I-pyromellitic dianhydride (efinyeziweyo njenge-PMDA), esetyenziswa kakhulu ekuhlanganiseni i-polyimide, kuba i-polyimide inokumelana nobushushu obuphezulu kakhulu, ukumelana ne-asidi kunye ne-alkali, igqwesileyo Ngenxa yeempawu zayo zoomatshini, iimpawu zombane kunye nokuzinza kobukhulu, isetyenziswa kakhulu kwiindawo zobuchwepheshe obuphezulu ezifana neenqwelo moya, i-aerospace, i-microelectronics kunye namandla e-athomu, ezineemfuno ezingqongqo kwiimpawu zezinto.

I-Pyromellitic dianhydride (PMDA) sisixhobo esibalulekileyo kwishishini lokwenziwa kwezinto eziphilayo, kunye nesixhobo esisisiseko sokuphuhlisa izinto ezintsha zeekhemikhali kunye neemveliso zeekhemikhali ezintle ezongeziweyo ngexabiso eliphezulu. Isetyenziselwa kakhulu ukuvelisa ii-polyimide monomers, kwaye ingasetyenziswa njenge-ejenti yokuphilisa i-epoxy resin kunye ne-ejenti yokudibanisa i-polyester resin, esetyenziswa ekwenzeni idayi eluhlaza okwesibhakabhaka ye-phthalocyanine kunye nezinye izinto ezibalulekileyo, njl., kwaye inoluhlu olubanzi lokusetyenziswa. I-Pyromellitic dianhydride, eyaziwa ngokuba yi-homoanhydride, inesakhiwo esikhethekileyo se-molecular kwaye ingasetyenziselwa ukuvelisa izinto ezinokumelana nobushushu, ubushushu bombane kunye nokumelana neekhemikhali, phakathi kwazo eyona nto ibalulekileyo kukusetyenziswa njenge-monolayer ye-polyimide. Yenziwe nge-aromatic diamine ukuze ifumane iplastiki ye-polyimide, kodwa ubumsulwa be-pyromellitic dianhydride buphezulu kakhulu, ekufuneka bube ngaphezulu kwe-99%.
