Kwiminyaka eli-10 edlulileyo, i-polypropylene ibisandisa amandla ayo, apho i-3.05 yezigidi zeetoni zandiswa ngo-2016, yaphula uphawu lweetoni ezingama-20 ezigidi, kwaye amandla emveliso iyonke afikelele kwiitoni ezingama-20.56 ezigidi. Ngo-2021, amandla aya kwandiswa ngeetoni ezingama-3.05 ezigidi, kwaye amandla emveliso iyonke aya kufikelela kwiitoni ezingama-31.57 ezigidi. Ukwandiswa kuya kugxininiswa ngo-2022. I-Jinlianchuang ilindele ukwandisa amandla ukuya kwiitoni ezingama-7.45 ezigidi ngo-2022. Kwisiqingatha sokuqala sonyaka, iitoni ezili-1.9 lezigidi ziye zasetyenziswa kakuhle. Kwiminyaka elishumi edlulileyo, amandla emveliso ye-polypropylene ebesendleleni yokwandisa amandla. Ukususela ngo-2013 ukuya ku-2021, izinga lokukhula eliphakathi kwamandla emveliso ye-polypropylene yasekhaya yi-11.72%. Ukusukela ngo-Agasti 2022, amandla emveliso ye-polypropylene yasekhaya iyonke yi-33.97 yezigidi zeetoni. Kuyabonakala kulo mfanekiso ungentla ukuba kubekho iincopho ezimbini ezincinci zokwandiswa kwamandla kwiminyaka elishumi edlulileyo. Eyokuqala yayilizinga lokukhula eliphakathi le-15% ukusuka ngo-2013 ukuya ku-2016. Ukwandiswa kwamandla ngo-2014 yayiziitoni ezi-3.25 ezigidi, unyaka owawunokwandiswa kwamandla amakhulu. Iitoni ezi-3.05 ezigidi, zidlula uphawu lweetoni ezi-20 ezigidi, kunye nomthamo wemveliso iyonke weetoni ezi-20.56 ezigidi. Incopho yesibini yokwandiswa kwamandla iku-2019-2021, kunye nomlinganiselo wokukhula ophakathi we-12.63%. Ngo-2021, umthamo uya kwandiswa ngeetoni ezi-3.03 ezigidi, kunye nomthamo wemveliso iyonke weetoni ezi-31.57 ezigidi. Kwisiqingatha sokuqala sowama-2022, iitoni ezi-1.9 ezigidi zifakiwe kwimveliso, kwaye amashishini amatsha asasazwa eMpuma China, eMntla China naseMntla-mpuma China. IMpuma China yayinomthamo omtsha omkhulu weetoni ezi-1.2 ezigidi. Phakathi kwazo, iZhejiang Petrochemical inomthamo wemveliso iyonke weetoni ezingama-900,000. Okwangoku, iZhejiang Petrochemical inomthamo wemveliso iyonke weetoni ezili-1.8 lezigidi. Okwangoku yeyona mveliso inkulu ye-polypropylene. Ngokwemithombo yezinto ezisetyenzisiweyo, iDaqing Haiding yenziwe nge-PDH, iTianjin Bohua yenziwe nge-MTO, kwaye ezinye zenziwe ngeoyile, ezibalelwa kwi-79%.
