Product Overview
Fully Hydrolyzed Polyvinyl Alcohol (PVA) is a synthetic, water-soluble polymer produced via the alcoholysis of polyvinyl acetate. With a hydrolysis degree exceeding 98.0 percent, these grades feature higher crystallinity, excellent solvent resistance, high tensile strength, and superior film-forming capabilities compared to partially hydrolyzed variants. Dissolution requires heated water (85 degrees C or higher), yielding stable aqueous solutions with high binding power and chemical resistance.
Product Types / Grades
Selection depends strictly on solution viscosity and polymerization degree, which dictate molecular weight and mechanical performance.
| Grade Designation | Viscosity (4 percent Sol., 20 degrees C) | Degree of Hydrolysis | Volatiles (percent) | Primary Industrial Application |
| PVA-FH05 | 5 to 7 mPa.s | 98.5 percent or higher | 5.0 or less | Textile sizing, paper surface sizing |
| PVA-FH20 | 20 to 28 mPa.s | 99.0 percent or higher | 5.0 or less | High-strength adhesives, PVA fiber production |
| PVA-FH45 | 45 to 55 mPa.s | 99.3 percent or higher | 5.0 or less | Ceramic binders, specialized extrusion molding |
Key Properties & Characteristics
Thermal Stability:
Melts between 220 degrees C and 230 degrees C; thermal degradation begins above 200 degrees C.
Solubility Profile:
Insoluble in cold water, organic solvents, gasoline, and petroleum oils. Dissolves completely only in water maintained at 85 degrees C to 95 degrees C.
Mechanical Strength:
Dry films exhibit high tensile strength, high tear resistance, and exceptional flexural rigidity under low humidity.
Barrier Properties:
Exceptional oxygen, aroma, and carbon dioxide barrier performance under dry ambient conditions.
Processing & Handling
Dissolution Procedure:
Add dry resin gradually to cold water (30 degrees C or lower) under high-speed agitation to disperse particles without lumping. Heat the dispersion to 90 degrees C to 95 degrees C and maintain for 45 to 60 minutes until complete optical clarity is achieved.
Storage of Aqueous Solutions:
Store solutions in stainless steel or lined tanks. Prevent bacterial growth by using appropriate industrial biocides if storage exceeds 48 hours.
Safety & PPE:
Fine dust is combustible under airborne suspension. Use local exhaust ventilation and grounded transfer equipment to prevent electrostatic accumulation. Wear dust masks and safety glasses during handling.
Quality Control & Supply Assurance
Analytical Testing:
Every production lot is tested via Brookfield viscometer (following standard industrial testing protocols such as ISO/ASTM baseline methods) for solution viscosity, titration for residual acetate groups (hydrolysis degree), and gravimetric analysis for ash and volatile content. A Certificate of Analysis is issued for every shipment.
Traceability:
Barcoded inventory management tracks raw material input batches through continuous reactor polymerization lines.
Regulatory Compliance:
Material production and formulation conform to standard international chemical inventory requirements and safety directives.
Supply & Order Options
Minimum Order Quantity (MOQ):
1 metric ton (1,000 kg) per specification grade.
Lead Time:
14 to 21 days from order confirmation to port loading for standard container shipments.
Customization:
Custom viscosity blending, particle size reduction, and private-label multi-wall paper bag packaging available for long-term supply agreements.
Premium Fully Hydrolyzed PVA Grades
Our Fully Hydrolyzed Polyvinyl Alcohol is a high-molecular polymer characterized by its high degree of hydrolysis (typically 98-99% or 99%+). Unlike partially hydrolyzed grades, fully hydrolyzed PVA offers maximum water resistance and chemical inertness once the film is formed.
As a leading manufacturer, we provide specific grades like PVA 1799 (098-20) and PVA 0599 (098-05), ensuring excellent solvent resistance and mechanical properties for demanding industrial applications.
Max Strength
Offers the highest tensile strength and abrasion resistance among all PVA types.
Water Resistance
Excellent stability in cold water environments after proper film curing.
Chemical Stability
Resistant to oils, grease, and diverse organic solvents.

Fully Hydrolyzed PVA FAQ
What is the shelf life of Fully Hydrolyzed PVA?
When stored in a dry, cool place in original packaging, it typically maintains properties for 24 months.
Can Fully Hydrolyzed PVA be used in biodegradable films?
Yes, it is a primary material for eco-friendly, water-soluble packaging films due to its excellent gas barrier properties and biodegradability.
What is the precise temperature required to dissolve fully hydrolyzed PVA?
Complete dissolution requires water temperatures between 85 degrees C and 95 degrees C. Introducing the polymer directly into boiling water without prior cold-water dispersion will cause outer-layer dissolution and form insoluble gel lumps (fisheyes).
How does fully hydrolyzed PVA differ from partially hydrolyzed grades in adhesive formulations?
Fully hydrolyzed grades (98 percent or higher) contain fewer residual acetate groups, yielding higher tensile strength, greater chemical resistance, and lower water-reactivity once dried. Partially hydrolyzed grades dissolve in cold water and offer faster initial tack.
Can this grade be used for food-contact paper packaging?
Specific production batches comply with relevant food-contact safety standards for indirect applications. Verify intended end-use requirements prior to ordering.
What is the maximum recommended solids content for aqueous preparation?
For grades with viscosities between 20 mPa.s and 30 mPa.s, a solids concentration of 10 percent to 15 percent is standard to maintain pumpable viscosity at room temperature. Higher viscosity grades are typically prepared at 5 percent to 8 percent solids.
What documentation is provided with export shipments?
Each shipment includes a commercial invoice, packing list, Bill of Lading, regulatory compliance statement, and a lot-specific Certificate of Analysis.
Do you provide trial samples for laboratory evaluation?
Yes. 1 kg to 5 kg sample quantities are supplied for R&D evaluation accompanied by full technical data sheets, test method disclosures, and material safety documentation.
