Abstract
Magnetorheological fluid compositions that include a carrier fluid, magnetic-responsive particles and an organoclay. These fluids exhibit superior soft sedimentation.
Claims9
A magnetorheological material comprising a carrier fluid;
- magnetic-responsive particles having average diameters of 0.10 to 1000 μm;
- and a hydrophobic organoclay derived from a bentonite, wherein the magnetorheological material has sediment layer hardness value of less than 3.0 N.
