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. "Bakelite" and "Parkesine" are both synthetic resins named after their inventors. The plastic was even under consideration by the United States Mint as a replacement for copper in making pennies. Bakelite continues to be used for wire insulation, brake pads and related automotive components, and industrial electrical-related applications. This creates a liquid condensation product, referred to as Bakelite A, which is soluble in alcohol, acetone, or additional phenol. Baekeland invented it in the early 1900s. The result is a hard plastic material. Phenolic resins are also extensively used as adhesives … [3]:67 [7]:38–39, Molded Bakelite forms in a condensation reaction of phenol and formaldehyde, with wood flour or asbestos fiber as a filler, under high pressure and heat in a time frame of a few minutes of curing. Wikibuy Review: A Free Tool That Saves You Time and Money, 15 Creative Ways to Save Money That Actually Work. Bakelite® was widely used in the 1920s and 1930s in the United States and Great Britain. Formed by the reaction under heat and pressure of phenol and formaldehyde, generally with a wood flour filler, it was the first plastic made from synthetic polymers. [47][48] Kitchenware made with Bakelite, including canisters and tableware, was promoted for its resistance to heat and to chipping. 1. Collectors prize genuine Bakelite products originally marketed to the middle and lower classes because it was cheap to make and sell. Some 5,000 years ago, we learned how to make alloys of copper, and the Bronze Age began. Thermosetting resins such as Bakelite required heat and pressure during the molding cycle, but could be removed from the molding process without being cooled, again making the molding process faster. MY BAKELITE LECTURE/TALK is now available !!! On 7 December 1909, the United States Patent and Trademark Office granted the Belgian-born chemist Leo Baekeland a patent for a “Method of making insoluble products of phenol and formaldehyde”. Bakelite is a plastic that is used for making many products, ranging from telephones, electrical gadgets, jewelry, to saucepan handles. Bakelite is a brand-name material developed in 1909 by Dr. Leo Baekeland. [13] 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". A new Bakelite factory opened in Tyseley, Birmingham, around 1928. 1 ; It is a type of thermosetting plastic whic is a poor conductor of heat and electricity.

The New York Times hailed the new material as an economical replacement for celluloid and hard rubber. Because molded Bakelite incorporated fillers to give it strength, it tended to be made in concealing dark colors. Bakelite is used in making electrical appliances because it has very good electrical insulating properties. ! Due to its excellent insulating properties it is used for making switches and other electrical appliances. Experimenting with various pressure and temperature settings, he discovered a moldable plastic that became very hard when cooled and dried. Redman. As the sales figures also show, the Bakelite Company produced "transparent" cast resin (which did not include filler) for a small ongoing market during the 1910s and 1920s. [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. Share with your friends. Phenolic resins are the result of a condensation reaction of phenol and formaldehyde. Also, because of the smooth polished surface that resulted, Bakelite objects required less finishing. 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. And so "Faturan", named after its original inventor, became a brand of cast thermosetting phenol formaldehyde resin, similar to Bakelite and Catalin, manufactured by Traun & Son of Hamburg., developed in the early 20th century, and produced until the 1940s. In 1939, the companies were acquired by Union Carbide and Carbon Corporation. [4], Baekeland was already wealthy due to his invention of Velox photographic paper when he began to investigate the reactions of phenol and formaldehyde in his home laboratory. While tough, Bakelite will develop a hazy or dull finish when exposed to the elements. 5 ; View Full Answer bakelite is a plastic and also a poor conductor of electricity. 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. [11] As of 1911, the company's main focus was laminating varnish, whose sales volume vastly outperformed both molding material and cast resin. When heat and pressure are applied, polymerization transforms the layers into thermosetting industrial laminated plastic. Bijker gives a detailed discussion of the development of Bakelite and the Bakelite company's production of various applications of materials. [49][50] In the mid-1930s, Northland marketed a line of skis with a black "Ebonite" base, a coating of Bakelite. This makes it possible to design any contour for efficient breaking of arc / current. 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 is an old trade name for Phenolic thermoset plastic which was developed by Leo Bakeland about 100 years ago. [38] 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. The use of this material declined after World War II, when lighter and more colorful plastics were developed. 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]. Bakelite could be used for electric insulators or as an insulating coating for automotive wiring. [30][31], During World War I, Bakelite was used widely, particularly in electrical systems. [19][20] The creation of marbled phenolic resins may also be attributable to the Catalin company. At first, Bakelite came only in dark colors because the wood shavings and asbestos fibers used to strengthen it showed up in the plastic if lighter colors were used. [18] It was demolished in 1998. 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 characteristics of Bakelite made it particularly suitable as a molding compound, an adhesive or binding agent, a varnish, and a protective coating. It is known as one of the first synthetic plastics, derived from methanol and coal tar. In 1907, Baekeland was seeking a more durable replacement for shellac and hard rubber. The range of colors available included "black, brown, red, yellow, green, gray, blue, and blends of two or more of these". By heating it under pressure, at about 150 °C (300 °F), Baekeland was able to suppress the foaming that would otherwise occur. Bakelite is still commonly used for dominoes, mah-jongg tiles, checkers, and chess pieces. It begins with heating of phenol and formaldehyde in the presence of a catalyst such as hydrochloric acid, zinc chloride, or the base ammonia. It is also resistant to electricity, and prized for its low conductivity.
