Isicelo

4,4′-oxydiphthalic anhydrideisetshenziselwe ukulungisa i-polyimide material.

Izimo zokugcina

Gcina isitsha sivaliwe futhi sigcinwe endaweni epholile neyomile, futhi uqinisekise ukuthi kunomoya omuhle noma idivayisi yokukhipha umoya endaweni yokusebenza.

Ukuzinza

Uma isetshenziswe futhi igcinwe ngokuhambisana nemininingwane, ngeke ibole. Akukho ukusabela okuyingozi okwaziwayo. Gwema ama-oxide.
