Maleic anhydride (MA) ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito kwambiri pamakampani opanga mankhwala. Ntchito zake zazikulu ndikuphatikiza kupanga ma unsaturated polyester resins (UPR), omwe ndi ofunikira popanga mapulasitiki opangidwa ndi fiberglass, zokutira, ndi zida zamagalimoto. Kuphatikiza apo, MA imagwira ntchito ngati kalambulabwalo wa 1,4-butanediol (BDO), yogwiritsidwa ntchito m'mapulasitiki osawonongeka, ndi zotumphukira zina monga fumaric acid ndi mankhwala aulimi36.
M'zaka zaposachedwa, msika wa MA wakumana ndi kusinthasintha kwakukulu. Mu 2024, mitengo idatsika ndi 17.05%, kuyambira pa 7,860 RMB/ton ndikutha pa 6,520 RMB/tani chifukwa chakuchulukira komanso kufunikira kofooka kuchokera kugawo lanyumba, ogula wamkulu wa UPR36. Komabe, kukwera kwamitengo kwakanthawi kunachitika panthawi yoyimitsa kupanga, monga kutseka mosayembekezeka kwa Wanhua Chemical mu Disembala 2024, komwe kunakweza mitengo mwachidule ndi 1,000 RMB/ton3.
Pofika mwezi wa Epulo 2025, mitengo ya MA imakhalabe yosasunthika, yokhala ndi mawu oyambira 6,100 mpaka 7,200 RMB/ton ku China, motengera zinthu monga ndalama zopangira (n-butane) komanso kusintha kofunikira kwapansi panthaka27. Msika ukuyembekezeka kukhala wopanikizika chifukwa chakuchulukirachulukira kopanga komanso kuchepa kwa kufunikira kochokera kumagulu azikhalidwe, ngakhale kukula kwazinthu zamagalimoto ndi zinthu zosawonongeka kungapereke chithandizo.
