Iyo pyromellitic dianhydride (yakapfupikiswa sePMDA), iyo inonyanya kushandiswa pakugadzira polyimide, nekuti polyimide ine simba rekudzivirira kupisa kwakanyanya, inodzivirira asidhi uye alkali, yakanaka kwazvo. Nekuda kwehunhu hwayo hwemakanika, hunhu hwemagetsi uye kugadzikana kwehukuru, inoshandiswa zvakanyanya muminda yepamusoro-soro senge ndege, aerospace, microelectronics uye atomic energy, ine zvinodiwa zvakanyanya pahunhu hwezvinhu.

Pyromellitic dianhydride (PMDA) chinhu chakakosha muindasitiri yekugadzira organic synthesis, pamwe chete nezvinhu zvakakosha zvekugadzira zvinhu zvitsva zvemakemikari uye zvigadzirwa zvemakemikari akanaka zvakanyanya. Inonyanya kushandiswa kugadzira polyimide monomers, uye inogona zvakare kushandiswa seCuring agent ye epoxy resin uye cross-linking agent ye polyester resin, inoshandiswa mukugadzira phthalocyanine blue dye nezvimwe zvinhu zvakakosha, nezvimwewo, uye ine mashandisirwo akasiyana-siyana. Pyromellitic dianhydride, inozivikanwawo se homoanhydride, ine chimiro chakakosha chemorecular uye inogona kushandiswa kugadzira zvinhu zvine resistance yekupisa, insulation yemagetsi uye resistance yemakemikari, pakati pazvo kushandiswa kwakanyanya kuri se monolayer ye polyimide. Inogadzirwa ne aromatic diamine kuti iwane polyimide plastic, asi kuchena kwe pyromellitic dianhydride kwakanyanya, izvo zvinoda kupfuura 99%.
