Overview
Celanese is an American technology and specialty materials company headquartered in Irving, Texas. Its modern business combines large-scale chemical production with engineered polymers, cellulose acetate products, food ingredients, emulsions, and other specialty materials. The company serves automotive, electronics, medical, construction, coatings, adhesives, packaging, textiles, food and beverage, and tobacco-related markets. Its principal activities are organized around acetyl intermediates, advanced engineered materials, consumer specialties, and industrial specialties, with additional development of fuel-related technologies. The business traces its origins to the American Cellulose & Chemical Manufacturing Company, founded in New York City in 1918 by Swiss chemist Camille Dreyfus. The original purpose was to develop cellulose-based materials and yarns as alternatives to silk and other imported fibers. During World War I, the company established a plant in Cumberland, Maryland, an inland location selected for access to water, coal, rail transportation, and protection from possible attacks on coastal industrial sites. Commercial production at the facility began in 1924. In 1925, the company introduced the Celanese name, combining “cellulose” with “ease” to emphasize the easy-care properties of acetate fabrics. The corporate name became Celanese Corporation of America in 1927. Following World War II, Celanese expanded its international manufacturing and product portfolio. It began producing acetate fiber in Mexico in 1947 and by the late 1950s operated a substantial network of plants, research facilities, and product groups. The company used architecture and design, including the 1959 Celanese House in New Canaan, Connecticut, to demonstrate applications for its synthetic materials. Over subsequent decades, it moved beyond fibers into industrial chemicals, high-performance polymers, protective-apparel materials, and other specialty products. The company underwent major ownership and structural changes. In 1982, it acquired selected operations of Imperial Chemical Industries, and in 1983 it built a polybenzimidazole plant in South Carolina. In 1986, it spun off its pharmaceutical business as Celgene. In 1987, Hoechst AG acquired Celanese Corporation, forming Hoechst Celanese. In the late 1990s, Hoechst reorganized much of its industrial-chemical portfolio into Celanese AG, which was later spun off as a publicly traded German company. In 2004, Blackstone acquired Celanese AG, restored the Celanese Corporation name, and carried out operational streamlining and acquisitions. In January 2005, Celanese completed an initial public offering on the New York Stock Exchange under the ticker CE. Blackstone sold its remaining investment by 2007. Celanese is particularly prominent in acetyl chemistry. It has been described as the world’s leading producer of acetic acid and the largest producer of vinyl acetate monomer, materials used in adhesives, coatings, construction products, polymers, and numerous chemical processes. The company operates production facilities and research centers in multiple countries, including large acetic acid plants in Texas, Singapore, and China. Its advanced engineered materials business supplies polymers for demanding applications such as fuel systems, emissions control, electronics, safety equipment, medical devices, fluid handling, and industrial conveying. The company has also reshaped its portfolio through divestitures and acquisitions. Its engineering-polymer capabilities were expanded through the 2016 acquisition of Italy’s SO.F.TER Group. In 2020, Celanese sold its 45 percent stake in Polyplastics to Daicel, which already held the remaining 55 percent. Other portfolio actions include the 2009 sale of its polyvinyl alcohol business to Sekisui Chemical. Celanese promotes TCX Technology, a process for producing ethanol from hydrocarbon feedstocks.
History
Celanese began in 1918 as the American Cellulose & Chemical Manufacturing Company, also known as Amcelle. Swiss chemist Camille Dreyfus founded the company in New York City to develop cellulose-based materials and textile fibers. A manufacturing site in Cumberland, Maryland, originated during World War I. Its inland position offered access to the Potomac River, coal, rail connections, and relative protection from attacks. Production was delayed, but the plant began commercial operations on Christmas Day in 1924, making cellulose acetate fabrics and yarns intended to provide an alternative to silk. The Celanese name appeared in 1925. It was formed from “cellulose” and “ease,” reflecting the company’s promotion of acetate textiles as easier to clean and maintain. The business formally became Celanese Corporation of America in 1927. After the war, the company expanded internationally and entered Mexico with an acetate-fiber plant near Ocotlán in 1947. By 1958, it had developed a broad domestic manufacturing and research network, with 13 plants, three research and development centers, approximately 30 product groups, and about 13,000 employees. Celanese used product design and architecture to demonstrate the potential of synthetic materials. In 1959, it commissioned architect Edward Durell Stone to create the Celanese House, a model residence in New Canaan, Connecticut. The project showcased contemporary applications of company materials and formed part of a wider effort to connect chemical innovation with consumer design. The company diversified substantially during the 1980s. In 1982, it acquired selected operations of Imperial Chemical Industries, including the Fiber Industries plant in Salisbury, North Carolina. In 1983, it constructed a polybenzimidazole facility in Rock Hill, South Carolina. Polybenzimidazole was used in high-performance protective apparel, including firefighters’ equipment and astronaut suits. In 1986, Celanese separated its pharmaceutical business as Celgene. Hoechst AG acquired Celanese Corporation in 1987 and combined it with American Hoechst to form Hoechst Celanese Corporation. The following decade brought further restructuring. Hoechst Celanese sought to consolidate and rationalize its international operations, while its Trevira division was sold in 1998 to a consortium involving KoSa, Koch Industries, and Mexican partners. Hoechst also organized much of its industrial-chemical activity into Celanese AG. In 1999, Celanese AG was spun off as a publicly traded German company, listed in Frankfurt and New York, in a restructuring connected to Hoechst’s broader combination with Rhône-Poulenc. Blackstone announced a takeover offer in December 2003 after pursuing the company for approximately two years. Shareholders approved the transaction in June 2004, and the acquisition was completed later that year. The company was delisted from the New York Stock Exchange, renamed Celanese Corporation, and subjected to operational streamlining and portfolio changes under private-equity ownership. Celanese returned to the public market through a January 2005 initial public offering under the symbol CE. Blackstone sold its remaining shares by 2007. The modern company has focused on acetyl intermediates, engineered materials, consumer specialties, and industrial specialties. Its acetyl business produces acetic acid, acetic anhydride, vinyl acetate monomer, and related chemicals used in coatings, adhesives, construction materials, and polymer production. Advanced engineered materials supplies plastics and compounds for automotive, electronics, telecommunications, medical, safety, emissions, and fluid-management applications. Consumer specialties includes cellulose acetate, food preservatives, high-intensity sweeteners, and cellulose acetate film. Industrial specialties converts acetyl feedstocks into emulsions and polymers for paper, construction, textiles, coatings, and adhesives. Celanese expanded its engineering-materials portfolio with the 2016 acquisition of SO.F.TER Group in Italy. It sold its polyvinyl alcohol business to Sekisui Chemical in 2009 and divested its 45 percent interest in Polyplastics to Daicel in 2020, leaving Daicel with full ownership. The company also developed TCX Technology, launched in 2010, to produce ethanol from hydrocarbon feedstocks. Its historical record includes significant litigation over polybutylene plumbing systems and a later environmental class action concerning alleged contamination near a former South Carolina facility.
