However, Synfluid PAOs can be formulated to be biodegradable and are well known for standing out from conventional base oils. Glad you asked! The degree of the advantage may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). 165 0 obj Approximately 80% of synthetic lubricants used in the world are of three types. 0000001605 00000 n Polyalkylene glycol (PAG) and polyalphaolefin (PAO) are two synthetic lubricant options for industrial applications. Our team of experts answer the most frequently asked questions. PAOs offer exceptionally low volatility due to their controlled formation, which yields carefully designed molecular weights. Reducing the viscosity of engine and drivetrain oils lowers fuel consumption by decreased churning losses and viscous drag. Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene. Low-viscosity PAO fluids are used in automotive applications, such as engine oil and gear lubricants. The Scanning Brookfield chart on this page demonstrates the difference in viscometrics between a Synfluid PAO and a pour point depressed mineral oil. They're found in everyday food and available as supplements. Synfluid mPAOs exhibit faster air release times, particularly when comparing the 100 cSt blends. According to analysis conducted by Kline & Co., more than 78% of all lubricant requirements in the world annually are met with the use of mineral oil-based fluids. If you are using multiple greases, there are certain risks for misapplication, which are minimized with a multi-purpose grease. They are also employed as base fluids in some wide temperature range greases. Chevron Phillips Chemical offers two lines of PAOs. More uniform in structure than conventional PAO basestocks, they provide similar advantages of high viscosity indices, excellent low-temperature fluidity, and shear stability but with additional thickening ability. A formulator choosing the right base oil is like a craftsman choosing the right tool it needs to fit the job. material chemical compatibility Heavier components adversely affect low-temperature performance and pour point. Although VI is an important indicator, when used alone, VI is misleading. Volatility is a concern for many applications, especially where higher operating temperatures occur or longer service life is desired. The PAOsare produced through synthesizing oligomers of either 1-decene or 1-dodecene. The chart below shows the gas chromatogram of PAO versus white mineral oil, illustrating the relative enhanced purity of PAO. General properties of water-soluble, water-insoluble, and oil-soluble PAG basestocks are shown in Table 1. The benefit of a lubricant to the end user is an important question, and the behavior of a base oil is only one of many variables affecting the performance of a finished formulation. While one lot of Group IIIA mineral oil passed this battery of tests, it is quite different from the quality of the other Group III stocks. Give us a call. It is true there are many high-quality base oils around, but the highest quality is still achieved when Synfluid PAOs are chosen. <> Both the foam tendency (the initial amount of foam generated in this test) and the time required for the foam to collapse are remarkably better for Synfluid mPAO.
