Inombolo ye-Cas: 89-32-7 PMDA Pyromellitic dianhydride
Isingeniso esifushane
Imikhiqizo emsulwa ye-Pyromellitic dianhydride (PMDA) imhlophe noma iphuzi kancane. Uma ivezwa emoyeni omanzi izomunca ngokushesha umswakama ovela emoyeni bese ifakwa ku-Pyromellitic Acid. Incibilikiswa ku-dimethyl sulfoxide, i-dimethylformamide, i-acetone kanye nezinye izinyibilikisi eziphilayo, ezingancibiliki ku-ether, i-chloroform kanye ne-benzene. Isetshenziswa kakhulu njengezinto zokusetshenziswa ze-polyimide, kanye ne-ejenti yokuxhumanisa yokukhiqiza i-epoxy curing agent kanye nokuqothulwa kwe-polyester resin.
I-Pyromellitic acid (PMA), eyaziwa nangokuthi i-1,2,4,5-benzenetetracarboxylicacid, ikristalu elimhlophe kuya eliphuzi eliyimpuphu, isetshenziswa kakhulu ekwenziweni kwe-polyimide, i-octyl pyromelliate, njll., iyinto eyinhloko yokwenziwa kwe-matting curing agent.
