Alcool polyvinylique (PVA) : la science derrière ses diverses applications
janvier 21, 2025 •Polyvinyl Alcohol (PVA) is a versatile polymer with tunable properties based on its degree of polymerization (DP) and degree of alcoholysis (DH). High DP PVA results in high viscosity and strength, suitable for applications like textile sizing and high-strength adhesives. Low DP PVA offers low viscosity and fast dissolution, ideal for low-viscosity adhesives and cosmetics. Low DH PVA provides excellent water solubility, making it suitable for textile sizing and water-soluble films. High DH PVA exhibits excellent water resistance and chemical stability, used in food packaging and pharmaceuticals.
