CCP Changchun BP20 (2088) Medium-High-Viscosity Partially Hydrolyzed Polyvinyl Alcohol for Paper Coating Slurry & Chemical Fiber Sizing

Full Name: CCP Changchun BP05 Low-Viscosity Fast-Dissolving Partially Hydrolyzed Polyvinyl Alcohol (Model 0588) Low polymerization degree & medium hydrolysis industrial water-soluble polymer, designed for low-viscosity formulations with ambient-temperature fast dissolution. Widely used in mass production lines of textile, paper making, water-based adhesives and construction materials, balancing processing efficiency and formula compatibility. Core Technical Parameters Viscosity (4% aqueous solution, 20℃) 5~6 mPa·s Degree of Hydrolysis 86~89 mol% Appearance Uniform white pellets (customizable powder form) Volatile Content ≤5.0 % Ash Content ≤0.4 % pH Value (4% aqueous solution) 5~7 Purity ≥99.0 % Standard Package: 20kg paper-plastic composite bag with inner liner; 1kg trial packs available   CAS No. 9002-89-5   Core Advantages 1.  Low viscosity feature avoids excessive thickening under high loading; ensures excellent fluidity for water-based coatings & adhesives without sagging during construction. 2.  Good ambient-temperature solubility; quickly swells & disperses in 15~35℃ warm water, eliminating long-time high-temperature heating and cutting production energy consumption. 3.  Strictly controlled low ash content; resists yellowing & decomposition under high-temperature processing, leaving minimal residues after sintering for ceramics & powder metallurgy to guarantee finished product purity. 4.  Transparent, flexible formed film with resistance to grease & organic solvents; offers balanced adhesion to polar substrates including paper, textile fiber and wood. 5.  Wide formula compatibility; miscible with starch, emulsions and various water-based additives; aqueous solution stays stable without mildew or delamination during storage. 6.  Biodegradable, odor-free and eco-friendly, compatible with most compliant industrial production lines. Main Application Fields Core Applications: Short fiber textile warp sizing, paper surface sizing / pigment coating, low-viscosity water-based paper adhesive / remoistenable glue Compatible Fields: Putty & thermal insulation mortar additives for construction, ceramic green body binder, screen printing photosensitive substrate, non-woven fabric adhesive, eco-friendly water-soluble coating film-forming agent Forbidden Scenarios: Raw materials for oral food products, long-term outdoor topcoats with high weather resistance requirements, dedicated high-viscosity thick paste systems Precautions for Use 1.  Recommended dissolving process: Add pellets into room-temperature water, stir & swell for 30 mins, heat up to 60℃ and stir constantly until fully transparent. Add a small amount of silicone defoamer under high-speed stirring if needed. 2.  Store in dry & ventilated warehouse at 5~30℃; keep away from heat sources, moisture and volatile chemicals to prevent caking from moisture absorption. 3.  Standard dosage reference by formula: Textile sizing agent 3%\ 8%, paper coating 1.2%\ 3.5%, water-based adhesive 2%\ 6%, construction mortar 0.1%\ 0.5%; adjust proportion according to actual formula demand. 4.  Equip dust extraction at feeding station; wear dust masks for manual operation. 5.  This product is only used as industrial processing auxiliary agent; direct oral food contact is prohibited. Separate compliance testing is required if used for indirect food packaging contact.
