Process Chemical Compatibility Guide Galvanized steel is susceptible to attack by some chemicals which may cause . You see, PAOs are carefully designed, not refined. As the chart above clearly demonstrates, the difference in viscosity as a function of shear rate is magnified as temperature decreases. Why does this happen? One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. 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. For other applications, PAOs safe and non-toxic nature allows them to be used where incidental food contact certification or kosher approval is necessary. While viscosity improvers can enhance VI, they can break down over time, resulting in diminished performance.

For instance, a 100 percent aminic antioxidant package will yield the best performance in the Rbot test for PAO. The most favorable performance is achieved by using the highest-quality base oils. PAO-based greases are typically used at temperatures over 100C because of thermal and oxidative concerns. Both basestock types have low volatility and high fire points (when stabilized) for a given viscosity grade. The reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. We make the petrochemical solutions found in products of all kinds with purpose, collaboration and care. PAO-based lubricants offer a significant advantage in oxidative stability. The remaining synthetic lubricants are produced from other basestocks, including phosphate esters, polybutenes, silicones, perfluoroalkyl, and polyphenyl ethers. Low-viscosity Synfluid PAOs are both NSF H1 and HX-1 registered. Conversely, if you reduce the temperature, the reaction rate decreases and the oil lasts longer, providing better protection. The chart below shows the trends in industry specifications regarding low-temperature performance relative to Synfluid PAO. In the past three years, European specifications for volatility and oxidative stability have become significantly more stringent. When possible, testing compatibility between the specific PAG lubricant to be used and the specific seal types or paints to be used is recommended. The chart below shows biodegradation test results for Synfluid PAO 2.5, 4 and C12 Dimer, which indicate that these products could qualify as inherently biodegradable according to the ASTM D5864 test method. The degree of the advantage may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). As the chart above shows, lower-viscosity oils can be made without sacrificing low volatility by using PAO base oils. BioPreferred is a registered service mark of the United States Department of Agriculture. It is really the formulators preference whether to increase the longevity of a vehicles moving parts, haul a heavier load, or save money at the fuel pump. In contrast, the Synfluid PAO formulation achieves a pass with as little as 30 percent PAO, the balance being Group I mineral oil. This new system improves the viscosity properties, which should be more energy conserving and achieves the ultimate biodegradation rating ASTM D5864-PW1. In these extreme services, a PAO-based lubricant is able to reach the area that requires lubrication and prevent damage or wear. Lack of mineral oil solubility is a barrier to expanded use of PAG-based lubricants. The results indicate that the CSC 980 Tan grease has a running torque of 3.77 N-m versus 10.9 N-m for the same grease with an alternate base oil. The trend falls short when comparisons are made between PAOs and mineral oils, based solely on the VI. what chemicals to use The direct feedstock (normal alpha olefin NAO) is produced through the chain growth and displacement process for producing petrochemically pure alpha olefins. As a result, the jump in the viscosity adversely effects the ability to pump at low temperatures. 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.
