Polyvinylpyrrolidone K90

Product Description

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 k*5,k*7 & k*0 and/or its liquid product to complex fugitive.

*textile dye stripping and strike rate control through compexation and dispersion with pvp k*0 and/or its liquid product.

*laundry detergents where pvp k*0 inhibits soil redeposition.

*emulsion polymerization where pvp k*0 and or its liquid product latex stabilizer,functioning as a protective colloid,facilitates redispersion of a 'broken'latex end-use application.

*dispersions using pvpk*0 & k*0 and/or its liquid product for nonaqueous dye and pigment-based writing ink delivery systems.

*hollow fiber membrane manufacture in which pvp k*0 & k*0 and/or its liquid product create voids any hydrophilic domains in polysulfone membranes.

*in oil filed cementing,where pvp k*0& k*0 and or its liquid productserve as fluid loss control agents.

*on lithographic plates using hydrophobic inks,where pvpk*5 provides enhancement of the nonimage area.

*pvp k*0,k*5 & k*0 and/or its liquid products in stearate-based adhesive sticks for arts and crafts applications.

*in fiber glass sizing,using pvp k*0 & k*0 and/or its liquid products film forming action to promote polyivnylacetate adhesion.

*as combustible ceramic binders,using pvp k*0 & k*0 and/or its liquid product to enhance green strength.

*pvp k*5,k*7,k*0,k*0 & k*0 and/or its liquid products used in agriculture as binder and complexation agent for crop protection,primary film former in seed treatment and coatings.
