    What is Pyromellitic Dianhydride With CAS 89-32-7?

    Dianhydride pyromellitica (abbreviata sicut PMDA), quae maxime adhibetur ad synthesim polyimidis, quia polyimida habet excellentem resistentiam caloris ultra-altalis, resistentiae acidi et alcali, optimae Propter proprietates mechanicas, proprietates electricas et stabilitatem dimensivam, late est. usus in campis summus technicis ut aviation, aerospace, microelectronica et energia atomica, quae stricte requisita in proprietatibus materialibus habent.

    Applicationem

    Pyromellitica dianhydrida (PMDA) est materia rudis momenti in synthesi organica industriae, necnon materia rudis fundamentalis ad novas chemicae materias evolutionis et magni pretii-additos productorum chemicorum. Maxime adhibetur ad monomeros polyimidos producendos, adhiberi potest etiam ut in curatione agentis pro epoxy resinae et transversalis coniunctionis agentis pro resina polyester, usus est in phthalocyanine tinctura hyacinthini et derivatis quibusdam momentis, etc. amplis usuum. Dianhydrida pyromellitica, etiam homoanhydrida nota, peculiarem habet structuram hypotheticam et adhiberi potest ad materias fabricandi resistentia caloris, resistentiae electricae et chemicae, inter quas maximus usus est monolayus polyimidis. Diamine aromatico componitur ut polyimidum plasticum obtineat, sed puritas dianhydride pyromelliticae est altissima, quae plus quam 99% debet esse.
