Polyvinylpyrrolidone Feso'ota'i PVPP Cas 25249-54-1
Polyvinylpyrrolidone cross-linked (PVPP) o se polymer fesoʻotaʻi e le mafai ona faʻaogaina i le vai, malosi malosi, faʻavae malosi, ma soʻomea faʻaletino lautele, na faia e le polymerization o vinyl pyrrolidone monomers i lalo o tulaga faʻapitoa. I le avea ai o se mea tau vailaʻau lelei polymer, PVPP e tele mea lelei ma tulaga ese, ma ua faʻaaogaina lautele i mea teuteu, meaʻai, vailaʻau ma isi fanua.

PVPP, e pei o se mea taua polymer oloa kemikolo lelei, e tele mea lelei ma tulaga ese, ma ua faʻaaogaina lautele i mea teuteu, meaʻai, vailaʻau ma isi fanua. Ona o le maualuga o le mole mole mamafa ma le fesoʻotaʻiga fesoʻotaʻiga o le polyvinylketone fesoʻotaʻi, e le mafai ona faʻafefe i le vai ae mafai ona vave faʻatupuina lona fausaga fesoʻotaʻiga e faʻalauteleina ma faʻaleagaina pe a feagai ma vai. O le PVPP o loʻo faʻaaogaina lautele e fai ma sui faʻamaʻi mo papa i vailaʻau, faʻapea foʻi ma se faʻamautu faʻamalolo, o se mea faʻalavelave faʻapitoa mo vaega vailaʻau, ma se faʻalavelave faʻalavelave mo tannins ma polyphenols i vailaʻau faʻavae.
