Description
[Dow Chemical] Trademark name for a series of thermosetting synthetic resins. The original Bakelite synthetic resin, composed of phenol formaldehyde, was discovered in 1907 by Dr. Leo Baekeland. It was a hard, thermosetting polymer that was resistant to water, oils, and solvents. The original Bakelite polymer was also a poor conductor of electricity and for the first 10 years of production, the company primarily made electrical insulators. From the 1920s - 40s, the dark-color, phenolic resin was used to make molded articles such as radio cabinets, telephone receivers, costume jewelry, dishes, and other household items. It was also used to laminate paper and fabric and to make imitation amber. Early Bakelite products were made in 5 colors (yellow, butterscotch, brown, green, and red) along with mixtures forming marbleized patterns. In 1927, the Bakelite patent expired and competing companies, such as Catalin, began selling colorful cast phenolic resin products. Soon Bakelite also introduced a colorful line of cast products called Bakelite cast resin. In 1939, the Bakelite Company merged with Union Carbide. During the early 40s, only black products were made because of the war. Since 1975, the term Bakelite has been used by Union Carbide (then Dow since 2001) for a series of molded polymers and adhesives that are composed of the following resins: Polyethylene (Bakelite DQDE), Polypropylene, Epoxy (Bakelite RD), phenolic, Polystyrene (Bakelite RMD), phenoxy, Polysulfone, ABS, acrylic, or vinyl (Bakelites QYNV, VYLF, EVA, AYAC, AYAA).
