Product
This product is white or milky white powder, odorless or slightly characteristic odor, basically tasteless, insoluble in water, alkali, acid and organic solvents. It has hygroscopicity and absorbency. It swells after absorbing water, but it does not form a gel. After absorbing water, the molecular chain elongate and the volume increases rapidly, resulting in the expansion of Zhuang Li, which can disintegrate tablets quickly.
The aqueous solution of pvpk90 is non thixotropic in most cases and has a short relaxation time. When the concentration is very high, it will have a certain structural viscosity; when the shear force is increased, the viscosity will decrease. Controlling
N-vinylturrolidone is active in chemical properties and easy to be hydrolyzed and polymerized.
Like all homopolymer series products, pvpk30 contains hydrophilic and oleophilic groups in its molecular structure, which can interact with many solvents, making it soluble in water, a variety of alcohols, carboxylic acids, amines, halogenated and other o
Brownish yellow or reddish brown shaped powder, with a light special smell, soluble in water and ethanol, insoluble in diethyl ether and chloroform, good stability, no irritation, strong killing effect on bacteria, viruses, fungi, molds and spores, it is
As a kind of synthetic water-soluble polymer compound, PVP has the general properties of water-soluble polymer compound, such as colloidal protection, film-forming, adhesion, hygroscopicity, solubilization or coagulation, but its characteristics, so peopl
