Li-cellulose ethers li fana ka viscosity e ntle haholo ho seretse se metsi, li eketsa haholo bokhoni ba ho tlamahane ha seretse se metsi ho substrate le ho ntlafatsa ho hanyetsa ho senyeha ha seretse, 'me li sebelisoa haholo ho lilakhang seretse, seretse se kopanyang litene le mekhoa ea ho kenya letsoho ka ntle.Tšusumetso e ntseng e eketseha ea cellulose ether e ka boela ea eketsa bokhoni ba ho thibela ho qhalakanngoa le homogeneity ea thepa e sa tsoa tsoakoa, ho thibela delamination ea lintho tse bonahalang, karohano le secretion ea metsi, 'me e ka sebelisoa ka konkreite ea fiber, konkreite e ka tlas'a metsi le konkreite e ikemetseng.
