Applications:
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.
