PVP (Polyvinylpyrrolidone) K-15 polymer is a hygroscopic, amorphous polymer.
PVP K-15 is a linear nonionic polymer that is soluble in water and organic solvents, and pH stable.
PVP K-15 forms hard glossy transparent films and has adhesive and cohesive properties.
Polyvinylpyrrolidone (PVP) can be plasticized with water and most common organic plasticizers.
PVP K-15 is considered to be physiologically inert.
Applications take advantage of one or more properties inherent in the polymer, typically due to the pyrrolidone ring.
High polarity and the resultant propensity to form complexes with hydrogen donors, such as phenols and carboxylic acids, as well as anionic dyes and inorganic salts.
Dispersancy, where components in a mixture are uniformly distributed through the use of polyvinylpyrrolidone.
Hydrophilicity, where the water solubility of PVP is PVP K-15s dominant feature and frequently a factor along with other properties valuable to numerous applications.
Cohesivity, where cohesive strength is achieved through a variety of dry blending and granulation techniques.
PVP is cross-linkable to a water insoluble, swellable material either in the course of vinylpyrrolidone polymerization, by addition of an appropriate multifunctional comonomer or by post-reaction, typically through hydrogen abstraction chemistry.
Polyvinylpyrrolidone is a hygroscopic, amorphous polymer supplied as a white, free-flowing powder or a clear aqueous solution.
