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. False 0 There are several systems where we have observed a reduction in the operating temperature compared to mineral oils, including transmissions, engines and heat transfer applications. The difference in the CCS viscosity at -35C is 15 percent, which is substantial. Since then, the company has expanded PAO as well as ethylene production, both basic building blocks for many petrochemical processes. 97 0 obj Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants. 0 The reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. At that time, both fires on U.S. Navy ships and aircraft were occurring due to the use of mineral oil-based hydraulic fluids. The VI of Synfluid mPAO 40 and 100 cSt is 170 and 194, respectively. 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. CHEMICAL RESISTANCE CHART. The dodecene-based products offer lower volatility at comparable viscosities to the decene-based products. The information listed in parentheses is D-1418 nomencalture, common acronyms or common trade names. The use of mineral oil-based lubricants in the world, however, is decreasing. As temperature decreases, a higher VI fluid will have reduced viscous drag, which could lead to higher horsepower and energy efficiency. You bet! Engine oil tests such as VW T-4 and Seq. Reducing the viscosity of engine and drivetrain oils lowers fuel consumption by decreased churning losses and viscous drag. Disadvantages of PAG-based lubricants are summarized in Table 3. The limits on lowering the viscosity grade are tied to the base oil properties. 2013-07-10T14:05:23-05:00 The challenge presented to a formulator is maintaining the performance levels while achieving biodegradability.

Understanding the advantages and disadvantages of each can help end-users decide which option is best for a given application. You would expect the viscosity to improve with a lower pour point, but the opposite is true. 0000103071 00000 n PAG- and PAO-based lubricants rarely compete in industrial applications. Defense Daily subscriber and registered users, please log in here to access the content. 0000000016 00000 n Challenges like these truly reveal the performance advantages of Synfluid PAOs. These 1-dodecene-based products (Synfluid 2.5, 5, 7 and 9cSt PAOs) are now recognized to have superior performance in their own applications. The rotary bomb bench test is a strong predictor of how base oils will perform in many automotive and industrial applications. Chevron Phillips Chemicals PAO history dates back to December 1980, when the continuous PAO unit at Cedar Bayou, Texas, started up with heritage Gulf Oil, which Chevron Chemical subsequently acquired in 1985. In both cases, the reduction in volatility will translate to lower oil consumption and reduced engine varnish over the life of the oil. III F challenge formulators, and their suppliers, to step up performance for the next generation of engine oils. %PDF-1.4 % As oil volatilizes, the viscosity increase will result in poorer overall performance. Some of the disadvantages of PAO-based lubricants are outlined in Table 6. Absolutely! PPDs act only on linear or waxy compounds, and these characteristics are absent from PAOs. Lowering torque reduces the energy requirements of the equipment and improves grease distribution. These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile. Give us a call, and well be happy to discuss our high-quality Synfluid PAOs with you. Jun 09, 2022. polyalphaolefin compatibility chart . 95 0 obj The most favorable performance is achieved by using the highest-quality base oils. 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. To improve fuel economy, OEMs are moving toward lower-viscosity oils, even in heavy-duty diesel engines. endstream endobj 8 0 obj <>stream 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. Available on demand until February 16, 2024. However, not all synthetic lubricants are created equal. They're found in everyday food and available as supplements. To get a superior lubricant, you need to start with a superior base oil. There are emerging markets that demand the improved VI and volatility that only the C12-based PAOs can deliver. <> 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. 0000036005 00000 n 0000034554 00000 n According to the U.S. government, biobased is defined as at least 44% biobased carbon content for hydraulic fluids. !DOaBADOaB&=&=U!z The information from such third party sources is believed to be reliable and accurate; however, Purchaser should make its own determination of compatibility before using any SpillTech product. hb```b``nd`c``. Finally, due to their excellent response to antioxidants, Spectra-Syn Plus PAO can be formulated to resist thermal oxidative attack. 0000161810 00000 n The viscosity of the base oil is largely irrelevant in relation to the compatibility risks with the thickener. polyalphaolefin compatibility chart. 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. For other applications, PAOs safe and non-toxic nature allows it to be used where incidental food contact certification or kosher approval is necessary. Oxidative stability is a critical property enabling oils to resist sludge formation and degradation while in service. 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. In our experience, some commercially available additive packages are designed to take better advantage of a specific base stock. 0000162168 00000 n PAO fluids are classified as a Group IV base oil and are made by a two-step reaction process using linear alpha-olefins like 1-decene. PAO- and PAG-based lubricants are both hydrolytically stable and have low pour points. Applications for PAO-based lubricants expanded to circulating and gear oils. Ethylene is produced by cracking either crude oil or natural gas. By utilizing this new process combined with the inherent properties of PAOs, a grease can be produced that can be used in both extreme high- and low-temperature applications. The chart below shows a comparison of the foaming characteristics of our Synfluid mPAO high-viscosity base oils with traditional high-viscosity PAO 40 and 100 cSt base oils. As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. In drivetrain lubricants, reducing the traction coefficient and lowering viscosity are key ways to increase fuel economy, but lower viscosity must be balanced to provide adequate wear resistance. The properties mentioned above are in addition to the normally excellent performance you have come to recognize with PAO. concentration from 0.5 percent to 1 percent. Thats a hot topic! %%EOF Youre not kidding! In order of volume used, they are: polyalphaolefins (PAOs), organic esters, and polyglycols. Process Chemical Compatibility Guide 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. We make the petrochemical solutions found in products of all kinds with purpose, collaboration and care. Other base oil properties need to be considered. The remaining synthetic lubricants are produced from other basestocks, including phosphate esters, polybutenes, silicones, perfluoroalkyl, and polyphenyl ethers. 0000052609 00000 n 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. 0000004968 00000 n Let us help you.
