Pyromellitis Dianhydride Hamwe na CAS 89-32-7
Dianhydride ya pyromellitike (mu magambo ahinnye yiswe PMDA), ikoreshwa cyane cyane muguhuza polyimide, kubera ko polyimide ifite imbaraga zidasanzwe zo kurwanya ubushyuhe bukabije, aside na alkali irwanya, nziza cyane Kubera imiterere yubukanishi, imiterere yamashanyarazi hamwe nuburinganire buringaniye, irakwira hose ikoreshwa mu buhanga buhanitse nk'indege, ikirere, icyogajuru, ingufu za atome, bifite ibisabwa bikomeye ku bintu bifatika.

Pyromellitis dianhydride (PMDA) ni ibikoresho byingenzi mu nganda ngengabihe, hamwe n’ibikoresho fatizo bigamije iterambere ry’ibikoresho bishya bya shimi n’ibicuruzwa byiza byongerewe agaciro. Ikoreshwa cyane cyane mugukora monomers ya polyimide, kandi irashobora no gukoreshwa nkumuti ukiza wa epoxy resin hamwe nu muti uhuza imiti ya polyester, ikoreshwa mugukora irangi ryubururu bwa phthalocyanine nibindi bikomokaho, nibindi, kandi bifite uburyo butandukanye bwo gukoresha. Pyromellitis dianhydride, izwi kandi nka homoanhydride, ifite imiterere yihariye ya molekile kandi irashobora gukoreshwa mugukora ibikoresho birwanya ubushyuhe, insimburangingo y’amashanyarazi hamwe n’imiti irwanya imiti, muri byo hakoreshwa cyane ni nka monolayeri ya polyimide. Ihujwe na diamine ya aromatic kugirango ibone plastiki ya polyimide, ariko ubuziranenge bwa pyromellitis dianhydride ni ndende cyane, bugomba kuba burenga 99%.
