The term synthetic hydrocarbon (SHC) is a general term. 0000021835 00000 n Adobe InDesign CS6 (Macintosh) One way to achieve a higher VI base fluid is to shift from a decene-based PAO to a dodecene-based PAO. Polyalkylene glycol (PAG) and polyalphaolefin (PAO) are two synthetic lubricant options for industrial applications. Benefits of the new system are a much higher viscosity index (VI), superior pour points and improved low-temperature fluidity, all of which contribute to improved energy efficiency. Some properties such as Viscosity Index (VI) or C viscosity can approach those of PAOs. While pour point is one consideration, a formulator has to take into account the total specification needs. A similar approach can be applied to your formulations or applications. In addition to meeting current limits, a lower viscosity will reduce energy consumption. The more EO monomer in the basestock, the more water-soluble; the more PO monomer, the more water-insoluble; and the more BO monomer, the more oil-soluble the basestock is. The chart below shows specific properties of four of our PAO grades that are well-suited to metalworking applications. In the chart below, we highlight how moving from a decene-based Synfluid PAO 6 to an iso-viscous dodecene-based fluid (resulting from a blend of PAO 5 and PAO 7) leads to a dramatic increase in VI. 0000034554 00000 n At that time, both fires on U.S. Navy ships and aircraft were occurring due to the use of mineral oil-based hydraulic fluids. 175 0 obj The first step is the synthesis of oligomers (polymers with few repeating monomer units) from the linear alpha-olefin. %PDF-1.5 % Furthermore, PAOs are H-1 approved for incidental food contact and have good organoleptic properties, which broaden the range of end-use applications for metals. To mitigate this effect, We recommend taking a look at Synfluid PAO 5 and PAO 7, due to their excellent Noack volatilities of 5.5% and 2.3%, respectively. There are many advantages! 97 0 obj We make the petrochemical solutions found in products of all kinds with purpose, collaboration and care. Because PAOs have a diverse, highly branched isoparaffin structure, they provide excellent low-temperature viscometrics and very low pour points (ppt) without adding PPDs. The chart below shows the gas chromatogram of PAO versus white mineral oil, illustrating the relative enhanced purity of PAO. For example, the fraction that has predominantly the 1-decene trimer (C30 oligomer) has a 100C viscosity of 4 cSt and is known as PAO 4. Great question! As an example of the improved low-temperature torque properties of the PAO-based grease, the chart below shows torque values for Chemtools CSC 980 grease under ASTM D 4693 test conditions for rotation of a wheel-bearing assembly at -40C.
