As temperature increases, a higher VI fluid will give increased fluid film thickness, which could result in lower wear. xmp.did:F87F1174072068118083E936383AAE83 <> PAO-based greases are typically used at temperatures over 100C because of thermal and oxidative concerns. The table below shows a comparison of conventional hydraulic oils with the new PAO biobased lubricant from RLI. However, not all synthetic lubricants are created equal. The current trend toward lower viscosities, while providing for extended drain capabilities, does present an interesting challenge for base oils. For instance, Chemtool Incorporated utilizes Synfluid PAOs in greases, and they have been able to formulate their products to take specific advantage of Synfluid PAO properties, yielding improvements in low-temperature mobility and torque. Initially, it was intended to fill the gap in supply and was found to be exceptionally suitable for applications where extremely low pour points were not necessary. Grease is a solid to semi-fluid lubricant, typically used for difficult to service equipment, such as bearings or suspension systems. Although PAOs are not considered biobased themselves, in a blend they contribute certain performance benefits. As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. Finally, due to their excellent response to antioxidants, Spectra-Syn Plus PAO can be formulated to resist thermal oxidative attack. Two lubricants with the same VI may perform dramatically differently at low temperatures. Rotary screw compressor oils formulated with PAO offer performance benefits not obtainable with a mineral-oil-based formulation. 0000135019 00000 n Our C10-based products, commercialized in the 1970s, were the first in the market. The effects of the shear rate differences are even more exaggerated at low-temperature startup conditions, when the lubricant function is critical for equipment protection. Oxidative and other lubricant degradation mechanisms would follow the same trend. Synfluid PAOs have been carefully designed to yield oxidative induction times greater than 2,500 minutes with 0.5 percent antioxidant. This same technology can also be beneficial for biobased gear lubricants, chain and cable lubricants/greases, and other applications for equipment used in sensitive environmental areas. Absolutely! PAO-based rotary screw compressor oil offers better performance in the compressor. C 20 40 60 20 40 60 80 100 20 40 60 80 100 20 40 60 80 100 120 20 40 60 . 0000034554 00000 n Were here to help. Well be happy to help you solve your lubricant concerns. Furthermore, the arbitrary distinction of 120 VI between Group II and III oils makes the quality requirements even more confusing. As the chart above shows, lower-viscosity oils can be made without sacrificing low volatility by using PAO base oils. 176 0 obj A solution, developed by Renewable Lubricants Inc.

Polyalphaolefin Characteristics 102 0 obj <> (2;2222;;;;;;;;;;;;;;;;;@@@@@;@@@@@@@@@@@@@@@@@@@@@ " B 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. The qualitative chart below describes the impact of each grease component on certain performance characteristics: Clearly, the base oil dominates some grease properties, while the additives or thickener drives others. This resistance to fire and flame propagation improves the margin of safety in the event of a hydraulic leak. Blending lower-quality base oils into this formulation would compromise the passing mark. 0000000724 00000 n As temperature decreases, a higher VI fluid will have reduced viscous drag, which could lead to higher horsepower and energy efficiency. Lowering torque reduces the energy requirements of the equipment and improves grease distribution. 10.1 Introduction. 0000135615 00000 n These 1-dodecene-based products (Synfluid 2.5, 5, 7 and 9cSt PAOs) are now recognized to have superior performance in their own applications. 179 0 obj One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. The chart below shows rotary bomb (ASTM D2272) results between Synfluid PAOs and some mineral oils. Refined mineral oils often contain sulfurs, aromatics and other compounds that can erode the quality and consistency of a mineral oil. The most favorable performance is achieved by using the highest-quality base oils. 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. In terms of viscosity, there are tradeoffs in choosing one PAO over another: energy consumption (heat dissipation and production throughput) versus safety of operations (impacted by flash/fire points and volatility). The direct feedstock (normal alpha olefin - NAO) is produced through the chain growth and displacement process for producing petrochemically pure alpha olefins. In contrast, the Synfluid PAO formulation achieves a pass with as little as 30 percent PAO, the balance being Group I mineral oil. Furthermore, thermal conductivity at 300F for PAO 6 is 0.085 compared to 0.071 Btuft/(hft2F) for an equiviscous mineral oil, which means that the PAO can conduct 20percent more heat than the mineral oil for better heat dissipation. 4 Chemicals PVC CPVC PP PVDF ABS. Driveline specifications continue to become more stringent. Some properties such as Viscosity Index (VI) or C viscosity can approach those of PAOs. endobj PAO basestocks using conventional catalysts are commercially produced in five low-viscosity grades and two high-viscosity grades to a maximum viscosity of 100 centistokes (cSt) at 100C. They are usually derived from a small set of simple olefins ( alkenes ). endobj 0000048689 00000 n Compatible with seals and paint used with mineral oil, no need for change at all operating temperatures. Since there are no other discernable compounds, Synfluid PAOs are more readily biodegradable and can be used for some food applications. These include the tendency to shrink seals and trouble dissolving common oil additives. The superior benefits of PAOs enable formulators to meet these challenges. A Group III mineral oil with a 0.1 percent PPD achieves an improved pour point, but to the detriment of the low-temperature viscometrics. 0000000995 00000 n Polyolefin. hak1YmPaZI>BYzW+d~2^!dVQ ," #@^Ht 9@}VNJ ,kmLrVT U$^H-1' fMH]T U #5o=EmWae4/nW7fg9on_~mSPI_L7borVsezS[uWdg[]]>oo.o7t|xsMU/ojy4i_[u;cJ~Oz5wj1S5"b!CBd2$U3@Rb'EsHd*DzHWcucC=d8tl=d8,trSdx}=dXY>BR>!GB=dph\Wg0?0. <>stream The vast number of high-quality base oil choices can be confusing when balancing fuel efficiency and wear protection. 9 0 obj <>stream Low-temperature fluidity and high-temperature thermal and oxidative stability are key factors for choosing a PAO.

Polyalkylene glycol (PAG) and polyalphaolefin (PAO) are two synthetic lubricant options for industrial applications. Having a high viscosity index helps to protect an engine at temperature extremes. endstream The chart below shows the trends in industry specifications regarding low-temperature performance relative to Synfluid PAO. 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. PAG-based lubricants are polar (water-soluble PAG > water-insoluble PAG > oil-soluble PAG), where PAO-based lubricants are essentially non-polar. In these extreme services, a PAO-based lubricant is able to reach the area that requires lubrication and prevent damage or wear. 2 shows the flow chart for producing Cu nanolubricants. Aluminum is compatible with fluids such as polyalphaolefin (PAO), oil, ethylene glycol and water solutions (EGW), as well as Fluorinert, an electrically insulating inert perfluorocarbon fluid manufactured by 3M and used in many electronics cooling applications. 0000034812 00000 n 0000010736 00000 n 0000035588 00000 n The degree of the advantage may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). Because PAOs have a diverse, highly branched isoparaffin structure, they provide excellent low-temperature viscometrics and very low pour points (ppt) without adding PPDs. Focusing on the components of the additive package can further influence the performance of the formulation. One obvious trend is that low-viscosity oils are beneficial in improving fuel efficiency. 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. 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. cally stable, have good compatibility with mineral oils and can be combined with other more polar synthetic basestocks (e.g. PAO quality is unrivaled in the industry. As the chart above shows, lower-viscosity oils can be made without sacrificing low volatility by using PAO base oils. PAOs help meet and exceed the formulation requirements necessary in a wide variety of specifications, including Allison TES-295, Eaton PS-162 and Mil-2105. But wait, it gets even better! These advantages are achieved without the need for VI improvers or other additives, which may promote other deleterious effects as they degrade. 0000033764 00000 n 0000016208 00000 n Unlike other industrial basestocks, PAOs are generally classified by their kinematic viscosity at 100C. what chemicals to use A run through the test: The information listed in parentheses is D-1418 nomencalture, common acronyms or common trade names. Meet new original equipment manufacturer and industry standard requirements. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. endobj So, whether used for gear or engine oils, PAOs provide more consistent properties and a level of purity not available from other base oil groups. The chart below shows the gas chromatogram of PAO versus white mineral oil, illustrating the relative enhanced purity of PAO. Using the same PAO, we achieved 15 percent higher oxidative stability by increasing the A.O. More specialized polyolefins include polyisobutylene and polymethylpentene. With todays oils requiring a higher-quality lubricant basestock to meet more stringent tests, polyalphaolefins are perfectly tailored and consistently manufactured to meet the challenge. Chemical Compatibility Guide The higher the coefficient, the greater the change in viscosity at elevated pressures. application/pdf As the chart above clearly demonstrates, the difference in viscosity as a function of shear rate is magnified as temperature decreases. Although VI is an important indicator, when used alone, VI is misleading. High-viscosity PAO fluids have also become popular in industrial fluids and greases. Fluid distribution panels are also discussed. Synfluid PAOs, in addition to NSF H1 qualification, are also available as kosher approved products. 0000000776 00000 n Sorry, you need to enable JavaScript to visit this website. As oil volatilizes, the viscosity increase will result in poorer overall performance. If a certain application can sacrifice a 10 15C increase in the pour point, then there is as much as a 25% improvement in volatility, as shown in the chart below. This clearly shows that a PAO base oil substitution can significantly lower operating temperatures of the gear box and extend the required maintenance interval. 0000001211 00000 n 0000010623 00000 n The combination of air and oil can often lead to foaming issues. PAO-base oils help improve fuel economy in engine and drivetrain oils by reducing viscosity, volatility and traction coefficients as the chart below shows: These results show the potential for reducing friction loss using PAOs, which also typically have lower pressure-viscosity coefficients than mineral oils reducing elastohydrodynamic gear friction losses and energy consumption. 0000003107 00000 n 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. 4e739735ec50523ad929b6aac8340ae467185943 xmp.did:00801174072068118083E936383AAE83 Absolutely!

The chart below illustrates how Chevron Phillips Chemical has come up with an economical solution to a VW T-4 engine test. PAOs derived from 1-dodecene can improve many properties, including volatility. Synthetic lubricants can meet these demands because they perform better than mineral oil-based lubricants in many or all the critical performance areas: reduced wear and friction, resistance to sludge formation, lower volatility, greater corrosion protection, and improved thermal and oxidative stability. The 2002 U.S. Farm Bill Act mandates government agencies to purchase environmentally safe, biobased (vegetable oil) lubricants. All rights reserved. With many new base oils being introduced to the market, lubricant consistency can really be a challenge. Oxidative stability is a critical property enabling oils to resist sludge formation and degradation while in service. As the chart below shows, greater energy efficient, lower viscosity oils can be made through the selection of PAO, without sacrificing volatility. In addition to these properties, weve also seen a significant reduction in the traction coefficient as compared to conventional high-viscosity PAOs. We have found that Synfluid metallocene polyalphaolefins (mPAOs) not only have low foaming characteristics, but they also exhibit rapid air release when compared to traditional high-viscosity PAOs. 1. The chart below shows the effect of two different shear rate viscosity determinations on three different fluids (4 cSt at 100C) and the dramatic differences between them.
