- A category of base stocks with an alkyl subcategory typically used in aircraft hydraulic fluids, and an aryl subcategory typically used in compressor oils, metal production/mining hydraulic fluids, steam and gas turbine power generation. phosphate esters offer low volatility, good chemical stability and fire resistance/good fire-extinguishing capabilities. they are sensitive to moisture and high density, and they have selective seal and paint compatibility. they can be considered toxic/hazardous in large quantities.
