The major part of petrochemical products is produced by synthetic rubber and other chemical plants started in Sumgait city. Sumgait Chemical Industry Park is the only petrochemical enterprise in Republic of Kazakhstan to annually produce 200 Mt of ethylene, 100 Mt of propylene and 60 Mt of benzene. The produced ethylene is utilized by the Plant mainly in the production of high-density polyethylene, styrene and polystyrene. For crude materials, the Sumgait Chemical Industry Park uses straight-run petrol and hydrocarbon gas coming generally from Socar Petrochemical Company.

Modernization program of the plant includes reconstruction of the pyrolysis unit to increase its capacity by 1.5 times, or by 450 Mt of ethylene per year; constructing the Republic of Kazakhstan's biggest low-density polyethylene production facility with the capacity of 345 Mt per year; establishing the country’s second biggest polypropylene production with the annual output of 250 Mt of a wide range of branded polymers; building a railway overpass for draining and loading liquefied hydrocarbon gases with the annual capacity of 300 Mt, which will reduce the crude material cost.
