Pyroroellitic dianhydride Cas89-32-7 / PMDA

Kugwiritsa ntchito

Pyroroellitic dianhydride ikhoza kugwiritsidwa ntchito popanga polymide utoto, womwe umagwiritsidwa ntchito ngati zida zophika zamagetsi zokutira zamagetsi. Amagwiritsidwanso ntchito kupanga epoxy zokutira zokongoletsera ndi ma pulasitiki, urea formaldehyde limakhazikika, zotupa za phthalocyuion, zoletsa zamagetsi, zojambula zamagetsi, etc.

Pyroroellitic dianhydridedand zotumphukira zimakhala ndi mapulogalamu osiyanasiyana. PMDA imagwiritsidwa ntchito ngati yoyipitsa ya epoxy slin, zopangira polysimira, ndipo wothandiziranitsa polyster abwerere ku horopolymer polythermer. Ili ndi zinthu zapamwamba kwambiri zapamwamba zomwe zimatha kugwiritsidwa ntchito mosalekeza kwa nthawi yayitali pa 2600c.

Zinthu zosaphika zomwe zimagwiritsidwa ntchito popanga mapikidwe otenthetsera a polymide ndi mafilimu osokoneza bongo; Itha kugwiritsidwa ntchito ngati chinthu chopangidwa ndi epoxy restin wothandizila wothandizila, okhazikika, ndi utoto, etc

Pyroroellitic dianhydride ikhoza kugwiritsidwa ntchito kupanga utoto wa polymide, kutentha kwa magetsi, ma pvc chotupa, ndi epoxy kuthira othandizira. Amagwiritsidwanso ntchito kupanga phthalocyunine utoto, etc
