This clearly shows that a PAO base oil substitution can significantly lower operating temperatures of the gear box and extend the required maintenance interval. application/pdf 0000010623 00000 n You see, PAOs are carefully designed, not refined. A relatively simple test, the criteria of the test varies depending on which grease manufacturer you are dealing with. A grease formulated with Synfluid PAO and OMGs Calciplex grease precursor could yield a multipurpose product, which allows for consolidation of your grease inventory. High temperatures can thin and break down oil, crippling its lubricating ability, whereas low temperatures can rob a lubricant of its ability to reach critical parts. Specific tests such as the Volkswagen T-4, TDI and Peugeot TU-5 have increased the demand for higher-quality base oils. Compatibility testing is the best option. 0000001726 00000 n 0000140275 00000 n The relationship between antioxidants (A.O.) MOLYKOTE. 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. <>stream In addition to these advantages, kosher certification for Synfluid PAOs is available upon request. Polyphenols and Foods That Are Good Sources for Them - Verywell Fit However, unlike foaming, entrained air can be a difficult problem to treat with additives. Better heat transfer coefficients, increased lubricity and the basic chemical structure of PAOs all contribute to the lower temperature in the gearbox. endobj and PAO plays an integral part of meeting the challenge for top-tier oils. guide for chemical uses The chart differentiates the blending capabilities of various base oils to meet energy-efficient motor oils. As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. Sometimes, one plus one can equal more than two. 0000016208 00000 n And we pioneered and patented our unique C12-based PAOs in the 1990s. Chevron Phillips Chemical offers two lines of PAOs. But wait, it gets even better! As the viscosity grade decreases, the volatility and high-temperature/high-shear viscosity will be limiting factors. 101 0 obj According to the U.S. government, biobased is defined as at least 44% biobased carbon content for hydraulic fluids. The information listed in parentheses is D-1418 nomencalture, common acronyms or common trade names. This process creates a polymer backbone where oxygen is every third atom, which gives PAG basestocks their distinctive chemical attributes and allows formulators to synthesize various combinations of starters and monomers (block, random, and homopolymer) to create custom basestock types for specific applications. Engine oil tests such as VW T-4 and Seq. Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. The first step is the synthesis of oligomers (polymers with few repeating monomer units) from the linear alpha-olefin. PAOs help to balance the protection and energy conservation requirements in equipment because they are more Newtonian than mineral oils. 0000022832 00000 n 3.0 CHEMICAL COMPATIBILITY GUIDE FOR METALLIC MATERIALS In addition to this chemical compatibility chart, report TR-60C, Bal Seal has two other reports: report TR-60A "Chemical Compatibility Guide for Bal Seal PTFE, Filled PTFE, and Polyethylene Seal The plot below shows a comparison of the air release times exhibited by ISO VG 320 blends composed of our Synfluid mPAOs, and traditional HV PAOs with PAO 8 cSt. With regard to performance, PAOs are able to maintain excellent thermal and oxidative stability as well as the low-temperature benefits they are known for. 0000031839 00000 n This resistance to fire and flame propagation improves the margin of safety in the event of a hydraulic leak. Challenges like these truly reveal the performance advantages of Synfluid PAOs. Both the foam tendency (the initial amount of foam generated in this test) and the time required for the foam to collapse are remarkably better for Synfluid mPAO. endobj H|% `\ml emt8uHJs;7W*"_?~o~O? Using the same PAO, we achieved 15 percent higher oxidative stability by increasing the A.O. The ability of a lubricant to reach critical metal-to-metal interfaces in a gear system can be the difference between operation or shutdown. To improve fuel economy, OEMs are moving toward lower-viscosity oils, even in heavy-duty diesel engines. There are many advantages! After all, the reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. A product developed by Renewable Lubricants Inc. (RLI), with assistance from Chevron Phillips Chemical, uses Synfluid PAOs combined with biobased oils and specially designed additives. However, nothing is perfect, and polyalphaolefin base oils do have a few negative characteristics. Sorry, you need to enable JavaScript to visit this website. 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. The superior low-temperature flow characteristics of PAOs ensure faster coating of critical parts in the compressor during startup, minimizing wear. 0000162168 00000 n Each lubricant type will be the best choice for different sets of use parameters, including: PAO-based lubricants may be preferred when the following lubricant attributes are targeted: PAG-based lubricants may be preferred when the following lubricant attributes are targeted: If end-users are in doubt about which lubricant would best suit their needs, it is recommended that an expert be contacted to assist with the decision-making process. Copyright 2023 Chevron Phillips Chemical Company LLC. 2014-03-26T09:12:57.905-05:00 Sorry, we couldn't find anything that matched your search, PAO-based lubricants generally resist creep and water washout and offer good lubricity across a variety of substrate material pairings, including metal-to-metal and metal-to-plastic. These excellent pour points are achieved while increasing the viscosity indices (VI) over traditional HV PAO. The choice of C10- or C12-derived PAO depends on the application and/or specification requirements. However, not all synthetic lubricants are created equal. This lowers their volatility, creates less hydrocarbon tailpipe emissions and raises the flash point. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. PAOs offer exceptionally low volatility due to their controlled formation, which yields carefully designed molecular weights. Sustained operations at elevated temperatures increase the rate of oxidation and other degradation reactions. !DOaBADOaB&=&=U!z During 2011, Chevron Phillips Chemical acquired PAO assets in Beringen, Belgium, and began mPAO production in Texas. 0000048689 00000 n PDF Chemical Compatibility Guide - Graco If you are using multiple greases, there are certain risks for misapplication, which are minimized with a multi-purpose grease. The key to unlocking the full potential of your formulation requires using the right combination and concentration of antioxidant and Synfluid PAO. Working in conjunction with the Union Carbide Chemicals, Plastics Company Inc., and the Mellon Institute of Industrial Research, the USNRL developed the first water-glycol, PAG-thickened, fire-resistant hydraulic fluid (WGHF).

Adding a PPD will reduce the pour point of a mineral oil, but it still will not achieve the performance of a PAO. Based on recent average gas prices, conserving just 1% to 2% of the U.S. fuel consumption per year would save $14 million per day. PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. 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. Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene. These include the tendency to shrink seals and trouble dissolving common oil additives. The rotary bomb bench test is a strong predictor of how base oils will perform in many automotive and industrial applications. Unlike other industrial basestocks, PAOs are generally classified by their kinematic viscosity at 100C. 0000134768 00000 n Changes in low-temperature viscometrics and oxidative stability requirements demand higher-quality base oils. Understanding the advantages and disadvantages of each can help end-users decide which option is best for a given application. 0000034554 00000 n Our C12-based grades further improve flash/fire points by as much as 10 percent over other commercial polyalphaolefins.
