In the field of environmental water treatment, povidone K30, as a film-forming porogen, has become an indispensable material in membrane separation processes for wastewater treatment and water purification.

In the paper industry, povidone can improve the wet strength of paper and serves as an important auxiliary agent in deinking, pulping, and coloring, enhancing paper gloss, printability, and grease resistance. In the textile industry, povidone can bind with hydrophobic fibers such as polyacrylonitrile, polyester, nylon, and fibrous materials, greatly improving their dyeability. In addition, povidone can be used as an anti-soil agent, stripping agent, rapid dye reducing agent, and a buffer and dispersant for pigments. These applications provide paper and textile enterprises with more efficient and environmentally friendly production solutions, driving technological progress in the industries.

In the field of specialty coatings, the double bond structures of the polyamide and vinyl molecules in povidone determine its affinity with certain coatings and pigments. This enhances tinting strength, improves the water resistance of water-based coatings, and optimizes their flow and film-forming properties, resulting in coatings that are non-sagging, have good water resistance, form a hard film, do not peel off, and possess stain resistance.
