Bakelite, trademark of phenol-formaldehyde resin, trademarked synthetic resin invented in 1907 by Belgian-born American chemist Leo Hendrik Baekeland. Also, because of the smooth polished surface that resulted, Bakelite objects required less finishing. [7]:53 Paper, cotton fabrics, synthetic fabrics, glass fabrics and unwoven fabrics are all possible materials used in lamination. [61], By the late 1940s, newer materials were superseding Bakelite in many areas. He formed the General Bakelite Company as a U.S. company to manufacture and market his new industrial material. 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 range of colors available included "black, brown, red, yellow, green, gray, blue, and blends of two or more of these". Plastics formed from other formulas can be reshaped after reheating or will burst into flame if reheated. [7]:107 By the 1930s, Bakelite was used for game pieces like chessmen, poker chips,[45] dominoes[46] and mahjong sets. 96. "Sometimes I sing and dance in my underwear, but that don't make me Madonna!"

Phenolic sheet is a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with synthetic resin. This variety includes clear material, for jewelry, smokers' articles, etc. Notes:Similar to E. German 30rd Bakelite, but generally darker in color with more pronounced streaking/mottling. [4], Baekeland then began experimenting on strengthening wood by impregnating it with a synthetic resin, rather than coating it. [26] When rubbed or burnt, Bakelite has a distinctive, acrid, sickly-sweet or fishy odor. For thousands of years, humans used stone to fashion tools. In addition to the original Bakelite material, these companies eventually made a wide range of other products, many of which were marketed under the brand name "Bakelite plastics". However, the high temperatures required to create this tends to cause violent foaming of the mixture when done at standard atmospheric pressure, which results in the cooled material being porous and breakable. Bakelite stock is still manufactured and produced in sheet, rod and tube form for industrial applications in the electronics, power generation and aerospace industries, and under a variety of commercial brand names. By 1930, designer Paul T. Frankl considered Bakelite a "Materia Nova", "expressive of our own age". 2)It does not become soft on getting heated.

In 1907 the invention of Bakelite brought about a revolution in materials by introducing truly synthetic plastic resins into world commerce. Making Bakelite is a multi-stage process. 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. All Hello, Sign in. Once Baekeland's heat and pressure patents expired in 1927, Bakelite Corporation faced serious competition from other companies. [41] :27–29 Designers such as Elsa Schiaparelli used it for jewelry and also for specially designed dress buttons. [55][56] In 1943, the thermosetting phenolic resin was even considered for the manufacture of coins, due to a shortage of traditional material. It is also resistant to electricity, and prized for its low conductivity. Bakelite is actually a real-life substance, however, real bakelite doesn't have the properties that "bakelite" does in the series. which means many units (parts). By heating it under pressure, at about 150 °C (300 °F), Baekeland was able to suppress the foaming that would otherwise occur. The AKM and some early AK-74 rifles are frequently mistakenly identified as using Bakelite, but most were made with AG-S4. There are two systems of nomenclature of aldehydes and ketones. It can be quickly molded. Bakelite or polyoxybenzylmethylenglycolanhydride was the first plastic made from synthetic components. Notes. Some of these magazines were painted black, allegedly to help differentiate between the Bakelite 5.45 and 7.62 mags when both were simultaneously in widespread use. "[14]: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".[17]. [7], Baekeland filed a substantial number of patents in the area. Bakelite:It is a very hard and tough plastic.It is a poor conductor of heat and electricity. [9] He announced his invention at a meeting of the American Chemical Society on February 5, 1909. [8] Producing hard, compact, insoluble and infusible condensation products of phenols and formaldehyde marked the beginning of the modern plastics industry. [51][52] By 1935, it was used in solid-body electric guitars. Bakelite was particularly suitable for the emerging electrical and automobile industries because of its extraordinarily high resistance to electricity, heat, and chemical action. 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. Genmitsu 3018 Pro Assembly Notes.
