Polyvinyl alcohol yog ib qhov polymer siv ntau yam uas muaj siv txoj hauv qab chaw thiab txoj hauv paus, xws li kev nyiaj sib thooj, kev ua kom sov, thiab kev tso tsis pub rau huab cua thiab organic solvents. Muab los ntawm powder, granule, lossis flake form, nws sib tau rau hauv dej los tsim cov solution qhia thiab nyob. Polyvinyl alcohol siv ntau hauv kev tsim kho tshuab, kev sau ntaub, siv tshuab siv tshuab, kev sib ntxiv, duab, thiab kev sau ntaub. Hauv tshuab siv tshuab, nws pab tso zog tso siab dua thiab tso tsis pub rau kev ruaj. Hauv kev sau ntaub, nws pab tso siab dua thiab tso siab dua rau yarn. Nws tsim nyog thiab kev siv ntau yam yog qhov tsim nyog rau ob qho tshuab thiab neeg siv. Rau kev siv ntau yam lossis lwm yam kev nug ntxiv, yuav tsum muaj kev pab pawg.
