Medium-viscosity, fully hydrolyzed polyvinyl alcohol with excellent film properties.
High-viscosity, partially hydrolyzed polyvinyl alcohol for diverse applications.
Polyvinyl Alcohol 30-99, Elvanol 71-30
PVOH Solution PreparationPVOH 30-99 (Elvanol® 71-30) is a medium-viscosity, fully hydrolyzed polyvinyl alcohol designed for applications requiring high tensile strength, tear resistance, and excellent adhesion to hydrophilic surfaces. This white granular polymer is soluble in hot water and forms transparent films upon evaporation. Insoluble in cold water and common organic solvents, PVOH 30-99 is widely used in the paper, textile, ceramic, and adhesive industries. Key applications include sizing for paper and textiles, ceramic fiber binder, and wallpaper glue. PVOH 30-99 offers excellent film-forming characteristics with superior resistance to tearing and high strength, making it a versatile polymer for coatings, adhesives, and emulsions. It is often applied using brushes, rollers, or spray equipment.

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 |
