[9] Producing hard, compact, insoluble and infusible condensation products of phenols and formaldehyde marked the beginning of the modern plastics industry. Aylesworth, and the Redmanol Chemical Products Company, founded by L.V. Hydrochloric acid is added drop by drop by continuous stirring. This variety includes clear material, for jewelry, smokers' articles, etc. During the moulding process, the manufacturer could add materials to change the colour and translucency of the Bakelite. Translucent jewelry, poker chips and other items made of phenolic resins were introduced in the 1930s or 1940s by the Catalin company under the Prystal name. Bakelite Corp. was formed in 1922 from General Bakelite Co., Condensite Corp. and Redmanol Co. In recent years the "retro" appeal of old Bakelite products has made them collectible. The creation of a synthetic plastic was revolutionary for its electrical nonconductivity and heat-resistant properties in electrical insulators, radio and telephone casings and such diverse products as kitchenware, jewelry, pipe stems, children's toys, and firearms. That means once a Bakelite product is formed, it will not change shape or melt under heat. [42] Designer Coco Chanel included Bakelite bracelets in her costume jewelry collections. [5][6] It was the first synthetic thermosetting plastic produced, and Baekeland speculated on "the thousand and one ... articles" it could be used to make. Options (a) aromatic nucleophilic substitution (b) aromatic electrophilic substitution (c) condensation (d) electrophilic addition. [25], Bakelite phenolic sheet is produced in many commercial grades and with various additives to meet diverse mechanical, electrical and thermal requirements.

[40] It was soon found in myriad other consumer products ranging from pipe stems and buttons to saxophone mouthpieces, cameras, early machine guns, and appliance casings. Important projects included the Liberty airplane engine,[34] the wireless telephone and radio phone,[35] and the use of micarta-bakelite propellors in the NBS-1 bomber and the DH-4B aeroplane. Formation of Novalac from ortho hydroxy benzyl alcohol. [63], By the late 1940s, newer materials were superseding Bakelite in many areas. Studying the properties of Bakelite will give us a wider idea as to why it is used for a wide range of applications. Plastics formed from other formulas can be reshaped after reheating or will burst into flame if reheated. (Note: in the answers below the hydroxymethyl group is -CH 2 OH.) View Bakelite Formation PPTs online, safely and virus-free! Chemists already knew about polymers, compounds formed by chains of repeated units that lent themselves to this type of manipulation, but those present in nature were not satisfactory. The results for 3 mm thick plates are presented in Fig. This page was last edited on 12 January 2021, at 22:57. [10] He announced his invention at a meeting of the American Chemical Society on February 5, 1909. Some quantity of reaction mixture is taken in a beaker and placed on a white paper towel. C) ortho and para-(hydroxymethyl)phenol The components are big and clunky (induction coil upper left - capacitor upper right). [62], Bakelite was sometimes used as a substitute for metal in the magazine, pistol grip, fore grip, hand guard, and butt stock of firearms. The first step in bakelite formation is . In 1932, the phenolic resin business of Sankyo Co., Ltd. was separated and formed Nippon Bakelite Co., Ltd. History: HOW DO I KNOW IF IT IS BAKELITE? Bakelite resin could be provided either as powder, or as preformed partially cured slugs, increasing the speed of the casting. So, we can, in general, say that Bakelite is a condensation polymer or a phenolic resin. Based on the above-mentioned properties of the Bakelite, here are some of its uses-. These included other types of cast phenolic resins similar to Catalin, and urea-formaldehyde resins, which could be made in brighter colors than polyoxy­benzyl­methylene­glycol­anhydride.[3][7]. Chemists had begun to recognize that many natural resins and fibers were polymers. Centuries later the Iron Age introduced iron as the material of choice. Plastics formed from other formulas can be reshaped after reheating or will burst into flame if reheated. Beginning in the 1920s, it became a popular material for jewelry. The wiring is in a laced loom and nicely formed. As we now know the Bakelite preparation method as well as its structure, let us now have a look at the properties of Bakelite. So, we can, in general, say that Bakelite is a condensation polymer or a phenolic resin. Bakelite continues to be used for wire insulation, brake pads and related automotive components, and industrial electrical-related applications. Description: Bakelite is an early plastic. How is Bakelite formed? The Bakelite preparation can be demonstrated in the following steps of reactions-. Baekeland's initial intent was to find a replacement for shellac, a material in limited supply because it was made naturally from the excretion of lac insects (specifically Kerria lacca). The colorful bangles, earrings and bracelets were widely used. For thousands of years, humans used stone to fashion tools. It is a thermosetting phenol-formaldehyde resin formed by the condensation reaction of phenol with formaldehyde. When it was first introduced, Bakelite revolutionized the jewelry industry and took the fashion world by storm. Bakelite is a condensation polymer of formaldehyde and phenol. Bakelite jewelry has been around for decades and is known for being inexpensive and versatile. History is shaped by the materials we develop and use. It can be colored, molded, cut, drilled, and formed. Bakelite is a fast-setting red-colored phenol resin, which after being released in liquid form will quickly harden. It … [64] Soviet heatshields for ICBM warheads and spacecraft reentry consisted of asbestos textolite, impregnated with Bakelite. We may not realize but we live in a world of polymers, and everything and anything connected to us or our surroundings is chemistry. [65] Bakelite is also used in the mounting of metal samples in metallography. It was made in 1907 by Belgian chemist Leo Baekeland. Aylesworth; and the Redmanol Chemical Products Company, founded by Lawrence V. Bakelite jewelry became immensely popular in the 1920s as an affordable and attractive replacement for other materials. Bakelite jewelry has been around for decades and is known for being inexpensive and versatile. Bakelite is made by the reaction between formaldehyde and phenolic materials at high temperatures; the substance is hard, infusible, and chemically resistant (the type known as thermosetting plastic). Bakelite was the major form of “art plastic” from the 1930s through to the 1950s. Good mechanical and impact strength with continuous operating temperature of 250 °F (120 °C). It was developed by the Belgian-American chemist Leo Baekeland in Yonkers, New York, in 1907. The first factory was built near Bound Brook, New Jersey, in 1929 and production for the product ramped up from that point. It was developed by the Belgian-American chemist Leo Baekeland in Yonkers, New York, in 1907. Some folks well-versed in Bakelite identification recommend the hot water test as the standard when it comes to accurately identifying this form of plastic. “Bakelite Food Processing Pvt Ltd” a renowned name in Bakery products is situated in Pune district of Maharashtra. The curing procedure that is required to make Bakelite is known as a thermosetting process - it is irreversible once the polymer has formed, unlike thermoplastics which can be melted and re-shaped. That was an understatement. Bakelite (and Galalith before it) introduced plastics to the … 12's fitted as well. Several sales and mergers took place in the 1960s and 1970s, in 1973 Distillers Co. sold its 50% stake to Union Carbide. The principal characteristic of these materials is the wide range of colours possible, including many intense bright colours. Different substitutes of phenol and formaldehyde can also be used depending on the application. Since Bakelite is a manufactured, synthetic plastic containing incredible amounts of formaldehyde, asbestos and other extremely toxic polymers, those who produced these desirable products, put themselves at risk. [7][31] By 1912, it was being used to make billiard balls, since its elasticity and the sound it made were similar to ivory. Bakelite falls under this category of plastics. When it was first introduced, Bakelite revolutionized the jewelry industry and took the fashion world by storm. By 1912, molding material was gaining ground, but its sales volume for the company did not exceed that of laminating varnish until the 1930s. The structure for the cross-linked polymer, known by the commercial name of Bakelite is given below. It is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. In the formation of Bakelite, the reaction mixture is prepared by mixing formaldehyde with phenol with glacial acetic acid under fume hood. Known as a cast phenol formaldehyde resin, Catalin, created in 1927, is a thermosetting polymer not unlike Bakelite, except the production is in two stages, where Bakelite requires more of a … Bakelite is a thermosetting resin; a polymer formed by the reaction of phenol and formaldehyde. It is one of the first plastics made from synthetic components. ; lacquers, for protecting the surface of hardware; enamels, for giving resistive coating to industrial equipment; Laminated Bakelite, used for silent gears and insulation; and molding material, from which are formed innumerable articles of utility and beauty. Bakelite is an early plastic. Common dice are sometimes made of Bakelite for weight and sound, but the majority are made of a thermoplastic polymer such as acrylonitrile butadiene styrene (ABS). It has been widely used both alone, to form whole objects, and in combination with … The colorful bangles, earrings and bracelets were widely used. Bakelite bā´kəlīt [for its inventor, L. H. Baekeland], synthetic thermosetting resin. The new Ericsson telephone was completely formed in Bakelite with the cradle integrated in the actual casing. *****Percy Faith & His Orchestra***** The kitchen is the heart of the home….. Bakelite is an early plastic. The heat from the water releases the formaldehyde-like scent of Bakelite. Before it has set, the resin can be cast in a mould; once set, it is hard enough to be drilled, and does not soften again or deform when heated. Bakelite is made from carbolic acid (phenol) and formaldehyde and is referred to as a phenolic resin. [28] When rubbed or burnt, Bakelite has a distinctive, acrid, sickly-sweet or fishy odor. [17] The article emphasized that Bakelite came in various forms. Bakelite was patented on December 7, 1909. Bakelite is the commercial name for phenol formaldehyde resin. The plastic furniture at homes, offices and schools, the electric sockets, plugs, devices, buckets- everything has become an essential part of human life. Bakelite is formed by the acid-catalyzed polymerization of phenol with formaldehyde. B) meta-hydroxybenzaldehyde. Water molecule is removed in the process. Bakelite Bakelite was the forerunner of the modern plastics industry. Asbestos, wood flour, cotton flock, cotton pulp, gypsum, mica etc., are a few reinforcing fillers that are added in molding resins like Bakelite. Some common types include:[26], Bakelite has a number of important properties. Correct Answer: aromatic electrophilic substitution. It cannot be remelted to form a new product and so … Unfortunately, the additives dulled the hue colorized Bakelite. The cloth is also made with cellulose paper, synthetic yarn, cotton, glass fabrics, or unwoven fabrics. [3], Bakelite was designated a National Historic Chemical Landmark on November 9, 1993, by the American Chemical Society in recognition of its significance as the world's first synthetic plastic. Today, Bakelite is still produced in sheet, rod and tube form for industrial applications in the electronics, power generating and aerospace industries. Bakelite is a trade name of the phenol-formaldehyde resin, which is one of the earliest synthetic polymers. A new Bakelite factory opened in Tyseley, Birmingham, England around 1928. The integrated sculptural form departed from the more additive, engineer oriented design of the plate era. [53][54] By 1935, it was used in solid-body electric guitars. Bakelite has emerged out as a huge commercial success and its uses know no boundaries. He formed the General Bakelite Company as a U.S. company to manufacture and market his new industrial material. Bakelite (/ˈbeɪkəlaɪt/ BAY-kə-lyte; sometimes spelled Baekelite) or polyoxybenzylmethylenglycolanhydride was the first plastic made from synthetic components. In England, Bakelite Limited, a merger of three British phenol formaldehyde resin suppliers (Damard Lacquer Company Limited of Birmingham, Mouldensite Limited of Darley Dale and Redmanol Chemical Products Company of London), was formed in 1926. E.g., PVC. We know that resin today as Bakelite, named after its inventor, Leo Baekeland, the chemist whose process was patented in 1909. While technically known as a “phenolic plastic”, the main issue with Bakelite was that it was notoriously brittle. What is(are) the product(s) of the first step in this polymerization, shown below? Redman. Acrylic plastic refers to a family of synthetic, or man-made, plastic materials containing one or more derivatives of acrylic acid. It is the 21st century and we literally live in the world of plastics. Bakelite was also very commonly used in making molded grip panels (stocks) on handguns, submachine guns and machineguns, as well as numerous knife handles and "scales" through the first half of the 20th century.[41]. [7]:42–43, Another market for Bakelite resin was the creation of phenolic sheet materials. Bakeland formed his new company Bakelite Corporation in 1922. Bakelite is sometimes used for saucepan handles, parts for electric irons, electrical plugs and switches and in disc brakes for cars. "[61], In 1947, Dutch art forger Han van Meegeren was convicted of forgery, after chemist and curator Paul B. Coremans proved that a purported Vermeer contained Bakelite, which van Meegeren had used as a paint hardener. It begins with heating of phenol and formaldehyde in the presence of a catalyst such as hydrochloric acid, zinc chloride, or the base ammonia. These are one of the oldest polymers that were synthesized by man. The resulting substance is extremely hard and both infusible and insoluble. During the moulding process, the manufacturer could add materials to change the colour and translucency of the Bakelite. The two major classifications of plastics are- Thermoplastics and Thermosets. Bakelite is a synthetic resin chemically formulated and named after its Belgian inventor, Chemist L.H.Baekeland c.1909.It is pronounced "Bay Ka Lite". Bakelite was the first thermosetting plastic. Bakelite was fairly brittle in its pure form. ; cement, using in sealing electric light bulbs in metal bases; varnishes, for impregnating electric coils, etc. Items such as billiard balls, dominoes and pieces for board games such as chess, checkers, and backgammon are constructed of Bakelite for its look, durability, fine polish, weight, and sound. Bakelite made perhaps its largest stamp on the world of fashion. Thermosets or thermosetting plastics on the other hand become hard and rigid on cooling and retain their shape. PMMA is a tough, highly transparent material with excellent resistance to ultraviolet radiation and weathering. In this method, the piece of plastic is placed under very hot running tap water. [7]:58–59 Baekeland considered the possibilities of using a wide variety of filling materials, including cotton, powdered bronze, and slate dust, but was most successful with wood and asbestos fibers. It is a thermosetting phenol formaldehyde resin, formed from an elimination reaction of phenol with formaldehyde. [66], Bakelite items, particularly jewelry and radios, have become a popular collectible. Continuous operating temperature 250 °F (120 °C). Bakelite is a sturdy material and is heavier than Celluloid. Pro Lite, NEET It’s a type of plastic that can be formed into various designs. [9] Baekeland also filed for patent protection in other countries, including Belgium, Canada, Denmark, Hungary, Japan, Mexico, Russia, and Spain. Collectors prize genuine Bakelite products originally marketed to the middle and lower classes because it was cheap to make and sell. Bakelite Limited was formed in 1927 from the amalgamation of three suppliers of phenol formaldehyde materials: the Damard Lacquer Company Limited of Birmingham; Mouldensite Limited of Darley Dale and Redmanol Limited of London. Everyone seemed to be wearing Bakelite at some point in the last century. Bakelite was the first thermosetting plastic. Traffolyte is formed by similar processes and yet, it is much more resilient and malleable. Some examples of polymers are polythene, bakelite, rubber, etc. [40] Phenolics are less frequently used in general consumer products today due to their cost and complexity of production and their brittle nature. It is a thermo-setting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. In practice, the phenol and formaldehyde are first polymerized to a small extent by using the proper choice of catalyst and temperature. [12]:172–174 Blocks or rods of cast resin, also known as "artificial amber", were machined and carved to create items such as pipe stems, cigarette holders and jewelry. Authentic bakelite jewelry can sell for thousands of dollars, so it's important you learn how to tell the difference between genuine and imposter plastic jewelry. Plastics formed from other formulas can be reshaped after reheating or will burst into flame if reheated. [7]:43[30] Bakelite was soon used for non-conducting parts of telephones, radios and other electrical devices, including bases and sockets for light bulbs and electron tubes (vacuum tubes), supports for any type of electrical components, automobile distributor caps and other insulators. The company was acquired by Union Carbide and Carbon Corp. in 1938. The British children's construction toy Bayko, launched in 1933, originally used Bakelite for many of its parts, and took its name from the material. [7]:44–45[24][27], Phenolic resin products may swell slightly under conditions of extreme humidity or perpetual dampness. To make it more malleable and durable, it was strengthened with additives. They still appear in some applications where their specific properties are required, such as small precision-shaped components, molded disc brake cylinders, saucepan handles, electrical plugs, switches and parts for electrical irons, as well as in the area of inexpensive board and tabletop games produced in China, Hong Kong and India. BAKELITE was the first plastic made from synthetic components. Bakelite resin is a phenol formaldehyde resin formed by condensation reaction of phenol or substituted phenol with formaldehyde. These are one of the oldest polymers that were synthesized by man. Used in all manner of electrical devices, household objects, appliances and decorative items. The addition of an inert filler also reduces the cost of molding. Baekeland produced a soluble phenol-formaldehyde shellac called … Bakelite is a thermoset plastic which is formed from an elimination reaction of phenol with formaldehyde and it is most commonly used for automobile parts, telephone casings, and kitchenware appliances for heat resistant. It is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. [57][58] In 1943, the thermosetting phenolic resin was even considered for the manufacture of coins, due to a shortage of traditional material. Bakelite is a thermosetting phenol formaldehyde resin, formed from elimination reaction of phenol with formaldehyde. During World War II, Bakelite was used in a variety of wartime equipment including pilot's goggles and field telephones. Baekeland's initial intent was to find a replacement for shellac, a material in limited supply because it was made naturally from the excretion of lac insects (specifically Kerria lacca). Bakelite is made from carbolic acid (phenol) and formaldehyde and is referred to as a phenolic resin. History: The formaldehyde family of resins are highly cross-linked polymers formed by condensation reactions. When other plastics that followed were found to hold their color better, Bakelite was abandoned. We see that a number of things like the plastic handle of utensils, telephones, bangles, automobile parts etc., are made of Bakelite. The molding material is prepared ordinarily by the impregnation of cellulose substances with the initial 'uncured' resin. It is a thermosetting phenol-formaldehyde resin formed by the condensation reaction of phenol with formaldehyde. Fillers are used to increase the strength and enhance the properties of the Bakelite so that it can be used for various applications. [12] As of 1911, the company's main focus was laminating varnish, whose sales volume vastly outperformed both molding material and cast resin. [4], Baekeland then began experimenting on strengthening wood by impregnating it with a synthetic resin, rather than coating it. "[15]:17 In a 1925 report, the United States Tariff Commission hailed the commercial manufacture of synthetic phenolic resin as "distinctly an American achievement", and noted that "the publication of figures, however, would be a virtual disclosure of the production of an individual company".[18]. Versatile, durable and colourful, Bakelite once formed part of everyday life for millions of people, but collectable examples are now scarce. 10 to 12ml of conc. The most common acrylic plastic is polymethyl methacrylate (PMMA), which is sold under the brand names of Plexiglas, Lucite, Perspex, and Crystallite. Share yours for free! It was developed by the Belgian-American chemist Leo Baekeland in Yonkers, New York, in 1907. When heat and pressure are applied, polymerization transforms the layers into thermosetting industrial laminated plastic. A new factory opened in Bound Brook, New Jersey, in 1931.[7]:75. It is a thermosetting phenol formaldehyde resin, formed from an elimination reaction of phenol with formaldehyde. [11], Baekeland started semi-commercial production of his new material in his home laboratory, marketing it as a material for electrical insulators. Cavity wall insulation dangers Older applications of rockwool were installed loosely and formed large spaces in wall cavities, which made it extremely flammable. [14] Under director of advertising and public relations Allan Brown, who came to Bakelite from Condensite, Bakelite was aggressively marketed as "the material of a thousand uses". Sustained heating results in an "insoluble hard gum". [39][67], The United States Patent and Trademark Office granted Baekeland a patent for a "Method of making insoluble products of phenol and formaldehyde" on December 7, 1909. These properties make it ideal for many applications including airplan… Following are a few properties that are enhanced by the addition of fillers: Greater thermal, electrical and chemical resistance. This creates a liquid condensation product, referred to as Bakelite A, which is soluble in alcohol, acetone, or additional phenol. Thermosetting meant that it could not be melted or changed by heating once formed. It was manufactured in the first decade of the 20th century and found various applications. Good mechanical and electrical strength. These included Bakelite buttons used in both Army (brown colored) and RAF (black) BD uniforms. Bakelite can be gathered by destroying Bones which can be found in the Desert. So, we can, in general, say that Bakelite is a condensation polymer or a phenolic resin. [36][37], Bakelite's availability and ease and speed of molding helped to lower the costs and increase product availability so that telephones and radios became common household consumer goods. What are the Desirable Properties of Bakelite? Bakelite and other non-metal materials were tested for usage for the one cent coin in the US before the Mint settled on zinc-coated steel. It is a thermosetting phenol formaldehyde resin, formed from an elimination reaction of phenol with formaldehyde. The ability to be molded makes it a part of the commodities being used in modern life. Since Bakelite can be made into different colors, Bakelite jewelry was once very much in use. [7]:58–59[15] A filing for a trademark featuring the letter B above the mathematical symbol for infinity was made August 25, 1925, and claimed the mark was in use as of December 1, 1924. It is also resistant to electricity, and prized for its low conductivity. Initially products were sold under the brand name ‘Maharaja Gold’. Moldings are smooth, retain their shape and are resistant to heat, scratches, and destructive solvents. It was patented by Belgian born Leo Hendrik Baekeland in New York, in 1907, and was the first truly synthetic and thermosetting plastic. The range of colors available included "black, brown, red, yellow, green, gray, blue, and blends of two or more of these". A) ortho and para-hydroxybenzaldehyde. You may also find Dial No. About 110 years ago, the plastics era (as we understand that term) began with a material called Bakelite named by its creator and inventor Leo Baekeland. Because molded Bakelite incorporated fillers to give it strength, it tended to be made in concealing dark colors. [40], Phenolic resins have been commonly used in ablative heat shields.
