PVP can serve as a gelling agent for tertiary oil recovery, improving the oil recovery rate of the oilfield. As an additive for photosensitive materials, it helps to reduce latex content and enhance the coverage ability of developing images. As a thickener, dispersion stabilizer, and bonding regulator in the process of polymer polymerization. As a dispersant in the papermaking industry and as a co catalyst in the propylene amine gasification reaction. The application of PVP in fields such as separation membranes, photocurable resins, laser discs, drag reducing coatings, building materials, steelmaking, and electroplating is also on the rise.
