Marun Petrochemical Co. was founded to bring into operation the seventh olefin on 21 January 1999. Operationalization of this plan with the production capacity of 1.1 million tons of polyethylene per year, setting us among the largest olefin producers, made it possible to convert C2+ (ethane), extracted from natural gas, into polymeric and chemical products through olefinic processes for the first time in the country.
