""2(! Specific tests such as the Volkswagen T-4, TDI and Peugeot TU-5 have increased the demand for higher-quality base oils. endobj PAO-based rotary screw compressor oil offers better performance in the compressor. Consistent feedstocks give rise to consistent PAO quality, resulting in consistent finished fluid performance. Whichever low-viscosity base oil is used, it must exhibit viscosity stability and low volatility. What is most interesting, however, is the low-temperature performance: The C10-based PAO 6 has the lowest pour point by over 20C, but the CCS viscosity for the C12-based PAO 5 and 7 blend is better. The second step is the hydrogenation of the remaining double bonds (unsaturation) in the oligomer and subsequent distillation to separate the unreacted monomer and light-viscosity grade PAO. We are first in your inbox with the most important news in the industry―keeping you smarter and one-step ahead in this ever-changing and competitive market. Adobe PDF Library 10.0.1 European specifications, as well as those in other regions, are expected to tighten. We have measured a 25 percent improvement in oxidation induction times simply by decreasing the test temperature by 10 degrees. The differences in flash, fire, volatility and viscosity highlight the flexibility benefits of using a Synfluid PAO. After the formation of the Chevron Phillips Chemical joint venture in 2000, a 10 KTA PAO unit expansion followed soon thereafter. The current trend toward lower viscosities, while providing for extended drain capabilities, does present an interesting challenge for base oils. However, unlike foaming, entrained air can be a difficult problem to treat with additives. Both lubricant types are used in industrial gearboxes, compressors, and even air conditioning systems.

The primary difference between these two products is pour point. We believe that it is possible to achieve a passing mark with even lower amounts of PAO, further reducing costs. PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. This property coupled with excellent oxidative stability provides a formidable component in an engine oil formulators toolbox. Polyalphaolefins also have poor fire resistance and biodegradability. Since this can be achieved without sacrificing hydrolytic stability, the finished lubricant will maintain superior properties over an extended period of time, resulting in less waste. 0000035588 00000 n
C12-derived PAOs also provide advantages with higher Viscosity Index (VI), better flash/fire points, and even lower cold crank simulated viscosities. Chevron Phillips Chemicals Synfluid mPAO 65, 100 and 150 cSt products have very high viscosity indices and lower pour points than other HV PAO products. Each 10C temperature rise can reduce oxidative stability by half. This will increase the dependence on high-quality base oils such as PAOs. In a comparison of gear lubricants, PAOs reduced the effective operating temperature by as much as 10 20C.

The degree of the disadvantage for seal and paint compatibility may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). High-viscosity PAO fluids have also become popular in industrial fluids and greases. The price of Polyalphaolefin (PAO) has been steadily decreasing throughout the third quarter of 2022 on the back of the poor performance of the downstream automotive sector in the continent. polyalphaolefin compatibility chart. 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. Lowering torque reduces the energy requirements of the equipment and improves grease distribution. Because of their controlled structure, PAOs do not contain lighter, more volatile (small) hydrocarbons. However, Group III base stocks are derived from multiple feedstock choices and processing technologies, which create variability in the properties. 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. However, these products have demonstrated unique advantages in Sequence IIIF, VW T4 and TDI tests due to many of the other properties that are inherent in them. These requirements or specifications will generally identify or recommend a product type (mineral oils, synthetic fluids, or bio-based fluids) and the proper performance requirements (developed into the lubricant by the component chemistry) to allow the machinery to run at an optimum level.
