RS-24S Polyvinyl Alcohol PVA Medium-High Viscosity Water-Soluble Resin Adhesive Construction Paper Grade

Full Name & Product Positioning Full Product Name:  RS-24S Polyvinyl Alcohol RS-24S is a medium-high viscosity grade polyvinyl alcohol offering water solubility, film-forming properties, and adhesive strength. Based on industry naming conventions for comparable grades, its viscosity level approximately corresponds to the 44-50 mPa·s range and its degree of hydrolysis to approximately 86-89 mol%, making it suitable for adhesives, construction additives, and paper converting applications. Note: Specific technical parameters for this product should be confirmed against the manufacturer's official TDS document; data in this document are industry reference values. Core Technical Parameters (Reference Values — Subject to Manufacturer TDS) Parameter Reference Value Product Type Partially hydrolyzed polyvinyl alcohol Viscosity (4% aqueous soln., 20°C) Approx. 44 - 50 mPa·s (pending confirmation) Degree of Hydrolysis Approx. 86 - 89 mol% (pending confirmation) Volatile Matter ≤5.0 wt% pH (4% aqueous soln.) 5.0 - 7.0 Appearance White granules / powder CAS Number 9002-89-5 Standard Packaging 20kg/bag Key Advantages (Based on general performance characteristics of comparable PVA products; specific performance is subject to manufacturer TDS and actual formulation validation.) 1.  Medium-high viscosity grade provides relatively high aqueous adhesive strength and corresponding film toughness; 2.  Partially hydrolyzed structure allows cold-water dispersibility and hot-water solubility, offering good dissolution process compatibility; 3.  Offers corresponding adhesive strength to cellulosic and porous substrates; 4.  Suitable for construction mortar thickening and water retention, paper bonding, and textile sizing applications; 5.  Specific performance indicators should be confirmed against the manufacturer's TDS; small-scale trial testing is mandatory before production use. Main Application Areas Core Applications:  Adhesives, construction mortar additives, paper converting, textile sizing Compatible Applications:  Woodworking adhesives, fiberboard binders, emulsion protective colloids, ceramic binders Not Recommended For:  Food or oral-ingestion articles, high-precision electronic-grade applications (requires separate validation)
