Polyvinylpyrroldione
Product Description:
PVP K is a hygroscopic polymer ,supplied in white or creamy white powder,raning from low to high viscosity & low to high molecular weight with solubility in aqueous and organic solvents,each characterized by K Value.PVP K is Solubility in water and many oter organic solvents.,Hygroscopicity,Film former ,Adhesive,Intial tack ,Complex forma-tion,Stabilization,Solubilization,Crosslinkability ,Biological compatibility andToxicological safeness.In industrial applications including,in adhesives to improve strength and toughness;in paper manufacturer to increase strength and ascoating resin,and in synthetic fibers to improve dye receptivity.It is also widely employed in inks,imaging.lithography,detergents and soaps,the textile,ceramic,electrical,metallurgical industries and as a polymerization additive.
Polyvinylpyrollidone(PVP)Technical Grade products are existing as powder and water solution form,and being supplied in a wide molecular weight range,easily dissolve in water,alcohol and other organic solvents.They are highly hygroscopicity,excellent film-forming capacity,adhesiveness and chemical stability,none toxicity.
