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.

- PVA 217
- Elvanol® 52-22
Polyvinyl Alcohol Grade 25-88
PVOH2588 is a medium-viscosity (25 cps), partially hydrolyzed (88%) water-soluble polymer that dissolves in warm or room-temperature water. Equivalent to Elvanol® 52-22, Poval 26-88, Poval 22-88, Selvol 523, and PVA-217, this polymer is widely used in coatings, adhesives, and films. It is especially valued for its higher binding capacity compared to synthetic latex and starch, making it ideal for spiral wound tubes, coated paper, linerboard, and specialty water-soluble films. PVOH2588 also adds strength to recycled boards and enhances oil and grease resistance.
Additional applications include stabilizing vinyl acetate, polystyrene, and polyvinyl chloride emulsions, re-moisturizing adhesives, temporary binders for ceramics, photosensitive coatings, and as a soil anti-redeposition agent. It is suitable for use in textile coatings and joint compounds.
