Evaluation of Environmentally Acceptable Hydraulic Fluids.
Abstract
This describes the laboratory evaluation of environmentally acceptable (EA) commercial hydraulic fluids formulated with vegetable oils and synthetic esters. Evaluations included viscosity, flammability, corrosion and wear protection, thermal and oxidation stability, low temperature capability, elastomer compatibility, and storage stability. Results showed the vegetable based products were limited in operational temperature ranges (-10 deg C to 90 deg C) due to poor thermal and low temperature stabilities. On the other hand, synthetic ester based fluids showed a wide operational capability (-40 deg C to 150 deg C) which can meet the requirements of military mobile hydraulic fluids. Although EA hydraulic fluids did not meet the current military specification requirements they are potentially good candidate fluids for the replacement of some current petroleum based military hydraulic fluids. jg
