Koppers

Koppers is a leading integrated global provider of treated wood products, wood treatment chemicals, and carbon compounds. The company's Performance Chemicals segment is a global leader in the development of copper-based wood preservatives and fire retardants used in residential and industrial applications. Koppers also produces coal tar distillates, which serve as active ingredients in over-the-counter pharmaceutical products for skin conditions such as psoriasis and seborrheic dermatitis. While primarily an industrial chemical company serving the railroad, utility, and construction markets, its specialized chemical production provides a niche link to the healthcare and personal care sectors. Headquartered in Pittsburgh, Pennsylvania, Koppers operates a global manufacturing and distribution network.
