Product Advantages
- One grade, multiple industries — Covers paper, textile, coatings, functional materials, and film-related applications with a single product.
- Processing-friendly format — Supplied as a white powder (or granules depending on supply), convenient for storage, weighing, and blending.
- Stable performance profile — Chemical stability in organic solvent environments helps improve formulation robustness.
- Better tolerance to oily systems — Insolubility in oils/grease helps maintain integrity where fatty media are present.
- Application-proven use cases — Commonly used as sizing agent, adhesive raw material, and dispersing/emulsifying component.

Product Applications
PVA-1788 White Powder Polyvinyl Alcohol is mainly used for:
Paper sizing agent
Warp sizing in textile
Adhesive
Raw material of polyvinyl alcohol panel and PVA thin film
Paint and Coatings
Medicine、cosmetic and functional materials
Emulgator and dispersing agent
Dissolving Method:
1.Fill the dissolving tank with a certain amount of water; keep the water temperature below 30°C.
2.Start the mixer, then add PVA slowly; the recommended feeding rate is about 10 kg/min.
3.Ensure the PVA powder is fully dispersed, typically 10–20 minutes.
4.After dispersion, heat the solution; it will dissolve completely when heated to 90°C for about 1 hour.
