Product name: POvidone Chemical name: polyvinylpyrrolidone CAS number: 9003-39-8 Appearance: Light yellow to white powder Water content: No more than 5% Solubility: soluble in water and a variety of organic solvents K value: 27-32.4 pH: 3-7 Physicochemical properties White or milky white hygroscopic powder; Soluble in water, alcohol, amine and other organic solvents; Excellent solubility, film formation, chemical stability and solubilization; Strong bonding and complexing ability.The molecular weight of PVPK30 is about 40,000, which is one of the most widely used homopolymer series products. Performance and applicationSolubility and solution propertiesLike all homopolymer series products, because the molecular structure of PVPK30 contains hydrophilic groups and oil groups, it can interact with many solvents, so that it can be dissolved in water, and can be dissolved in a variety of alcohols, carboxylic acids, amines and halogenated hydrocarbons and other organic solvents. The solubility is limited only by its own viscosity.PVPK30 can be\u2026<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[79],"attr":[],"class_list":["post-904","post","type-post","status-publish","format-standard","hentry","category-problems","tag-polyvinylpyrrolidone"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/904","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/comments?post=904"}],"version-history":[{"count":3,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/904\/revisions"}],"predecessor-version":[{"id":931,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/904\/revisions\/931"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=904"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=904"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=904"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=904"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
