Ashitada isophthalic waxaa inta badan loo isticmaalaa soo saarida xabagta polyesterka ee aan dheregsanayn, farta geedka copolymer PET iyo resin alkyd. Intaa waxaa dheer, isophthalic acid sida walxo ceeriin ah ayaa sidoo kale loo isticmaali karaa si loogu diyaariyo polyisophthalic acid allyl ester (DAIP), kaas oo si ballaaran loogu isticmaalo soo saarista saxnaanta iyo qaybo kakan oo heerkul sare ah iyo laminates-la'aanta. Diyaarinta diethyl isophthalate (DEIP) sida dareere gaar ah oo kiimiko ah ee soo saarista toluene diisocyanate; Diyaarinta polybenzimidazole oo loo isticmaalo sida xabagta aluminiumka aluminiumka, birta aan lahayn iyo walxaha kale ee birta ah, qaab dhismeedka malabka birta, filimka polyimide, wafer silicon iyo qalab kale; Diisooctyl isophthalate, caagadeeyaha dareeraha ah ee saliida aan midab lahayn oo leh ku habboonaanta PVC, nitrocellulose, polystyrene iyo resins kale, ayaa la diyaariyey.
