However, VI doesnt tell the whole story it only reflects the viscosity/temperature relationship between 40C and 100C. There are other advantages, such as oxidative and thermal stability, which you would naturally expect from a PAO-based product. PAG lubricant basestocks can be designed to be water-soluble, water-insoluble (partial mineral oil compatibility), or oil-soluble, depending on the selection of starter molecules and monomers to be used in producing the polymer. I love to talk about food, and I love to talk about Synfluid PAO! There are indeed pressures in the industry that require improved oxidative stability. The direct feedstock (normal alpha olefin NAO) is produced through the chain growth and displacement process for producing petrochemically pure alpha olefins. xmp.iid:00801174072068118083E936383AAE83 General properties of low- and high-viscosity conventional PAO, and metallocene-catalyzed mPAO basestocks, are shown in Table 4. 0000004340 00000 n

Compatibility testing is the best option. PAOs are used extensively in automotive fluids as well as hydraulic, gear and bearing oils, working in extremely cold climates or hot applications. 179 0 obj One way to achieve a higher VI base fluid is to shift from a decene-based PAO to a dodecene-based PAO. PPDs act only on linear or waxy compounds, and these characteristics are absent from PAOs. There can be many benefits from choosing a high VI base fluid. The viscosity of the base oil is largely irrelevant in relation to the compatibility risks with the thickener. Low molecular weight compounds will degrade other performance requirements, such as volatility, flash and fire points. A process enhancement at Chevron Phillips Chemicals manufacturing facility has resulted in up to a 30 percent improvement in oxidative stability when used with aminic antioxidants in Rotary Bomb Oxidation Tests (RBOT).
