Braskem controls the three largest petrochemical complexes in Brazil, located in the cities of Camaçari, Bahia, Mauá, São Paulo and Triunfo, Rio Grande do Sul. Besides these three petrochemical complexes, Braskem also controls a complex in Duque de Caxias, Rio de Janeiro, which is based on gas rather than naphtha. Its basic petrochemical units account for the supply of ethylene and propylene to the company's nearby polymer units. The company also produces other chemical products such as benzene, butadiene, toluene, xylene and isoprene. These compounds are mostly sold to other chemical companies based within the same complexes, such as Innova S.A., Elekeiroz and Dow Chemical.
