Dianhydride ya Pyromellitic ifite CAS 89-32-7
Dianhydride ya pyromellitic (ihinnye nka PMDA), ikoreshwa cyane mu gukora polyimide, kuko polyimide ifite ubushobozi bwo kurwanya ubushyuhe bwinshi, irwanya aside na alkali, ikaba nziza cyane Kubera imiterere yayo ya mekanike, imiterere y'amashanyarazi n'ubudahangarwa bwayo mu bipimo, ikoreshwa cyane mu ikoranabuhanga rigezweho nko mu ndege, mu kirere, mu by'ikoranabuhanga riciriritse no mu ngufu za atome, zifite ibisabwa bikomeye ku miterere y'ibikoresho.

Dianhydride ya Pyromellitic (PMDA) ni igikoresho cy'ingenzi mu nganda zikora imyuka ikomoka ku bimera, ndetse n'ibikoresho by'ibanze mu guteza imbere ibikoresho bishya bya shimi n'ibicuruzwa by'imiti byiza byongerewe agaciro. Ikoreshwa cyane cyane mu gukora monomeri za polyimide, kandi ishobora no gukoreshwa nk'umuti uvura epoxy resin n'umuti uhuza polyester resin, ikoreshwa mu gukora irangi ry'ubururu rya phthalocyanine n'ibindi bintu by'ingenzi, nibindi, kandi ifite uburyo bwinshi bwo kuyikoresha. Dianhydride ya Pyromellitic, izwi kandi nka homoanhydride, ifite imiterere yihariye ya molekile kandi ishobora gukoreshwa mu gukora ibikoresho bifite ubushyuhe burambye, amashanyarazi akingira kandi birwanya imiti, muri byo ikoreshwa cyane ni nk'urupapuro rumwe rwa polyimide. Ikorwa na diamine ihumura neza kugira ngo ibone plastiki ya polyimide, ariko ubuziranenge bwa dianhydride ya pyromellitic buri hejuru cyane, bugomba kuba burenga 99%.
