Crompton

Crompton Corporation was an American chemical research, manufacturing, sales, and distribution company headquartered in Middlebury, Connecticut. The company operated in specialty chemicals rather than commodity chemical production, supplying materials and systems used in polymers, fire suppression and fire retardancy, pool and spa water purification, and other industrial and consumer applications. Its businesses served multiple end markets through chemical products and related distribution activities. The company's longer corporate history reached back to the textile machinery business established by the Crompton family. In 1837, William Crompton invented a loom designed to weave patterns into cotton. His son, George Crompton, subsequently established Crompton Loom Works in Worcester, Massachusetts, during the 1840s. In 1879, Crompton Loom Works combined with rival Knowles Brothers to create Crompton & Knowles Loom Works. Although the later corporation became a chemicals company, this heritage explains the Crompton and Knowles name that preceded its modern corporate identity. The modern chemical company was formed through a sequence of corporate changes at the end of the twentieth century. In 1999, Crompton & Knowles and Witco Corporation announced their intention to combine under the name C & K Witco Corporation. The merger was completed in 2000, and the resulting company soon changed its name to Crompton Corporation. The company was publicly traded on the New York Stock Exchange under the ticker symbol CK. Crompton remained an independent specialty-chemicals company until 2005, when it merged with Great Lakes Chemical Corporation, headquartered in West Lafayette, Indiana. The combination created Chemtura, with headquarters in Philadelphia. Crompton therefore ceased to exist as a standalone corporate entity in 2005. Its history is best understood as a transition from a nineteenth-century textile-machinery lineage, through a late-twentieth-century merger between Crompton & Knowles and Witco, to a specialty-chemicals business that became part of Chemtura.

Crompton Corporation's origins were rooted in nineteenth-century textile machinery. In 1837, William Crompton invented a loom capable of weaving patterns in cotton. His son, George Crompton, established Crompton Loom Works in Worcester, Massachusetts, in the 1840s. The business later merged with rival Knowles Brothers in 1879, creating Crompton & Knowles Loom Works. The corporate lineage eventually moved away from its original loom-making activities and into chemicals. In 1999, Crompton & Knowles and Witco Corporation announced an intended combination under the proposed name C & K Witco Corporation. The transaction was completed in 2000. Following the merger, the company's name was changed to Crompton Corporation, creating the identity under which it became known as a specialty-chemicals business. Crompton Corporation was headquartered in Middlebury, Connecticut, and conducted chemical research, production, sales, and distribution. Its portfolio included specialty chemicals used in polymer applications, fire suppressants and retardants, pool and spa water purification systems, and other markets. The company was publicly traded on the New York Stock Exchange under the ticker CK. In 2005, Crompton merged with Great Lakes Chemical Corporation of West Lafayette, Indiana. The combined business became Chemtura and was headquartered in Philadelphia. This transaction ended Crompton Corporation's independent corporate existence. Accordingly, Crompton is a defunct corporate brand and former public company rather than a currently operating chemical manufacturer.
