Isicelo

I-Isophthalic acid isetshenziswa kakhulu ekukhiqizeni i-polyester resin engagcwele, umunwe wesihlahla se-PET copolymer kanye ne-alkyd resin.Ngaphezu kwalokho, i-isophthalic acid njengempahla eluhlaza ingasetshenziswa futhi ukulungisa i-polyisophthalic acid allyl ester (DAIP) resin, esetshenziswa kabanzi ekwenzeni izingxenye eziqinile neziyinkimbinkimbi zokushisa ezisezingeni eliphezulu kanye nama-laminate afakiwe.Ukulungiswa kwe-diethyl isophthalate (DEIP) njenge-solvent ekhethekile ye-Chemicalbook ekukhiqizeni i-toluene diisocyanate;Ukulungiswa kwe-polybenzimidazole esetshenziswa njenge-adhesive ye-aluminium alloy, insimbi engagqwali nezinye izinto zensimbi, isakhiwo sezinyosi zensimbi, ifilimu ye-polyimide, i-silicon wafer nezinye izinto;I-Diisooctyl isophthalate, i-plasticizer ewuketshezi kawoyela engenambala ehambisana kahle ne-PVC, i-nitrocellulose, i-polystyrene namanye ama-resin, yalungiswa.
