Carbon Materials and Chemicals
Koppers carbon materials and chemicals are essential to the production of aluminum, steel, plastics, resins, treated wood, and rubber products. In addition, the carbon materials and chemicals also increase the durability of many products including railroad ties, utility and transmission poles, and marine pilings.
As a leading distiller of coal tar, a by-product of the transformation of coal into coke, Koppers produces carbon pitch, refined tar, creosote, carbon black feedstock and chemical oils. The chemical oils resulting from distillation are used to produce naphthalene and phthalic anhydride (PAA).
