By 2016, out of 4.7 million tons of poly-alefin (including polyethylene and polypropylene) produced in the Middle East, 23.4% is polypropylene. Mahshahr region with a production of 670 thousand tons, has been superrior from two regions of Assaluyeh and other regions with a total production of 435 thousand tons. 

Of the three Certification in this area, two are owned by Basell, one by BP and the other by A.B.B. One complex based in Assaluyeh is licensed under Basell and two complexes in other areas are licensed under Himont. The country's poly-alefin production capacity will reach about 10 million tons per year in the coming years. 

Meanwhile, the increase in Polypropylene was only 750,000 tons, which is also related to other regions. This means that Mahshahr and Assaluyeh will not have a share in the development of polypropylene. The share of this polymer in the total future capacity of poly-alephins produced in the country will decrease by 4.5% to 18.9%.
