H1: Polyvinyl Alcohol (PVA) 1799
What is Polyvinyl Alcohol PVA 1799?
Polyvinyl Alcohol PVA 1799 is a high-viscosity, high-degree polymerization PVOH grade designed for applications requiring excellent film strength, superior bonding performance, and high mechanical stability.
Compared with medium grades, PVA 1799 delivers:
- Higher tensile strength
- Better film-forming capability
- Improved chemical resistance
- Enhanced adhesion performance
It is widely used in textiles, adhesives, paper coating, construction additives, and water-soluble films.
