Ko te dianhydride pyromellitic (e whakarāpopototia ana ko PMDA), e whakamahia ana mō te hanga polyimide, nā te mea he tino pai te ātete wera nui o te polyimide, te ātete waikawa me te kawakore, he tino pai. Nā ōna āhuatanga miihini, āhuatanga hiko me te pumau o te taha, e whakamahia whānuitia ana i roto i ngā mara hangarau teitei pēnei i te rererangi, te aerospace, te microelectronics me te pūngao ngota, he tino whakaritenga mō ngā āhuatanga rauemi.
| Taonga | Paerewa |
| Āhua | Ngā tioata mā |
| Mpūwāhi whakatītaha | 286℃-288℃ |
| Te tautohetohe waikawa kore utu | ≤0.5wt% |

He rauemi mata nui te Pyromellitic dianhydride (PMDA) i roto i te umanga hanga matū waro, me te rauemi mata taketake hoki mō te whakawhanake i ngā rauemi matū hou me ngā hua matū pai kua tāpirihia he uara nui. Ko te nuinga o te whakamahinga he mea hanga mō te hanga monomers polyimide, ā, ka taea hoki te whakamahi hei kaihoko whakaora mō te kapia epoxy me te kaihoko hononga-whiti mō te kapia polyester, e whakamahia ana i roto i te hanga tae kikorangi phthalocyanine me ētahi atu mea nui, ā, he whānuitia ngā whakamahinga. Ko te Pyromellitic dianhydride, e mōhiotia ana ko te homoanhydride, he hanganga ngota motuhake, ā, ka taea te whakamahi hei hanga rauemi ātete wera, ātete hiko me te ātete matū, ko te whakamahinga nui ko te paparanga kotahi o te polyimide. Ka hangaia ki te diamine kakara hei whiwhi kirihou polyimide, engari he tino teitei te parakore o te pyromellitic dianhydride, me neke atu i te 99%.
