ʻO ka pyromellitic dianhydride (i hoʻopōkole ʻia e like me PMDA), ka mea i hoʻohana nui ʻia no ka synthesis o polyimide, no ka mea, he kūpaʻa wela kiʻekiʻe loa ka polyimide, ka waikawa a me ke kūpaʻa alkali, maikaʻi loa. Ma muli o kona mau waiwai mechanical, nā waiwai uila a me ke kūpaʻa dimensional, hoʻohana nui ʻia ia i nā kahua ʻenehana kiʻekiʻe e like me ka mokulele, aerospace, microelectronics a me ka ikehu atomika, nona nā koi koʻikoʻi no nā waiwai mea.

ʻO Pyromellitic dianhydride (PMDA) kahi mea maka koʻikoʻi i ka ʻoihana synthesis organik, a he mea maka kumu hoʻi no ka hoʻomohala ʻana i nā mea kemika hou a me nā huahana kemika maikaʻi i hoʻohui ʻia me ka waiwai kiʻekiʻe. Hoʻohana nui ʻia ia no ka hana ʻana o nā monomers polyimide, a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻōla no ka epoxy resin a me ka mea hoʻopili cross-linking no ka polyester resin, hoʻohana ʻia i ka hana ʻana o ka phthalocyanine blue dye a me kekahi mau derivatives koʻikoʻi, a he ākea ka hoʻohana ʻana. ʻO Pyromellitic dianhydride, i ʻike ʻia hoʻi ʻo homoanhydride, he ʻano molekala kūikawā a hiki ke hoʻohana ʻia e hana i nā mea me ke kūpaʻa wela, ka insulation uila a me ke kūpaʻa kemika, ʻo ia ka hoʻohana nui loa ma ke ʻano he monolayer o polyimide. Hoʻohui ʻia me ka diamine aromatic e loaʻa ai ka plastic polyimide, akā kiʻekiʻe loa ka maʻemaʻe o ka pyromellitic dianhydride, pono e ʻoi aku ma mua o 99%.
