Mu myaka ya vuba aha, bitewe n’uko ubushobozi bw’umusaruro bukomeje kwiyongera mu nganda za polypropylene zo mu gihugu, umusaruro wa polypropylene wakomeje kwiyongera umwaka ku wundi. Bitewe n’ubwiyongere bw’ibiciro by’imodoka, ibikoresho byo mu rugo, amashanyarazi, na pallet, umusaruro wa polypropylene ya copolymer idakira ingaruka urimo kwiyongera cyane. Umusaruro witezwe wa copolymer idakira ingaruka muri 2023 ni toni miliyoni 7.5355, ubwiyongere bwa 16.52% ugereranije n’umwaka ushize (toni miliyoni 6.467). By’umwihariko, mu bijyanye no kugabanya ibice, umusaruro wa copolymer zidakira umwuka ni munini, aho umusaruro witezweho ungana na toni miliyoni 4.17 muri 2023, ungana na 55% by’umusaruro wose wa copolymer zidakira ingaruka. Igipimo cy’umusaruro wa copolymer zikira umwuka uciriritse n’izikira ingaruka gikomeje kwiyongera, kikagera kuri toni miliyoni 1.25 na 2.12 muri 2023, ungana na 17% na 28% by’umusaruro wose.
Ku bijyanye n'igiciro, mu 2023, icyerekezo rusange cya polypropylene ya copolymer idakora ingaruka cyatangiye kugabanuka hanyuma kikazamuka, hagakurikiraho kugabanuka guke. Itandukaniro ry'ibiciro hagati ya copolymerization na threading mu mwaka wose riri hagati ya yuan 100-650/toni. Mu gihembwe cya kabiri, bitewe no kurekura buhoro buhoro umusaruro uva mu nganda nshya, hamwe n'igihe cyo gukenera, ibigo by'ibicuruzwa bya terminal byari bifite komande nke kandi icyizere cy'amasoko muri rusange cyari gike, bituma isoko rigabanuka muri rusange. Bitewe n'ubwiyongere bunini bw'ibicuruzwa bya homopolymer byatewe n'igikoresho gishya, ipiganwa ry'ibiciro riri hejuru cyane, kandi igabanuka ry'ibiciro bisanzwe bya threading ririyongera. Mu buryo bufatika, copolymerization idakora ingaruka yagaragaje ubudahangarwa bukomeye bwo kugabanuka, aho itandukaniro ry'ibiciro hagati ya copolymerization na threading ryazamutse rigera kuri yuan 650/toni. Mu gihembwe cya gatatu, hamwe n'inkunga ihoraho ya politiki n'inkunga ikomeye y'ibiciro, ibintu byinshi byiza byatumye ibiciro bya PP bisubira inyuma. Uko itangwa rya copolymer zirwanya impanuka ryiyongeraga, izamuka ry'ibiciro by'ibicuruzwa bya copolymer ryagabanutse gato, kandi itandukaniro ry'ibiciro byo gushushanya copolymer ryasubiye ku rugero rusanzwe.
Igipimo nyamukuru cya pulasitiki ikoreshwa mu modoka ni PP, hagakurikiraho ibindi bikoresho bya pulasitiki nka ABS na PE. Nk’uko ishami ry’inganda rishinzwe inganda z’imodoka ribivuga, ikoreshwa rya pulasitiki kuri buri sedan mu Bushinwa ni hagati ya 50-60kg, amakamyo akomeye ashobora kugera kuri 80kg, naho ikoreshwa rya pulasitiki kuri sedan iciriritse n’iy’igiciro kinini mu Bushinwa ni hagati ya 100-130kg. Ikoreshwa ry’imodoka ryabaye igice cy’ingenzi cya polypropylene ya copolymer idakora neza, kandi mu myaka ibiri ishize, umusaruro w’imodoka wakomeje kwiyongera, cyane cyane hamwe n’ubwiyongere bugaragara bw’imodoka nshya zikoresha ingufu. Kuva muri Mutarama kugeza Ukwakira 2023, umusaruro n’igurishwa ry’imodoka byageze kuri miliyoni 24.016 na miliyoni 23.967, ubwiyongere bwa 8% na 9.1% buri mwaka. Mu gihe kizaza, hamwe no kwiyongera guhoraho no kugaragara kw’ingaruka za politiki z’iterambere rihamye ry’ubukungu mu gihugu, hamwe no gukomeza inkunga yo kugura imodoka zo mu gihugu, ibikorwa byo kwamamaza n’izindi ngamba, biteganijwe ko inganda z’imodoka zizakora neza. Biteganijwe ko ikoreshwa rya copolymers zirwanya ingaruka mu nganda z'imodoka naryo rizaba rinini mu gihe kizaza.
