Cellulose ethers yog cov khoom dawb los yog lub teeb daj, feem ntau nyob rau hauv granular los yog hmoov daim ntawv (cov dej noo txog li 10%). Qhov pom meej ntom ntom ntawm cov hmoov yog los ntawm 0.3 mus rau 0.5 g/cm3. Qhov pom tseeb ntawm qee cov khoom muaj fiber ntau yog tsawg dua 0.2 g / cm3.
Nyob ntawm daim ntawv thov, manufacturers tuaj yeem kho cov qib purity sib txawv. Cov khoom siv purity siab tsis muaj ntxhiab thiab tsis qab. Cov khoom uas tsis kho yuav muaj txog li 40 wt% ntawm sodium ntsev, xws li NaCl. Cov additives tuaj yeem muab sib xyaw rau hauv cov khoom raws li xav tau los xyuas kom meej nws ruaj khov, tswj solubility thiab ua haujlwm yooj yim. Tsis tas li ntawd, feem ntau cov khoom lag luam cellulose ethers tuaj yeem tov nrog lwm cov dej-soluble polymers, xws li cov khoom lag luam starch, natural resins lossis polyacrylamide, kom tau txais cov khoom sib xyaw nrog cov khoom tsim nyog thiab lwm yam khoom siv lub cev.
