Kev piav qhia
Dioctyl sebacate, tseem hu ua bis-2-ethylhexyl sebacate, los yog DOS luv luv, yog tau los ntawm esterification ntawm sebacic acid thiab 2-ethylhexanol. Haum rau polyvinyl chloride, vinyl chloride copolymer, nitrocellulose, ethyl cellulose thiab hluavtaws roj hmab. Nws muaj kev ua haujlwm siab plasticizing thiab tsis tshua muaj hluav taws xob, tsis yog tsuas yog muaj kev tiv thaiv zoo heev, tab sis kuj muaj cov cua sov zoo, lub teeb ua haujlwm thiab hluav taws xob rwb thaiv tsev, thiab muaj lubricity zoo thaum rhuab, kom cov tsos thiab kev xav ntawm cov khoom zoo, tshwj xeeb tshaj yog tsim rau kev ua kom txias-resistant hlau thiab cable cov ntaub ntawv, khoom tawv tawv, films, daim hlau, nplooj ntawv, thiab lwm yam. Tsis tas li ntawd, cov khoom kuj tseem siv los ua lubricating roj thiab cov khoom siv roj thiab cov khoom siv hluav taws xob. Cov khoom yog non-toxic. Cov koob tshuaj ntawm 200mg / kg tau muab sib xyaw rau hauv cov khoom noj thiab pub rau nas rau 19 lub hlis, thiab tsis muaj tshuaj lom thiab tsis muaj carcinogenicity. Nws tuaj yeem siv rau hauv cov khoom ntim khoom noj.
