Epoxidized cov roj taum yog ua los ntawm cov roj taum thiab hydrogen peroxide ua cov khoom siv tseem ceeb, siv cov txheej txheem ntau lawm thiab cov mis. Ua raws li cov cai ntawm US FDA cov qauv, roj epoxy kua roj muaj cov yam ntxwv ntawm tsis muaj ntxhiab tsw, tsis muaj kuab lom, lub teeb xim thiab siab pob tshab, thiab siv ntau yam. Ntxiv cov roj epoxy kua roj nyob hauv cov txheej txheem ntau lawm ntawm cov khoom lag luam PVC tsis tsuas yog muaj cov txiaj ntsig zoo ntawm PVC, tab sis kuj tuaj yeem nqus tau cov tshuaj hydrogen chloride sai los ntawm kev kub thiab lub teeb, thiaj li tiv thaiv kev ua tsis tau zoo ntxiv ntawm PVC. Ua kom ruaj khov cov nquag chlorine atoms ntawm PVC saw thiab ua raws li stabilizer.
Kev sib xyaw ntawm epoxy kua roj thiab polyester plasticizer tuaj yeem txo cov tsiv teb ntawm polyester plasticizer. Nws muaj qhov tseem ceeb synergistic thaum siv nrog hlau ua kom tshav kub, uas tuaj yeem txhim kho cov nyhuv stabilizing. Lub sijhawm no, tus nqi ntawm cov kuab hlau yuav raug txo kom txog li ib feem peb ntawm tag nrho cov nyiaj uas xav tau rau kev siv ib zaug. Vim tias kev sib raug zoo ntawm cov khoom no nrog PVC yog sib npaug rau DOP, thiab nws cov khoom siv hluav taws xob kom zoo dua li DOP, siv cov khoom no tuaj yeem txo tus nqi ntawm tag nrho cov yas hauv cov khoom. Qhov no tsis tsuas yog txo tus nqi, tab sis kuj txhim kho cov khoom' s cov ntsuas kev ntsuas, xws li kev txhim kho cov khoom' s cuam tshuam tsis kam, pob tshab, luam ntawv, weldability, thiab lwm yam.
