Poly(vinyl alcohol), MW 108,000, 99+% hydrolyzed, also known as PVA or PVOH, is a high-hydrolysis, water-soluble synthetic polymer used in films, coatings, adhesives, binders, textile sizing, paper processing, emulsion stabilization, and specialty formulation work.
Synonyms / related names: PVA; PVOH; polyvinyl alcohol; poly(vinyl alcohol).
This grade has an approximate molecular weight of 108,000 and is 99+% hydrolyzed. Higher hydrolysis grades generally require progressively more energy to dissolve because increased hydrolysis can increase crystallinity and hydrogen bonding.
Researchers, formulators, and industrial users may use poly(vinyl alcohol) in water-soluble films, coating systems, adhesive and binder formulations, textile and paper treatments, emulsion polymerization, dispersions, and hydrogel-related materials research.

Applications
Films & Coatings
Poly(vinyl alcohol) may be used in water-soluble films and coating systems where film formation, hydrogen bonding, and controlled water interaction are important formulation considerations.
Adhesives & Binders
PVA is commonly used in adhesive and binder formulations for paper, textile, wood, and specialty material systems where water solubility and polymer film strength are required.
Textile & Paper Processing
This polymer may be used as a sizing agent or surface treatment polymer in textile and paper processing workflows where fiber interaction, surface strength, and coating uniformity are evaluated.
Emulsion Polymerization & Stabilization
Poly(vinyl alcohol) may function as a protective colloid in emulsion polymerization and dispersion systems where polymeric stabilization is needed.
Hydrogel & Materials Research
PVA may be used in hydrogel-related and specialty materials research where water solubility, hydroxyl functionality, and film-forming behavior are relevant to the application.
Solubility & Processing Considerations
- 99+% hydrolyzed PVA typically requires more energy to dissolve than lower-hydrolysis grades
- Dissolution depends on water temperature, mixing intensity, particle wetting, concentration, and batch size
- Hydrogen bonding and crystallinity influence solubility, film strength, and water interaction
- Compatibility should be evaluated with plasticizers, salts, surfactants, pigments, fillers, and other formulation components
- Final film and coating properties depend on concentration, drying conditions, substrate, and additive package
Final performance should be confirmed under the user’s specific formulation and processing conditions, including dissolution method, solids level, temperature profile, drying conditions, and intended end use.
Preparation Tips
- Add gradually to water with adequate agitation to reduce clumping
- Use controlled heating and mixing when preparing aqueous solutions
- Allow sufficient time for complete hydration and dissolution
- Avoid rapid dumping of powder into water, which can form difficult-to-dissolve agglomerates
- Run small-scale dissolution and compatibility trials before production or process transfer
Handling & Storage
- Store at room temperature
- Keep container tightly closed when not in use
- Use good ventilation and standard laboratory or industrial safety practices
- Avoid unnecessary dust generation during powder handling
- Wear protective gloves and safety glasses when appropriate
- Refer to the Safety Data Sheet before handling

1. What is Poly(vinyl alcohol), MW 108,000, 99+% hydrolyzed used for?
Poly(vinyl alcohol), MW 108,000, 99+% hydrolyzed is used in films, coatings, adhesives, binders, textile sizing, paper processing, emulsion stabilization, dispersions, and hydrogel-related materials research.
2. What is the molecular weight of this PVA product?
The listed molecular weight is approximately 108,000.
3. What does 99+% hydrolyzed mean?
99+% hydrolyzed refers to a high degree of hydrolysis, meaning most acetate groups from the parent poly(vinyl acetate) have been converted to hydroxyl groups in the poly(vinyl alcohol) structure.
4. Why can high-hydrolysis PVA require more energy to dissolve?
Higher hydrolysis grades can have greater crystallinity and stronger hydrogen bonding, which may require more heat, mixing, or dissolution time compared with lower-hydrolysis PVA grades.
5. How should Poly(vinyl alcohol), MW 108,000, 99+% hydrolyzed be stored?
Store Poly(vinyl alcohol), MW 108,000, 99+% hydrolyzed at room temperature with the container tightly closed. Review the Safety Data Sheet for complete storage, handling, and personal protective equipment guidance.
Safety & Documentation
