๐งช Carbopol Ultrez 21 in propylene glycol, flow curve (community)๏
dataset id: caggioni_pg_carbopol_2pct
A single equilibrium flow sweep of 2% Carbopol Ultrez 21 dispersed in propylene glycol: 61 points from 10^-3 to 10^3 s^-1 at 20 C, measured with a concentric-cylinder geometry. Carbopol is a jammed microgel (a soft-particle glass) and propylene glycol is a viscous continuous phase; this combination is the textbook case where a three-component (TC) model separates the particle and viscous contributions better than Herschel-Bulkley. Originally measured for the rheofit fit-app walkthrough.
