  • $16.00


PVOH2588 is a medium viscosity (25 cPs), Partially hydrolyzed (88%) plastic that can dissolve in warm or room temperature water. PVOH2588 compares to Elvanol® 52-22, Poval 26-88, Selvol 523 and PVA-217. Applications include the manufacture of spiral wound tubes, coated paper and linerboard, and specialty water-soluble films. Its higher binding capacity versus synthetic latex and starch make it attractive for use in coatings. It adds strength in recycle board and adds barrier properties for improved oil and grease resistance. It is also suggested for evaluation in the stabilization of vinyl acetate, polystyrene and polyvinyl chloride emulsions. It has additional applications in remoisturizing adhesives, temporary binder for ceramics, water-soluble film, paper adhesives, cold-water-soluble film, photosensitive coatings, binder for joint compounds and textile coatings, and as a soil anti-redeposition agent.
