PVP Polymer 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.

Properties:
*Solubility in water and many oter organic solvents.
*Hygroscopicity
*Film former
*Adhesive
*Intial tack
*Complex formation
*Stabilization
*Solubilization 
*Crosslinkability
*Biological compatibility
*Toxicological safeness 

Applications:
1) In Pharmaceutical Field:
*Binder for tablets,the premier high performance binders for wet granulation.
 
*Films/Sugar coatings,act as film-forming agents,adhesion promoters and pigment dispersers.
 
*Viscosity modification,crystal inhibitors and drug solubilization in liquid formulations,such as injection and ophthalmic products.
 
*Thickening agents for aqueous-alcoholic solutions for oral and topical preparations.
 
*Improve solubility and enhances bioavailability of drug actives,used to adjust the solubility speed of some hardly soluble actives to enhance bioavailability.
 
*Pore formation in taste-masking formations,medical plastics and in other membrane production.
 
*Others,capsule flow aid,cleaning fluids for contact lenses,enzyme and sensitive medicines stabilization,cryoprotector.
2)In Cosmetic Filed:
Cosmetic Grade PVP products are suitable for fourmulations which used as film forming and viscosity modification,especially in hair styling products,mousse gels and lotions & solution,PVPs also used as dispersion agent in Hair-dying,pigment products' formulations.Thickening agent for oral and optical preparations.

3)In Hi-Tech Industries:

Technical grade PVP are being used Textiles/Fibers,Adhesives,Coatings/paintings,Laundry/Household detergent,Inks,Ceramics and other hi-tech industries.

*Dye transfer inhibition in detergents using PVP K15,K17 & K30 and/or its liquid product to complex fugitive.

*Textile dye stripping and strike rate control through compexation and dispersion with PVP K30 and/or its liquid product.

*Laundry detergents where PVP K30 inhibits soil redeposition.

*Emulsion polymerization where PVP K30 and or its liquid product latex stabilizer,functioning as a protective colloid,facilitates redispersion of a 'broken'latex end-use application.

*Dispersions using PVPK30 & K90 and/or its liquid product for nonaqueous dye and pigment-based writing ink delivery systems.

*Hollow fiber membrane manufacture in which PVP K90 & K30 and/or its liquid product create voids any hydrophilic domains in polysulfone membranes.

*In oil filed cementing,where PVP K30& K90 and or its liquid productserve as fluid loss control agents.

*On lithographic plates using hydrophobic inks,where PVPK15 provides enhancement of the nonimage area.

*PVP K80,K85 & K90 and/or its liquid products in stearate-based adhesive sticks for arts and crafts applications.

*In fiber glass sizing,using PVP K30 & K90 and/or its liquid products film forming action to promote polyivnylacetate adhesion.

*As combustible ceramic binders,using PVP K30 & K90 and/or its liquid product to enhance green strength.

*PVP K15,K17,K30,K60 & K90 and/or its liquid products used in agriculture as binder and complexation agent for crop protection,Primary film former in seed treatment and coatings.
