Chemische Industrie Uithoorn (Cindu, later Cindu Chemicals) was a chemical company in Uithoorn, Netherlands specialising in processing from coal tar. The company was founded in 1922 as Teerbedrijf Uithoorn (TEBU), and operated under a number of company names. It was acquired by Koppers in 2010 and renamed Koppers Netherlands. A subsidiary producing polymers from tar derived chemicals was formed in 1960 as Neville Cindu Chemie (later Nevcin Polymers) and operated from the same site in Uithoorn. A reactor at the factory exploded in 1992, causing three deaths and several injuries.
