Isticmaalka
Dioctyl terephthalate (DOTP) waa balaastig ugu weyn oo leh waxqabad aad u fiican oo loogu talagalay balaastikada polyvinyl chloride (PVC). Marka la barbardhigo phthalate diisooctyl (DOP) ee caadiga ah ee la isticmaalo, waxay leedahay faa'iidooyinka iska caabbinta kulaylka, iska caabbinta qabowga, isbeddelka adag, ka-hortagga soo saarista, jilicsanaanta, iyo sifooyinka dahaarka korantada ee wanaagsan. Waxay muujinaysaa cimri dherer aad u fiican, iska caabbinta biyaha saabuunta iyo jilicsanaanta heerkulka hooseeya ee alaabada. Sababtoo ah isbeddelkeeda hooseeya, isticmaalka DOTP wuxuu si buuxda u dabooli karaa shuruudaha heerka iska caabbinta heerkulka ee fiilooyinka iyo fiilooyinka, waxaana si ballaaran loogu isticmaali karaa agabka fiilooyinka ee u adkaysta 70.° C (Heerka IEC ee Guddiga Caalamiga ah ee Elektroteknolojiyadda) iyo alaabada kale ee jilicsan ee PVC.
Marka laga soo tago tiro badan oo balaastig ah oo loogu talagalay agabka fiilooyinka iyo PVC, DOTP waxaa sidoo kale loo isticmaali karaa soo saarista filimada maqaarka ee macmalka ah. Intaa waxaa dheer, DOTP waxay leedahay milmi heer sare ah waxaana sidoo kale loo isticmaali karaa balaastig ahaan waxyaabaha laga sameeyay acrylonitrile, polyethylene, alcohol butyraldehyde, cinjirka nitrile, nitrocellulose, iwm. Waxa kale oo loo isticmaali karaa balaastig ahaan caagga isku-dhafka ah, waxyaabaha lagu daro dahaarka, saliidaha qalabka saxda ah, waxyaabaha lagu daro saliidaha, iyo jilciyeyaasha warqadda.
