PVA 2488L(V50) Powder Polyvinyl Alcohol Features

  • 1. Molecular Formula: (C2H4O)n. Alcoholysis degree: 88%; Polymerization degree: 2400; Molecular weight: 105600. Solubility: the solubility of PVA varies depending on its alcoholysis degree and polymerization degree.

  • 2. Polyvinyl alcohol is a water-soluble polymer derived from the hydrolysis of polyvinyl acetate, without the need for monomer polymerization. It appears as a white powder.

  • 3. Thermal Stability: PVA softens when heated and shows no significant change below 40°C. Prolonged heating above 160°C causes gradual discoloration. At temperatures above 220°C, it decomposes to water, acetic acid, acetaldehyde, and butene.

  • 4. PVA is almost unaffected by weak acids, weak alkalis, or organic solvents, and it exhibits high oil resistance. PVA is a low-viscosity polymer, and its aqueous solution is very stable at room temperature, with no degradation during storage.

  • 5. Film-Forming Properties: Due to strong intermolecular adhesion, PVA easily forms films that are colorless, transparent, and exhibit excellent mechanical strength. The film surface is smooth, non-sticky, and has good solubility. PVA films have high light transmittance, high moisture permeability, and excellent printability.
