The price of polyvinyl alcohol (PVA) per kilogram depends on grade, purity, and molecular weight. Industrial-grade PVA powders (e.g., PVA 2488) cost $1.5 to $2.5/kg in bulk (≥1,000 kg), while food-grade or pharmaceutical-grade PVA can reach $3 to $4.5/kg. Low-molecular-weight PVA (13–23k Da) is generally cheaper than high-molecular-weight grades (85–124k Da), which command higher prices due to stronger film properties. Factors like degree of hydrolysis (DH) also impact pricing: fully hydrolyzed PVA (DH ≥98%) is costlier than partially hydrolyzed (DH 87–89%) due to additional processing. China’s leading suppliers, such as Sichuan Vinylon and Guangzhou Minwei, offer competitive prices, with discounts for orders exceeding 10 tons. Short-term price fluctuations are influenced by raw material costs (vinyl acetate, methanol) and global supply-demand dynamics.
