SYNTHETIC FIRE-RESISTANT HYDRAULIC FLUIDS FOR GENERAL INDUSTRIAL USE.

Tests of fire resistance, stability and lubrication properties were carried out to determine how the performance of the new carboxylate esters matches that of the established triaryl phosphates. A comparison of the properties of the established synthetic triaryl phosphate ester hydraulic fluids with the more recently introduced oleate esters showed that the oleate esters are more fire-resistant than mineral oils, but considerably less fire-resistant than the synthetic triaryl phosphate esters.
