Application
It is medium-high viscosity partially hydrolyzed polyvinyl alcohol. It combines strong adhesive force, flexible film-forming performance and wide compatibility, suitable for oilfield engineering, construction, textile, coating and fine chemical sectors.
- Soil Improvement Agent: Eco-friendly soil stabilizer applied to sand fixation, slope stabilization and ecological rehabilitation projects.
- Wet Adhesives: Key raw material of high-toughness water-based adhesives for stable bonding of wood, paper and porous substrates.
- Warp Sizing: All-purpose sizing additive for high-count yarns, raising yarn abrasion resistance and overall weaving efficiency.
- Water-soluble PVA Film: Feedstock for manufacturing tough, smooth functional water-soluble films with balanced mechanical performance.
- PVAC Emulsion Protective Colloid: Stabilizes vinyl acetate emulsion polymerization and upgrades the flexibility, water resistance and service life of dried emulsion films.
- Industrial Dispersant: Maintains steady suspension of inorganic pigments and fine industrial powders and avoids particle agglomeration.
- Coatings & Adhesives Additive: Functions as a thickener and film former to optimize leveling, hardness and stability of waterborne coatings and glues.
