The two compounds that I chose that I would like to learn more about are bakelite and polysulfone. Bakelite was developed in 1909 and it was one of the first plastics to be made from synthetic compounds. In its early days it was used in a wide variety of products from jewelry to telephone casings to electrical insulators. Today it is most commonly used as a substitute for porcelain and other ceramics and it is also used in game pieces such as dominos, chess pieces, and checkers. It is also manufactured and produced today in tube, sheet, and rod form for industrial applications in aerospace industries, electronics, and power generation.
Polysulfone was developed in 1965 and is important because it is a very tough and rigid thermoplastic. This means that it is able to maintain its properties from a temperature range of 150 degrees Fahrenheit to above 300 degrees Fahrenheit. Its ability to withstand such high temperatures make it a good flame retardant and today it is used in many areas including in waste water recovery and in the automobile and electric industries.
