Cov roj Silicone feem ntau tsis muaj xim (lossis lub teeb daj), tsis muaj ntxhiab, tsis mob thiab tsis hnov tsw kua. Silicone roj yog cov tsis muaj dej nyob hauv dej, methanol, ethylene glycol thiab 2-ethoxyethanol. Nws yog miscible nrog benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride lossis kerosene. Nws yog me ntsis soluble hauv acetone, dioxane, ethanol thiab Butanol. Nws muaj lub zog ua haujlwm vapor me me, lub teeb nyem siab dua thiab qhov kis ntawm cov pa taws, thiab qis dua qhov taw tes khov. Raws li tus naj npawb ntawm ntu n txawv, molecular phaus nce thiab viscosity tseem nce. Cov khoom siv roj silicone tuaj yeem muaj ntau qhov kev sib txawv, los ntawm 0.65 centistokes mus txog tsheej lab ntawm centistokes. Yog tias koj xav ua qis-viscosity silicone roj, koj tuaj yeem siv acid av nplaum ua catalyst thiab telomerize ntawm 180 ° C, lossis siv sulfuric acid ua catalyst los telomerize ntawm qhov kub tsawg los ua cov roj viscosity silicone roj lossis viscous. Alkaline catalyst.
Cov roj silicone muaj cov cua kub tsis kam, hluav taws xob rwb thaiv tsev, tiv thaiv huab cua, hydrophobicity, lub cev tsis muaj zog thiab cov nplaim hluav taws me me. Tsis tas li ntawd, nws tseem muaj qhov tsis muaj viscosity-kub coefficient, siab compression tsis kam, thiab qee hom kuj muaj hluav taws xob tsis kam. Cov.
