Bakelite is a material based on the Thermosetting Phenol Formaldehyde Resin , Polyoxybenzylmethylenglycolanhydride developed in 1907 – 1909 by Belgian-American Dr. Leo Baekeland . Formed by the reaction under heat and pressure of Phenol (a toxic, colourless crystalline solid) and Formaldehyde (a simple organic compound), generally with a Wood Flour filler, it was the first Plastic made from synthetic components. It was used for its electrically Nonconductive and heat-resistant properties in radio and telephone casings and electrical Insulators , and was also used in such diverse products as Kitchenware , Jewelery , pipe stems, and children's Toy s. In 1993 Bakelite was designated an ACS National Historical Chemical Landmark in recognition of its significance as the world's first synthetic plastic. {Link without Title} The Retro appeal of old Bakelite products and labor intensive manufacturing has made them quite collectable in recent years. The name Bakelite was originally a brand, trademark name, but it is currently considered a generic term for all phenolic resin products, though some phenolic products besides Bakelite are brand-named. . HISTORY Bakelite Corp. was formed in 1922 from General Bakelite Co., Condensite Corp. and Redmanol Co and subsequently merged into the Union Carbide And Carbon Corp oration in 1939. The American Catalin Corporation acquired the Bakelite formulas in 1927 and currently manufactures Bakelite cast resins. Bakelite Limited was formed in of Birmingham ; Mouldensite Limited of Darley Dale and Redmanol Chemical Products Company of London . Around 1928 a new factory opened in Tyseley , Birmingham. (The building was demolished in 1998 .) The company was later acquired by the Union Carbide And Carbon Corp oration. PHENOLICS Phenolics are little used in general consumer products today due to the cost and complexity of production and their brittle nature. An exception to the overall decline is the use in small precision-shaped components where their specific properties are required, such as moulded disc brake cylinders, saucepan handles, electrical plugs and switches and electrical iron parts. Today, Bakelite is manufactured and produced in the form of sheets, rods and tubes for hundreds of industrial applications in the electronics, power generation and aerospace industries,external living, and under a variety of commercial brand names. rotor]] Phenolic sheet is a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with synthetic resin. These layers of laminations are usually of cellulose paper, cotton fabrics, synthetic yarn fabrics, glass fabrics or unwoven fabrics. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the layers into a high-pressure thermosetting industrial laminated plastic. Bakelite Phenolic is produced in dozens of commercial grades and with various additives to meet diverse mechanical, electrical and thermal requirements. Some common types include:
