Description of key information

WP30 partcle size is in the range of 1.5 µm - 150 µm, and its profile is a bimodal curve.

Additional information

WP30 particle size has been measured with a Malvern mastersizer Hydro 2000S. For particle size measurement, a slurry of WP30 in water was prepared with addition of surfactant. Average of 3 measurements gave:

D10 = 15.2 µm

D50 = 38.2 µm

D90 = 86.1 µm
