Copovidone waa polymer-biyood-milmi leh oo loo isticmaalo in lagu wanaajiyo qaadashada iyo rarista daroogada ee dawooyinka kala duwan, oo ay ku jiraan balasmaha ka hortagga uurka.
Poly (1-vinylpyrrolidone-co-vinyl acetate) waa alaabta ceeriin ee ugu weyn ee la isku qurxiyo waxaa loo isticmaalaa jel timaha, mousse, shaambo, iwm, iyo sidoo kale surfactants, daawooyinka iyo ujeedooyin kale oo warshadaha. Inta badan waxa loo isticmaalaa sida xabag biyo-milmi leh iyo koollo qallalan oo ku jira granulation iyo tignoolajiyada tooska ah ee looxa, sida walxaha samaynta filimada ee daahanka filimka, iyo sida walxaha samaysa dalool ee walxaha waji-xidhka. Waxa loo isticmaalaa daaha sonkorta si looga hortago dildilaaca. Buugga kiimikaad ee dahaarka hoose waxa loo isticmaalaa ujeedooyin aan qoyaanka lahayn. Alaabooyinka taxanaha ah ee Vp/va copolymer waxa inta badan loo isticmaalaa sida wakiilada samaynta filimada iyo wakiilada qaabaynta ee goobta isqurxinta, gaar ahaan walxaha qarxa, jelka timaha, mousse iyo alaabta taxanaha shaambo. Waxay door muhiim ah ka ciyaaraan sida wakiilka samaynta filimada iyo wakiilka timaha habaynta. Haddii si wadajir ah loo isticmaalo pvpk30, saameyntooda isticmaalku waa la wanaajin doonaa.
Muuqaalku waa budo cad ama dareere aan midab lahayn. Nooca caadiga ah waa PVP-64.
