Chang Chun CCP BP-24S Polyvinyl Alcohol PVA Fine Powder 80 Mesh Medium-High Viscosity 88% Hydrolysis Adhesive Construction Grade

Full Name & Product Positioning Full Product Name:  Chang Chun Petrochemical (CCP) BP-24S Partially Hydrolyzed Polyvinyl Alcohol Fine Powder BP-24S is a fine-powder grade polyvinyl alcohol in the Chang Chun BP series, featuring partial hydrolysis (86-89 mol%) and medium-high viscosity (44-50 mPa·s), with particle size passing through an 80-mesh screen. Compared to the granular BP-24 grade, the fine powder form offers faster dissolution and better dispersibility, making it particularly suitable for dry-mix mortars, construction additives, and adhesive applications requiring rapid dissolution. Core Technical Parameters Parameter Typical Value Product Type Partially hydrolyzed PVA (fine powder grade) Viscosity (4% aqueous soln., 20°C) 44 - 50 mPa·s Degree of Hydrolysis 86 - 89 mol% Volatile Matter ≤5.0 wt% Ash Content ≤0.5 wt% pH (4% aqueous soln.) 5.0 - 7.0 Particle Size Passes 80-mesh screen Appearance White fine powder CAS Number 9002-89-5 Standard Packaging 20kg/bag Key Advantages (Performance based on measured conditions from original manufacturer TDS. Actual results vary with formulations and do not guarantee end-use performance.) 1.  80-mesh fine powder form offers a large specific surface area, providing better cold-water dispersibility and faster dissolution than granular products; 2.  Medium-high viscosity grade delivers high aqueous adhesive strength and corresponding film toughness and tensile strength; 3.  Partially hydrolyzed structure provides corresponding adhesive strength to cellulosic substrates and porous construction materials; 4.  Fine powder form can be directly used in dry-mix mortar premixes without pre-dissolution, offering construction convenience; 5.  Quality is stable, with batch-to-batch viscosity and hydrolysis variations controlled within manufacturer specification ranges. Main Application Areas Core Applications:  Dry-mix mortar additives, construction adhesives, paper converting adhesives, textile sizing agents Compatible Applications:  Woodworking adhesives, fiberboard binders, emulsion protective colloids, ceramic binders, gypsum board additives Not Recommended For:  Food or oral-ingestion articles, room-temperature instant-dissolution scenarios requiring extremely fast dissolution (select a lower viscosity grade)
