Description

Poly(Vinyl Alcohol) (CAS NO 9002-89-5) is a versatile, water-soluble synthetic polymer renowned for its excellent film-forming, emulsifying, and adhesive properties. Its unique combination of biodegradability, chemical resistance, and non-toxic nature makes it a critical material for demanding industrial and specialty applications. This polymer is essential for manufacturers in sectors including adhesives, textiles, paper, and pharmaceuticals, where performance and reliability are paramount.

Application

• Adhesive & Binder Formulations: A key component in water-based adhesives for paper, wood, and textiles, and as a binder in ceramics and building materials.
• Polymer & Chemical Processing: Acts as a protective colloid in emulsion polymerization (e.g., for PVC) and as a starting material for the production of polyvinyl butyral (PVB).
• Paper & Packaging Coatings: Used in coatings and sizing to improve strength, grease resistance, and printability of paper and paperboard.
• Textile Sizing & Finishing: Serves as a warp sizing agent for yarns and as a finishing agent to modify fabric handle and appearance.
• Pharmaceutical & Personal Care: Employed as a film-forming agent in tablet coatings, topical films, and as a thickener/stabilizer in cosmetics.
• Construction & Building Materials: Functions as a cement and mortar additive to improve workability, water retention, and adhesion.

Quality Control

Our Poly(Vinyl Alcohol) is produced under a stringent quality management system. Each batch is tested against critical parameters including degree of hydrolysis, viscosity, and purity to ensure consistent performance and reliable supply. Certificates of Analysis (COA) documenting full specifications are provided with every shipment. We can supply grades meeting various industrial standards, and custom specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and caking.
