High-viscosity, partially hydrolyzed polyvinyl alcohol for diverse applications.
Polyvinyl Alcohol Grade 22-88, PVA 217, Elvanol 52-22
PVOH Solution PreparationPolyvinyl Alcohol grade 22-88 is a water-soluble polymer produced by the alcoholysis of polyvinyl acetate. It has a viscosity of approximately 22 cps in a 4% solution. This polymer is widely used as a binder in sizes due to its excellent penetration and adhesion properties on various fibrous materials. Its remarkable film characteristics include high cohesion, toughness, low electrostatic charging, and redissolving capacity in water. PVOH 22-88 offers excellent barrier properties, repelling oil, grease, and fat due to its insolubility in most organic solvents. It enhances mechanical strength when applied as a film on paper or paperboard, making it an ideal surface sizing agent. It also serves as an outstanding carrier for optical brightening agents and pigments. This grade can replace Elvanol® 52-22, Poval 26-88, Selvol 523, and PVA-217 with comparable viscosity.

Polyvinyl Alcohol Grade 49-88
PVOH Solution PreparationPolyvinyl Alcohol Grade 49-88 is a high-viscosity (49 cps for a 4% solution) and partially hydrolyzed (88%) water-soluble polymer. Equivalent to PVOH5042, Elvanol® 50-42, SELVOL 540, and POVAL 49-88, it dissolves in cold water but benefits from heating or warm water for complete dissolution. This polymer offers high tensile strength, tear resistance, and excellent properties as a disperser and stabilizer. Applications include stabilizing vinyl acetate, polystyrene, and polyvinyl chloride emulsions, re-moisturizing adhesives, temporary binders for ceramics, water-soluble films, paper adhesives, photosensitive coatings, and as a soil anti-redeposition agent. PVOH 49-88 is also widely used in personal care, construction, textile, and emulsion industries and is a key ingredient for making slime.
Product Specifications
| Viscosity (4% Solution) | 47–49 cps |
| Hydrolysis Level | 88% (partially hydrolyzed) |
| Solubility | Cold-water soluble (heating recommended for complete dissolution) |
| Equivalent Products | PVOH5042, Elvanol® 50-42, SELVOL 540, Poval 49-88 |
| Applications | Emulsions, adhesives, coatings, paper, ceramics |
Applications and Benefits:
- Stabilization of vinyl acetate, polystyrene, and PVC emulsions
- Binder for adhesives and paper coatings
- Temporary binder for ceramics
- Water-soluble films and photosensitive coatings
- Soil anti-redeposition agent
- Key ingredient for slime making
Caution:
Handle in accordance with recommended safety procedures. Refer to the Safety Data Sheet for detailed handling and storage guidelines.
