Polyvinyl Alcohol (PVA) – Key Properties

Product Overview

Polyvinyl Alcohol (PVA) is a water-soluble, high-performance synthetic polymer widely used in industrial, packaging, textile, and chemical applications due to its excellent film-forming and adhesive properties.

Key Properties

1. Solubility

• Highly hydrophilic material
• Easily soluble in water (typically dissolves in hot water above 90°C)
• Insoluble in most organic solvents

2. Film-Forming Ability

• Forms strong and uniform films easily
• Excellent mechanical strength of formed films
• Strong gas barrier properties against H₂, N₂, O₂ (except water vapor)

3. Adhesion

• Good adhesion to hydrophilic materials such as:
  • Cellulose
  • Paper
  • Textile fibers
