Polyvinyl Alcohol (PVA, sometimes referred to as PVOH) is a water soluble polymer used widely in adhesives, paints, sealants, coatings, textiles and plastics, etc.
This should not be confused with Polyvinyl Acetate, also known as PVA.
The powder is readily soluble in water, but as the water temperature is increased the powder begins to swell and become sticky which causes agglomerates in the mix.
With a Silverson mixer you can disperse PVA into hot water, adding the powder as rapidly as the machine will take it in - a massive saving in processing time.
The Silverson mixer is able to finely disperse the powder ensuring rapid solubilisation and an agglomerate-free mix.
