👉 The Hansen fluid, also known as Hansen's oil or Hansen's viscous fluid, is a high-viscosity, non-Newtonian fluid developed by the German chemist and engineer Hansen in the early 20th century. It is primarily composed of mineral oils and additives, designed to exhibit shear-thinning properties, meaning its viscosity decreases under applied stress or shear, making it ideal for lubrication applications. In high-pressure scenarios, such as hydraulic systems, the Hansen fluid maintains its viscosity and provides excellent lubrication and wear protection. Its unique characteristics make it particularly useful in heavy-duty machinery, where consistent performance under extreme conditions is crucial.
