High shear thickener
WebProduct Technologies Offers low, mid, and high shear solutions adaptable to changing shear rates while supporting specific formulation goals. ACRYSOL™ HASE and HEUR Rheology Modifers deliver specific benefits individually and, when used in combination, can facilitate unique performance properties that neither chemistry family can provide alone. WebJul 6, 2024 · High shear mixers, characterized by a rotor/stator mixing head, are widely used for wetting out thickeners and preparing a fine dispersion. The classic design is characterized by a four-blade rotor running at tip speeds in the range of 3,000-4,000 ft/min within a close tolerance fixed stator.
