VP/VA Copolymer
VP/VA Copolymers tsim cov pob tshab, hloov tau, oxygen permeable films uas ua raws li iav, yas thiab hlau.Vinylpyrrolidone/Vinyl acetate (VP/VA) resins yog linear, random copolymer tsim los ntawm cov dawb-radical polymerization ntawm cov monomers nyob rau hauv sib txawv ratios.VP/VA Copolymers muaj nyob rau hauv cov hmoov dawb los yog ntshiab tov nyob rau hauv ethanol thiab dej.VP / VA copolymer yog dav siv los ua cov yeeb yaj kiab qub vim tias lawv cov yeeb yaj kiab yooj yim, zoo adhesion, luster, dej remoistenability thiab hardness.Cov khoom no ua rau PVP / VA copolymers haum rau ntau yam kev lag luam, kev saib xyuas tus kheej thiab cov khoom siv tshuaj.
