Koppers is a global chemical and materials company based in Pittsburgh, Pennsylvania, United States in an art-deco 1920s skyscraper, the Koppers Tower.

Structure[edit]

The corporation is divided into two divisions: Carbon and Chemicals, and Railroad and Utility. The company specialises in manufacturing carbon chemicals from coal tar. The five main chemicals that are produced are coal pitch for steel and aluminum production, carbon black for rubber vulcanization, creosote for wood treatment, and naphthalene and phthalic anhydride for plastics and polyester. Kopper's coal tar pitches are essential to manufacturing carbon anodes for aluminum smelting. Koppers also has extensive operations making creosote treated wood products, especially railroad ties and switches. Utility poles, foundations, decking materials, and wooden panneling are also produced by the company.

History[edit]

In 1943, Koppers, at the US Government's behest, built a factory in Kobuta, Pennsylvania on the left bank of the Ohio River just downriver from Beaver, to manufacture styrene-butadiene monomer, a building block used to make a form of synthetic rubber for the World War II defense effort.

In 1951, at Port Arthur, Texas, the company built a plant to manufacture the chemical monomer ethylbenzene, using as raw materials ethylene from the nearby Gulf Oil refinery, and benzene, which was a byproduct of the company's coke ovens in Pennsylvania and which was shipped down to Texas by barge. The ethylbenzene produced there was then shipped by barge back up to the Kobuta plant where it was converted to styrene monomer, and then polymerized to make expandable polystyrene. In the early 1950s, the company purchased a license to manufacture polyethylene at its Port Arthur plant. These chemical operations later were the basis for forming a new corporate entity with Sinclair Oil Corporation to form the Sinclair-Koppers Company in 1965.

Beazer hostile takeover[edit]

In early 1988 Beazer, a British conglomerate run by one of the foremost corporate raiders of the 1980s, successfully launched a hostile takeover of Koppers for $1.81 billion ($3.8 billion today). The sale was completed on June 17, 1988.[1] A smaller, more streamlined domestic business unit of Koppers was bought back by local management in the early 2000s, and although much simpler than the once sprawling chemical and aggregate conglomerate of the early-to-mid 20th century, Koppers has once again become successful at its core businesses. In 2006 the new Beazer-free independent Koppers again went public [2].

Current business interests[edit]

Koppers operates facilities in the United States, Canada, United Kingdom, Denmark, Australia, China, South Africa. The coal tar processor Cindu Chemicals in the Netherlands was acquired in 2010.[1] Koppers sources coal tar from around the world for further processing by distillation into carbon chemicals. Its Monessen, Pennsylvania coke ovens have a combined annual capacity of over 360,000 tons. The company further operates coke ovens in Tangshan, People's Republic of China, and has co-located facilities near the operations of major steel makers.

Products[edit]

One of Koppers' leading products is coal tar. Asphalt sealants containing coal tar have high levels of benzo(a)pyrene and other toxic chemicals known collectively as polycyclic aromatic hydrocarbons, or PAHs.[2]
