Product
Physical properties of polyvinylpyrrolidone: soluble - very soluble in water and halogenated hydrocarbon solvents, alcohols, amines, nitroalkanes and low molecular fatty acids, but insoluble in acetone, ether, turpentine, aliphatic hydrocarbons and alicyclic hydrocarbons. It is compatible with most inorganic salts and resins.
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
