bakelite… However, specific Bakelite products may require special care, and the following are a few examples of these specific Bakelite products. Bakelite was the first FRP discovered by Dr. Baekeland. See our Browser Support/Compatibility page for supported browsers list. Back to National Historic Chemical Landmarks Main Page. The Polymer Age is also called the Age of Plastics. This popular plastic adornment was made in transparent versions, reversed carved, resin washed, and clad with metal among other variations. Bakelite is a type of plastic that became popular during the first half of the 20th century. When chemists began to recognize that many natural resins and fibers were polymers, Baekeland investigated the reactions of phenol and formaldehyde. Nowadays, Bakelite has been replaced by more modern plastics, and may be the first plastic to achieve vintage status. (Shellac was made from a resin secreted by the East Asian lac bug; it was harvested by the labor-intensive process of scraping the hardened deposits from the trees these insects inhabited.) Some 5,000 years ago, we learned how to make alloys of copper, and the Bronze Age began. Bakelite was also particularly suitable for the emerging electrical and automobile industries because of its extraordinarily high resistance (not only to electricity, but to heat and chemical action as well). He settled in New York City, where the patronage of Columbia University professor Charles F. Chandler led him to a position at a local photographic supply company. In 1870, the American inventor John Wesley Hyatt used chemically modified cellulose to produce an astonishing new product called Celluloid, a plastic that was used for everything from hair combs to silent-movie film. How to Clean Bakelite Door Handles If you have an unclean door handle made of Bakelite, you can use the procedure described above for … At his Snug Rock estate in Yonkers, New York, he maintained a home laboratory where he and his assistant, Nathaniel Thurlow, involved themselves in a variety of projects. His father, a cobbler, opposed his son's wish for an education and apprenticed him at age 13 to a shoemaker. Alternative forms . Yet the surface of the blocks of wood does not feel hard although a small part of gum that has oozed out is very hard. Celluloid not only resembled ivory, it had astonishing properties: at normal temperatures, it was a permanent, hard solid; when heated, it became soft and could be molded or rolled into sheets. The condensation reaction of the two reactants in a controlled acidic or basic medium results in the formation of ortho and para hydroxymethyl phenols and their derivatives. When George Eastman bought the rights to Velox in 1899, Baekeland became financially free to follow whatever scientific pursuits appealed to him. Learn about financial support for future and current high school chemistry teachers. Find awards and scholarships advancing diversity in the chemical sciences. These are one of the oldest polymers that were synthesized by man. It is one of the most common and important polymers that are used to make different parts of many objects. Since it cannot be remelted, the disposal of this material has become an environmental issue. Watch the video below to learn how to test for Bakelite, or skip it and read the same material below the video Safe chemical testing One of the simplest ways to test whether a piece of plastic is in fact Bakelite, is to use a household cleaning product. 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. Like other scientists of their day, Baekeland and Thurlow understood the potential of phenol-formaldehyde resins. Bakelite or polyoxybenzylmethylenglycolanhydride was the first plastic made from synthetic components. Learn More. By 1863, the ivory shortage had become so critical that a New York billiard-ball manufacturer offered a $10,000 prize to the person who could create a useful substitute. Because of its excellent insulating properties, Bakelite was also the first commercially produced synthetic resin, replacing shellac and hard rubber in parts for the electric power industry as … Noun 1. Ultimately, Bakelite was replaced by other plastics that shared its desirable qualities, but could also take bright colors. By 1899, the invention of Velox photographic paper had already made Leo Baekeland a wealthy man. Whereas, when the quantity of formaldehyde taken is more than that of phenol in the reacting mixture, and the reaction occurs in a basic medium, the condensation product is known as Resol. Bakelite® was widely used in the 1920s and 1930s in the United States and Great Britain. Bakelite: Structure and Uses Preparation of Bakelite. Centuries later the Iron Age introduced iron as the material of choice. Some 5,000 years ago, we learned how to make alloys of copper, and the Bronze Age began. The chemical literature included reports written decades earlier by the German chemist Adolf von Baeyer and by his student, Werner Kleeberg. I call it Bakalite (sic) and it is obtained by heating A or B or C in closed vessels." As previously mentioned, Bakelite was used in various industries from automobile and electrical fields. It soon became the material of choice for billiard balls and dozens of other products. Later, as the versatility of Bakelite was explored, a … This led in turn to his first major successful invention, Velox, a new type of photographic paper that would take images using artificial light. Phenolic resins are also extensively used as adhesives and binding agents. He was born in Belgium, in the Flemish city of Ghent, on November 14, 1863. The Achilles heel was color. Learn more. It was there that Baekeland's lifelong commitment to chemistry began. 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. Patented July 1907 by its inventor, Leo Hendrik Baekeland. Bakelite - a thermosetting plastic used as electric insulators and for making plastic ware and telephone receivers etc. This article will explain how originals were made, the simple tests anyone can use to separate genuine Bakelite from look-alike, and the common warning signs of new, fake and reproduction pieces. Bakelite: The World’s First Synthetic Plastic. His professional and personal enthusiasm varied widely. It was soon used for all non-conducting parts of radios and other electrical devices, such as bases and sockets for light bulbs and electron tubes, supports for any type of electrical components, automobile distributor caps and other insulators. Almost anyone can name a dozen familiar products made in part or in whole with plastic: toys, computers, clothing, sports equipment, carpet, appliances, building materials, signs, office supplies, packaging, phones and fashion accessories. And he was a public man: In World War I, Baekeland was appointed to the Nitrate Supply Commission and served as president of the committee on patents of the National Research Council. Nor could these compounds be purified into a crystalline form. 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, the first truly synthetic plastic, a polymer forged entirely in the lab, paved the way for successes like that of DuPont's injection-mold-comb-making son. Most polymers—but not all—consist of monomers that are similar to each other, joined together in a straight chain, like a long string of pearls. By 1930, the Bakelite Corporation occupied a 128-acre plant at Bound Brook, New Jersey. In general, phenol taken in excess acts as the cross-linking agent. The introduction of Bakelitethe worlds first synthetic plasticin 1907 marked the introduction of the Polymer Age. Bakelite (uncountable) A heat-resisting chemically inert phenol formaldehyde resin … Unfortunately, it was quite brittle and had to be strengthened by "filling" with other substances, usually cellulose in the form of sawdust. Polymers ("poly" = many) are very large molecules—veritable giants in the molecular world—comprised of smaller molecules called monomers ("mono" = one). Consider the weight of a piece of plastic jewelry. They are also resistant to several destructive solvents. These characteristics make Bakelite ideal to use for components in electrical parts, such as electrical switches. Bakelite is obtained when Novolac is allowed to undergo cross-linking in the presence of a cross-linking agent. Let ACS help you navigate your career journey with tools, personal coaching and networking. Bakelite's value comes in a different form largely because it's vintage; however, there are fraudulent versions of the material without value. In 1902, German chemist Adolf Luft patented a resin made by modifying Kleeburg's composition in the hope that it could compete commercially with celluloid. I found tube broken perhaps in irregular expansion but the reactions seems to have been satisfactory because the resulting stick was very hard and below where there was some unmixed liquid A there was an end (?) 1155 Sixteenth Street, NW, Washington, DC 20036, USA | service@acs.org | 1-800-333-9511 (US and Canada) | 614-447-3776 (outside North America), Copyright © 2020 American Chemical Society. While at first Bakelite was used for industrial applications because of its electrical insulating properties, it was soon used in manufacturing anything from inexpensive costume jewelry to dinnerware. bakelite; Etymology . The key to reaching the final product "C" from "A" or "B" were machines that subjected earlier stages to heat and pressure. Call for abstracts closes Jan. 19, 2021. It has been aptly named as the ‘Material of a Thousand Uses’. Bakelite applications in conservation were discontinued in the 1940s because of certain disadvantages that soon became apparent. They are further used for protective purposes as well as in the coating industry. 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.

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. Used by Baekeland around 1909, 'Old Faithful' was kept by the General Bakelite Corporation and its successor, Union Carbide Co., which donated it to the Smithsonian Institution in 1983. Phenol is made to react with formaldehyde. Initial methods of preparing bakelite involved the heating of formaldehyde and phenol in the presence of one of the following catalysts -zinc chloride (ZnCl2), hydrochloric acid (HCl), or ammonia (NH3). This looks promising and it will be worth while to determine in how far this mass which I will call D is able to make moulded materials either alone or in conjunctions with other solid materials as for instance asbestos, casein, zinc oxid (sic), starch, different inorganic powders and lamp black and thus make a substitute for celluloid and for hard rubber. They are as familiar to us as wood or metal, and are easily taken for granted. The plaque commemorating the invention reads: The National Museum of American History houses the original Bakelizer, the steam pressure vessel used by chemist-entrepreneur Leo Hendrik Baekeland to commercialize his discovery of Bakelite - the world's first completely synthetic plastic. After a decade of primarily industrial applications, Bakelite soon entered the consumer market. Bakelite definition: 1. a brand name for a type of hard plastic used especially in the past: 2. a brand name for a type…. Like many of the people who have made important contributions to American life, Leo Hendrik Baekeland was an immigrant. Hoping to capitalize on shortages of naturally occurring shellac—used to insulate electrical cables in the early years of the 20th century—Baekeland and Thurlow, as well as several other investigators, were experimenting with soluble resins. We are surrounded by objects, most of which, some way or the other have a polymer associated with them. The ease of molding polymers into different shapes and their relatively low cost of production has been the main reason for their universal usage. Like most immigrants of his day, he wished to be wholly American. Constructed of iron alloys and still structurally sound, the Bakelizer is 35 inches wide, 40 inches deep, and nearly six feet tall. 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. But Baekeland found himself less interested in pure chemistry than in its potential applications, and the two men often quarreled. While tough, Bakelite will … Along with its electrical uses, molded Bakelite found a place in almost every area of modern life. By 1890, Count Hilaire de Chardonnet was marketing the first synthetic textile, Chardonnet silk, made by spinning strands of cellulose nitrate into artificial fiber. Bakelite Bowl with Nutcracker Promoted by Baekeland as "the material of a thousand uses", the first form was moulded, containing phenol formaldehyde, which was used for telephones, light switches, electrical insulators, car parts and many other industrial items. Bakelite is a non-conductive and heat resistant material makes it ideal for electrical insulators. For thousands of years, humans used stone to fashion tools. In order to determine in how far this is possible I have heated in sealed tubes a portion of this liquid so as to determine whether there is a further separation of H2O or whether this is simply a solution of the hard gum in excess of phenol, then by simple open air evaporation I shall be able to accomplish hardening while I shall not succeed in closed sealed tubes. Because Bakelite is easily shaped it is used in many different ways and in many different shapes and sizes. Very smooth molding can be obtained from this polymer. “The Bakelizer” commemorative booklet produced by the National Historic Chemical Landmarks program of the American Chemical Society in 1993 (PDF). The proteins that make up our bodies are polymers, including DNA (deoxyribonucleic acid), the material that carries the genetic codes for all living creatures. Bakelite was the forerunner of the modern plastics industry. USES OF BAKELITE: Bakelite due to its high resistance to electricity and heat is used in automotive components and industrial applications. Also known as Phenolic Laminated Sheets, Bakelite Sheet is double-sided high-pressure laminate, which is well known for its electrical insulation properties and mechanical strength. Today, only one or two firms now make phenolic resins, but Baekeland's creation set the mold for the modern plastics industry. After the 1950s, a large variety of plastics appeared in the marketplace and edged out Bakelite in all but a few specialized (mostly electrical) uses. Your email address will not be published. Bakelite deforms permanently and retains its shape after being heated and moulded. ", Baekeland made the first public announcement of his invention on February 8, 1909, in a lecture before the New York section of the American Chemical Society. I have also heated an open tube rammed with a mixture of asbestos fiber and liquid.
