Povidone (Polyvinylpyrrolidone, PVP) is a water-soluble polymer classified into different grades according to molecular weight, including K17, K30, K60, K90, and K120. Among them, K90 belongs to the high–molecular weight category and demonstrates stronger film-forming ability, adhesion, and dispersibility in industrial applications. It is widely used in adhesive systems, functional coatings, textile auxiliaries, cleaning formulations, and certain advanced material processing applications.As global manufacturing shifts toward high-performance materials and specialty chemicals, demand for industrial-grade Povidone K90 continues to grow steadily. Compared with lower molecular weight grades, K90 provides stronger structural support in high-viscosity systems and delivers improved stability within complex formulations. Therefore, manufacturers with stable production capacity and strict quality control systems hold a clear competitive advantage in the 2026 market.
