Lub Hoobkas nto moo zoo Poly (1-vinylpyrrolidone-co-vinyl acetate) / VP / VA CAS: 25086-89-9
Ua ntej thiab qhov tseem ceeb tshaj plaws, qhov copolymer no muaj cov yeeb yaj kiab zoo heev.Nws tuaj yeem tsim cov yeeb yaj kiab meej nrog adhesion zoo thiab ua haujlwm ntev.Qhov no ua rau nws zoo tagnrho rau coatings thiab adhesives siv nyob rau hauv ntau yam kev siv xws li xim, varnishes thiab varnishes.
Tsis tas li ntawd, vinylpyrrolidone-vinyl acetate copolymers pom zoo solubility hauv dej thiab ntau yam organic solvents.Qhov solubility no tso cai rau nws siv los ua tus neeg sawv cev thickening nyob rau hauv ntau yam formulations, nrog rau cov khoom tu tus kheej xws li cov plaub hau gels, tshuaj tsuag thiab tshuaj pleev.Cov khoom nplaum zoo heev ntawm cov copolymer no kuj ua rau nws muaj txiaj ntsig zoo hauv kev tsim cov ntsiav tshuaj thiab tshuaj ntsiav rau kev lag luam tshuaj.
Tsis tas li ntawd, cov conductivity ntawm vinylpyrrolidone-vinyl acetate copolymer tuaj yeem hloov kho raws li cov kev xav tau tshwj xeeb, ua rau lawv tsim nyog rau kev siv hluav taws xob thiab kev siv txheej txheej.Nws compatibility nrog ntau yam substrates xws li hlau, plastics thiab textiles ntxiv rau nws versatility thiab siv tau.
Tsis tas li ntawd, vinylpyrrolidone-vinyl acetate copolymer yog thermally ruaj khov thiab tiv taus UV hluav taws xob, ua kom muaj zog thiab ua haujlwm ntev rau kev siv sab nraum zoov.Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv txheej ntawm cov tsev, tsheb thiab cov khoom siv hluav taws xob.
Hauv cov ntsiab lus, vinylpyrrolidone-vinyl acetate copolymers muaj cov khoom ua yeeb yaj kiab zoo heev, solubility, hluav taws xob conductivity, thiab thermal stability, muab ntau qhov ua tau zoo rau kev lag luam sib txawv.Nws cov ntawv thov muaj xws li cov coatings thiab adhesives rau cov khoom tu tus kheej thiab cov khoom siv hluav taws xob.Peb ntseeg siab tias peb cov vinylpyrrolidone-vinyl acetate copolymers yuav ua tau raws li koj qhov kev cia siab nrog lawv cov kev ua tau zoo thiab kev ua tau zoo.
