Dioctyl Sebacate, tseem hu ua BIS-2-Ethylhexyl Sebacate, lossis Dos luv luv, yog tau los ntawm eserification ntawm sebaR acid thiab 2-Ethylhexanol. Haum rau polyvinyl chloride, vinyl chloride copolymer, nitrocellulose, tshuaj phais tshuaj thiab hluavtaws roj. It has high plasticizing efficiency and low volatility, not only has excellent cold resistance, but also has good heat resistance, light resistance and electrical insulation, and has good lubricity when heated, so that the appearance and feel of the product are good, especially It is suitable for making cold-resistant wire and cable materials, artificial leather, films, plates, sheets, etc. In addition, the product is also used as lubricating oil and lubricating grease for jet engine and stationary liquid for gas chromatography. Cov khoom lag luam tsis yog tshuaj lom. Qhov ntau npaum li cas ntawm 200mg / kg tau sib xyaw ua ke rau hauv kev pub thiab pub rau nas rau 19 hlis, thiab tsis muaj cov txiaj ntsig tshuaj lom thiab tsis pom muaj cov txiaj ntsig carcinogenicity tau pom. Tuaj yeem siv rau hauv cov ntaub ntawv ntim khoom noj.
Tsis muaj xim rau cov kua daj ua kua daj, insoluble hauv dej, soluble hauv ethanol, ether, benzene thiab lwm yam kuab tshuaj organic. Nws tuaj yeem sib xyaw nrog Ethyl cellulose, polystylene, polyvinyl corulene, Vinyl Cloetate Copolymer, thiab lwm yam, thiab muaj qhov txias txias.
