Recommended Mixing Equipment For Polyvinyl Alcohol Solutions

Polyvinyl alcohol (PVOH, also referred to as PVA) is a versatile polymer that plays multiple roles in the manufacture of adhesives, sealants, cosmetics, paper, textiles and many other products.

Various grades of PVOH are available in powder form which needs to be dissolved in water. For this task, conventional stirrers and propellers often prove inefficient, especially in large volumes, because PVOH powders can tend to float and form lumps that take a long time to dissolve completely.

This paper describes the benefits of preparing PVOH solutions in a well-designed Multi-Shaft Mixer capable of bulk agitation, high shear deagglomeration, and superior heat transfer.
