It is true there are many high-quality base oils around, but the highest quality is still achieved when Synfluid PAOs are chosen. Let us help you. These units provide a flow of temperature controlled fluid or Polyalphaolefin liquid. The table below shows a comparison of conventional hydraulic oils with the new PAO biobased lubricant from RLI. In addition, a PAO-based multi-purpose grease can be formulated to be both H1 and kosher approved. Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. Tiny bubbles these can cause major issues, such as shorter lubricant life, increased fluid compressibility, lower fluid viscosity and cavitation. Because of their controlled structure, PAOs do not contain lighter, more volatile (small) hydrocarbons. <<264FCCC095A7AD46A42A03D56AD5B96C>]>> Finally, greater oxidative stability extends oil life and keeps the compressor clean for a longer service interval. 93 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 161 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> package, an optimal PAO formulation will be different than that of mineral oils. Adding a PPD will reduce the pour point of a mineral oil, but it still will not achieve the performance of a PAO. In contrast, a mineral oil will require various antioxidants depending upon the structural makeup. %%EOF <> 101 0 obj The degree of the advantage may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. In these extreme services, a PAO-based lubricant is able to reach the area that requires lubrication and prevent damage or wear. While viscosity improvers can enhance VI, they can break down over time, resulting in diminished performance. DuPont, the DuPont Oval Logo, and all trademarks and service marks denoted with , or are owned by affiliates of DuPont de Nemours, Inc. unless otherwise noted. Our unique PAO 2.5cSt further improves flash/fire points by as much as 10 percent over other commercial polyalphaolefins. Rotary screw compressor oils formulated with PAO offer performance benefits not obtainable with a mineral-oil-based formulation. 0000001332 00000 n Although VI is an important indicator, when used alone, VI is misleading. In addition to the low temperature performance demonstrated by CCS, the volatility and viscosity index of the PAO 5 and 7 blend are improved over traditional PAO 6. This difference in polarity impacts many lubricant properties including elastomer compatibility, paint solvency, deposit control, and lubrication. 4 Chemicals PVC CPVC PP PVDF ABS. Some of the advantages of PAO-based lubricants are summarized in Table 5. 0000036809 00000 n They are also employed as base fluids in some wide temperature range greases. Our customers quickly realized the advantages in volatility, low-temperature viscometrics, VI and flash and fire points in equiviscous blends compared to 1-decene-based materials. The remaining synthetic lubricants are produced from other basestocks, including phosphate esters, polybutenes, silicones, perfluoroalkyl, and polyphenyl ethers. Furthermore, we are able to achieve these properties with non-decene alpha olefin feedstocks while providing advantages over existing products and extending feedstock supply. P.V.C. The PAOs . The Scanning Brookfield chart on this page demonstrates the difference in viscometrics between a Synfluid PAO and a pour point depressed mineral oil. <> Ethylene glycol dimethacrylate is the enoate ester that is the 1,2-bis (methacryloyl) derivative of ethylene glycol. endobj PAG basestocks are synthetic polymers manufactured using a polymerization process that combines monomers ethylene oxide (EO), propylene oxide (PO), and butylene oxide (BO) singly as homopolymers or in combinations to form a growing chain from a nucleophilic starter molecule, commonly an alcohol. 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. The information listed in parentheses is D-1418 nomencalture, common acronyms or common trade names. However, VI doesnt tell the whole story it only reflects the viscosity/temperature relationship between 40C and 100C. BioPreferred is a registered service mark of the United States Department of Agriculture. As the viscosity grade decreases, the volatility and high-temperature/high-shear viscosity will be limiting factors. 304 Stainless Steel Chemical Compatibility Chart ver 28-Oct-2022 Key to General Chemical Resistance - All data is based on ambient or room temperature conditions, about 64F (18C) to 73F (23C) A = Excellent C = Fair - Moderate Effect, not recommended 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. 0000161878 00000 n To improve seal compatibility of PAO-based lubricants, an ester is added to the formulation to add some polarity. The chart below shows the exceptional fire point advantages of using a 1-dodecene based PAO. Heres an overview of our production process: Copyright 2023 Chevron Phillips Chemical Company LLC. I love to talk about food, and I love to talk about Synfluid PAO! As the chart above shows, lower-viscosity oils can be made without sacrificing low volatility by using PAO base oils.

As temperature increases, a higher VI fluid will give increased fluid film thickness, which could result in lower wear. PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. 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). And we pioneered and patented our unique C12-based PAOs in the 1990s. However, PAOs can help. The chart below shows that the PAO has a higher specific heat, which means that the PAO is better at absorbing heat. End-users must first select a lubricant based upon its intended application, such as engine oil, transmission oil, hydraulic oil, wire rope lubricant, electric motor grease, etc. For instance, many producers have tailored production to Group II+ stocks at 118119 VI, just below the ambiguous Group III limit of 120VI. 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. trailer <<1656AD0EDA344239AE3641B5710538C3>]/Prev 1036271>> startxref 0 %%EOF 296 0 obj <>stream 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. Changes in low-temperature viscometrics and oxidative stability requirements demand higher-quality base oils. All rights reserved. 10.1 Introduction. . Adobe InDesign CS6 (Macintosh) Chemical Compatibility Guide General properties of low- and high-viscosity conventional PAO, and metallocene-catalyzed mPAO basestocks, are shown in Table 4. The lighter components cause poorer volatility properties as well as lower flash and fire points. When PAO 5 and PAO 7 are compared to equiviscous blends of other PAOs, the volatility advantage can be seen more clearly. With regard to performance, PAOs are able to maintain excellent thermal and oxidative stability at high operating temperatures in addition to the low-temperature benefits for which they are known. Consistent feedstocks give rise to consistent PAO quality, resulting in consistent finished fluid performance. Polyalphaolefin does not contain ring structures, double bonds, sulphur, nitrogen components or waxy hydrocarbons. 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. There are many advantages! Specifically, soybean-derived oils or other bio-derived oils alone would not meet some oxidative stability and low-temperature performance requirements. Level of maintenance and labor available. In addition, low viscosity SpectraSyn PAO products are hydrolytically stable, have good compatibility with mineral oils and are frequently combined with other synthetic basestocks (e .
