PVP K-90 is a hygroscopic, amorphous polymer supplied as a white, free-flowing powder or a clear aqueous solution.Available in several molecular weight grades, they are characterized by K-value, and used in a great variety of applicationsPvp can be plasticized with water and most common organic plasticizers. lt is considered to be physiologically inerts:
Applications take advantage of one or more properties inherent in the polymer, typically due to the lactam ring.High polarity and the resultant propensity to form complexes with hydrogen donors, such as phenols and carboxylic acids, as welas anionicdyes and inorganic salts.
Dispersancy, where components in a mixture are uniformly distributed through the use of polyvinylpyrrolidone.Hydrophilicity, where the substantial water solubility of polwinylpyrrolidone is its dominant feature and frequently a factor along with otherproperties valuable to numerous applications.
Adhesion, taking advantage of the hicher molecular weight polwinylpyrrolidones formulating in aqueous media, then evaporating suficientwater to generate a solid product for the desired application.Cohesivity, where cohesive strength is achieved through a variety of dry blending and granulation techniques.'yp is cross-inkable to a water insoluble. swelable materia either in the course of vinviyrolidone polvmerization. by addition of anappropriate multifunctional comonomer or by post-reaction, typically through hydrogen abstraction chemistry.
