Buy High Quality High Purity 99% Povidone(PVP K12/PVP K17/PVP K25/PVP K30/PVP K90) 9003-39-8 Powder In Medicine with competitve price and Fast Delivery. Polyvinylpyrrolidone (PVP), also known as polyvidone or povidone, is a synthetic water-soluble polymer derived from the monomer N-vinylpyrrolidone.is a 9003-39-8 Good Supplier In China, We supply Cosmetics Grade PVP.
Appearance: White or cream white flowable powder, odorless or slightly chemical-characterized smell. PVP exists as a white to off-white hygroscopic powder that is soluble in water.
Properties:
Nontoxic; Non-irritant; Hygroscopic; Free soluble in water, alcohol, ammonia and most of other organic solvent.
Excellent solubility, film-forming, chemical stability, physiological inert, complexation & binding property.
Product grade: Electronic-using grade.
Models: Products are classified according to their K-values, which was calculated based on polymer molecular weight & viscosity of PVP solution.
Noted:
1. K-value was converted from kinematic viscosity of 1% PVP solution.
Average viscosity molecular weight was calculated by using Mark-Houwink formula.
2. K30 approval number: (95) MPN F-01.
Product advantage: Moisture content of PVP is effectively controlled lower than 2%.
Application: Dispersant in Carbon nano-tube (CNT) conductive paste.
Dispersant in graphene conductive paste.
Dispersant in composite conductive paste (CNT+Graphene).
Found in gels, mousses, styling creams/lotions, hair colorants, pomades, waxes, pastes, and electrospinning.
Carbon nano-tube conductive paste
Adding PVP as dispersant for production of conductive paste.
Two beakers of suspensions of CNT conductive paste were used to verify the dispersive capacity of PVP K30. One beaker of suspension with addition of PVP K30 (Sample A), while the other one didn't (Sample B). These two samples were took out for comparison after placement of 96 hours. Sample A kept staying as uniform suspension, while sample B was obviously stratified. PVP K30 was validated an very effective dispersant to produce stable CNT conductive paste.
