WebPolymer powders are produced by spray-drying polymer dispersions. In contact with water, the dispersible polymer powder grains disintegrate and release the individual dispersion particles again. The dispersed polymer powder has the same properties as the original dispersion. Polymer powders were first produced in WACKER laboratories in 1957.
