Pampa Energía has three high complexity industrial plants for the production of a wide range of petrochemical products. Pampa is the only producer of monomer styrene, polystyrene and elastomers in Argentina, as well as the only integrated producer of goods ranging from oil and natural gas to plastics. As part of its efforts to integrate operations, it uses an important volume of its own benzene production to obtain styrene and, in turn, a substantial volume of styrene to manufacture polystyrene and SBR (‘Styrene Butadiene Rubber’).

The petrochemicals division is made up of:

Puerto General San Martín Integrated Petrochemical Complex (‘PGSM’)
  • Located in the Province of Santa Fe, in a strategic area for exports by sea, it was the first petrochemical complex set up in South America. It started operations in 1966 and, since then, it has supplied the domestic and international markets with subsequent expansion of its capacity.
  • The complex covers an area of 250 hectares and mainly produces styrene, ethylene, and ethylbenzene, raw materials for the production of polystyrene, used to manufacture plastics, rubber (for tires), aromatic solvents (used by other industries and for naphtha as well), and propellants (a key element for the production of deodorants).
  • The plant has an annual production capacity of 50 thousand tons of gases (LPG or liquefied petroleum gas, which is used as raw material, and propellants), 155 thousand tons of aromatics, 290 thousand tons of gasoline and refined products, 160 thousand tons of styrene, 55 thousand tons of SBR (‘Styrene Butadiene Rubber’), 180 thousand tons of ethyl benzene and 31 thousand tons of ethylene.
San Lorenzo Ethylene Plant
  • Located on the banks of the Paraná river, close to the PGSM petrochemical complex, connected through pipelines for the supply of ethylene as raw material for the production of ethyl benzene and styrene.
  • The plant feeds Puerto General San Martín‘s process with a production capacity of 19 thousand tons per year.
Polystyrene Plant
  • It is located in the city of Zárate, Province of Buenos Aires, on the Paraná de las Palmas river. It is part of one of the largest industrial complexes together with the city of Campana.
  • The plant produces polystyrene at two degrees: of general purpose (GPPS) and of high impact (HIPS), and bi-oriented polystyrene (BOPS, stretched in two directions) either transparent or colored, which is marketed in coils.
  • It has a production capacity of 65 thousand tons of polystyrene and 14 thousand tons of BOPS. Moreover, Pampa is the only integrated polystyrene producer at a national level.
