摘要： A magnetorheological (MR) fluid comprising a glycol-based carrier fluid, a magnetizeable particle, and an inorganic clay. The MR fluid is particularly suitable for use in devices that have materials incompatible with typical hydrocarbon-based MR fluids, for example in devices where natural rubber is in contact with the fluids as in automotive engine mounts. The fluid is substantially non-foaming, and an improvement over glycol fluids thickened with organoclays.
