Chang Chun CCP BP-17S Polyvinyl Alcohol PVA Fine Powder 80 Mesh Medium Viscosity 88% Hydrolysis Adhesive Construction Paper Grade

Full Name & Product Positioning Full Product Name:  Chang Chun Petrochemical (CCP) BP-17S Partially Hydrolyzed Polyvinyl Alcohol Fine Powder BP-17S is a fine-powder grade polyvinyl alcohol in the Chang Chun BP series, featuring partial hydrolysis (86-90 mol%) and medium viscosity (20-26.5 mPa·s), with particle size passing through an 80-mesh screen. The combination of medium viscosity and fine powder form balances solubility and adhesive strength, making it widely used in construction dry-mix mortars, paper adhesives, and textile sizing applications. Core Technical Parameters Parameter Typical Value Product Type Partially hydrolyzed PVA (fine powder grade) Viscosity (4% aqueous soln., 20°C) 20.0 - 26.5 mPa·s Degree of Hydrolysis 86.0 - 90.0 mol% Volatile Matter ≤7.0 wt% Sodium Acetate ≤2.8 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 fast dissolution and can be directly used in dry-mix premix formulations; 2.  Medium viscosity grade balances adhesive strength and construction rheology, suitable for various construction and paper applications; 3.  Partially hydrolyzed structure provides good cold-water dispersibility and complete hot-water dissolution, with relatively high aqueous solution clarity; 4.  Offers corresponding adhesive strength to paper, wood, cotton fibers, and porous construction substrates; 5.  Uniform fine powder particle size provides good mixing and dispersion with other dry powder components, reducing agglomeration. Main Application Areas Core Applications:  Dry-mix mortar additives, paper converting adhesives, textile sizing agents, construction adhesives Compatible Applications:  Woodworking adhesives, fiberboard binders, protective colloid for vinyl acetate emulsion polymerization, ceramic binders Not Recommended For:  Food or oral-ingestion articles, high water-resistance requirements without post-treatment coatings
