Hydraulic fluid shear stability
Find out how hydraulic fluids maintain optimum viscosity in a wide range of operating conditions and temperatures.
Hydraulic fluids must maintain good pumpability at low temperatures and sufficient film strength at high temperatures. The following research examines the viscosity-temperature relationship, the impact of viscosity index improvers at different temperatures and the importance of using a shear stable hydraulic fluid.
