Description

Poly(Vinyl Alcohol) is a synthetic, water-soluble polymer renowned for its excellent film-forming, emulsifying, and adhesive properties. Its unique combination of high tensile strength, flexibility, and biodegradability makes it a critical material across numerous advanced manufacturing sectors. This versatile polymer is essential for industries ranging from high-performance textiles and paper coatings to pharmaceutical formulations and construction materials.

Application

• Adhesive & Binder Formulations: A key component in water-based adhesives for paper, wood, and textiles, as well as a binder in ceramics, refractories, and electrode manufacturing.
• Polymer & Textile Processing: Used as a sizing agent for synthetic yarns (e.g., polyester, nylon) and as a warp sizing to protect fibers during weaving.
• Paper Coating & Surface Sizing: Enhances paper strength, surface gloss, ink receptivity, and grease/oil resistance in high-quality packaging and printing papers.
• Pharmaceutical & Personal Care: Serves as a film-forming agent in tablet coatings, a viscosity modifier in ophthalmic solutions, and a stabilizer in emulsion-based cosmetics.
• Construction & Building Materials: Functions as a thickener and water-retention agent in cementitious products, tile adhesives, and joint compounds.
• Polymerization & Emulsion Stabilizer: Acts as a protective colloid and stabilizer in the suspension polymerization of vinyl acetate and other monomers.

Quality Control

Our Poly(Vinyl Alcohol) is manufactured under a stringent quality management system. Each batch is tested against critical parameters including degree of hydrolysis, viscosity, and residual acetate content to ensure consistent performance and reliable supply. Certificates of Analysis (COA) detailing purity, physical properties, and compliance with relevant industrial or food contact standards (where applicable) are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent caking or lump formation due to moisture absorption.
