DOTP plasticizer yog ib hom plasticizer, cov khoom no yuav luag tsis muaj xim tsis muaj viscosity kua. Cov viscosity yog 63mPa.s (25 ° C), 5mPa.s (100 ° C), 410mPa.s (0 ° C). Khov khov-taw tes -48 ℃. Kub taw tes yog 383 ℃ (0.1) MPa.s (0 ℃). Cov paib taw yog 399 ℃. Lub npe hauv lub npe: Dioctyl terephthalate.
Dioctyl terephthalate (DOTP) yog cov khoom yas zoo tshaj plaws rau cov yas ua polyvinyl chloride (PVC). Piv nrog rau cov khoom siv feem ntau diisooctyl phthalate (DOP), nws muaj qhov zoo ntawm kev tiv thaiv thaum tshav kub kub, tiv taus txias, nyuaj rau volatilize, tiv taus tawm, yooj thiab hluav taws xob rwb thaiv tsev, thiab qhia tau zoo tshaj plaws hauv cov khoom. Kev tiv thaiv ntawm soapy dej thiab kub yooj yim. Vim tias nws cov hluav taws xob tsis tshua muaj siab, kev siv DOTP tuaj yeem ua tau raws li qhov kub tsis kam tiv thaiv ntawm cov xov hlau thiab cov kab hluav taws xob, thiab tuaj yeem siv dav hauv 70 ° C-resistant cable khoom (IEC txuj ntawm International Electrotechnical Commission) thiab ntau lwm yam khoom muag PVC muag Cov. Ntxiv rau ntau cov plasticizers rau cov khoom siv cable thiab PVC, DOTP kuj tseem tuaj yeem siv rau kev tsim cov tawv ntoo cuav. Ntxiv rau, nws muaj qhov sib txawv zoo heev thiab tuaj yeem siv los ua cov yas rau acrylonitrile derivatives, polyvinyl butyral, nitrile roj hmab, nitrocellulose, thiab lwm yam. Nws tseem tuaj yeem siv ua cov yas rau cov hluavtaws roj hmab, pleev xim ntxiv, qhov ntsuas lub tshuab ua kom zoo, roj nplua nyeem ntxiv , thiab raws li ua kom tawv muag rau cov ntawv.
