Compatibility testing is the best option. These oligomers are distilled and hydrogenated to yield specific molecular weight ranges that meet the viscosity grades that are desired. Grade Name. polyalphaolefin-based lubricants. Their polymerization can benefit greatly from the development of highly active and highly selective catalysts, as the catalysts strongly affect their properties. These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile. 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. PAO-based lubricants have good viscosity indices superior to lubricants based on Group I, II, and III basestocks of similar viscosity (without the addition of a viscosity improver). This is a far greater benefit than can be achieved from other base oils. The C12-derived PAOs were created to give better volatility, giving formulators four new options when choosing PAOs. Approximately 80% of synthetic lubricants used in the world are of three types. Polyglycols-40 to 125 C Technical White Oils are approved for incidental food contact at USDA-approved meat and poultry plants.

No matter what the combination of additive or base oil, one thing is certain: When you begin with a higher-quality base oil, you will achieve a better formulation in the end. The results indicate that the CSC 980 Tan grease has a running torque of 3.77 N-m versus 10.9 N-m for the same grease with an alternate base oil. Satisfactory to 120F (48C) Ratings: Chemical Effect A = Excellent. They may also be used to develop high-performance, environmentally friendly lubricants. 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. 0000022832 00000 n hb```b``nd`c``. If pour point is not a critical property in your application, then blending a PAO 5 and PAO 7 might give you that clear advantage that you are looking for. Polyalphaolefin Characteristics European specifications, as well as those in other regions, are expected to tighten. However, VI doesnt tell the whole story it only reflects the viscosity/temperature relationship between 40C and 100C. material chemical compatibility So yes, PAOs can provide flexibility in your food-grade base oil selection, depending upon your performance requirements. The rotary bomb bench test is a strong predictor of how base oils will perform in many automotive and industrial applications. 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. Due to this incompatibility with many but not all PAG lubricants, system change-outs from mineral oil to PAG-based lubricants may be costlier and take additional time. Lowering torque reduces the energy requirements of the equipment and improves grease distribution. 4 6 10.1 Introduction. In these extreme services, a PAO-based lubricant is able to reach the area that requires lubrication and prevent damage or wear. Benefits of the new system are a much higher viscosity index (VI), superior pour points and improved low-temperature fluidity, all of which contribute to improved energy efficiency. The Scanning Brookfield chart on this page demonstrates the difference in viscometrics between a Synfluid PAO and a pour point depressed mineral oil. A run through the test: This is the case for blending Synfluid PAO 5 and PAO 7. Polyalphaolefins offer great high temperature properties and low volatility. The advantages offered in oxidative stability, coupled with superior volatility and low-temperature viscometrics, clearly demonstrate that Synfluid PAOs are the highest-quality base oils available in the industry. 0000048689 00000 n When unsure of a components precise identity or version, the manufacturer 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). 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. Disadvantages of PAG-based lubricants are summarized in Table 3. The viscosity at an extreme pressure (hp) changes exponentially with pressure (P) as described in the following formula: a is the pressure coefficient for a base oil. 0000036915 00000 n PAG polymers, first discovered more than 150 years ago, saw their breakthrough application occur during World War ll. The primary difference between these two products is pour point. PAOs are the most common synthetic basestock used in industrial and automotive lubricants. In addition to meeting current limits, a lower viscosity will reduce energy consumption. Tiny bubbles these can cause major issues, such as shorter lubricant life, increased fluid compressibility, lower fluid viscosity and cavitation. endobj The Ethylene price in the Europe region was dull throughout the third quarter of 2022, which abetted the declining price trend of PAO throughout Q3 in Europe. 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. %PDF-1.4 % However, PAGs and PAOs are two totally different chemical types of synthetic base stocks. endstream 0000135019 00000 n For example, the fraction that has predominantly the 1-decene trimer (C30 oligomer) has a 100C viscosity of 4 cSt and is known as PAO 4. Furthermore, the process is a simpler, more energy-efficient route for grease production. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 159 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> PPDs act only on linear or waxy compounds, and these characteristics are absent from PAOs. 0000140193 00000 n 0000010623 00000 n It is really the formulators preference whether to increase the longevity of a vehicles moving parts, haul a heavier load, or save money at the fuel pump. Additionally, PAOs have high viscosity indices, which lead to less film thickness reduction at elevated temperatures. However, Synfluid PAOs can be formulated to be biodegradable and are well known for standing out from conventional base oils. 0000041967 00000 n While viscosity improvers can enhance VI, they can break down over time, resulting in diminished performance. When you compound this with difficult operating conditions, such as extreme temperatures, high loads or extended operations, a high-quality base oil may be necessary. 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. First, dont touch the gear box; you will burn your hand. More specialized polyolefins include polyisobutylene and polymethylpentene. 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. These 1-dodecene-based products (Synfluid 2.5, 5, 7 and 9cSt PAOs) are now recognized to have superior performance in their own applications. If a polyurea-based thickener is chosen in conjunction with a synthetic base oil, such as a polyalphaolefin (PAO), there is no compatibility risk to be expected. 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. 232 0 obj The chart compares two different formulations, one with PAO and another with Group III mineral oils The End of Test viscosity increase left very little room for error in the Group III formulation. %%EOF xmp.did:00801174072068118083E936383AAE83 This Chemical Compatibility Chart is a shorthand tool for describing the suitability of miniature fluidic and pneumatic component materials for use in contact with various chemicals.

Adding a PPD will reduce the pour point of a mineral oil, but it still will not achieve the performance of a PAO. PAO- and PAG-based lubricants are both hydrolytically stable and have low pour points. It is true there are many high-quality base oils around, but the highest quality is still achieved when Synfluid PAOs are chosen. As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. 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. Adobe InDesign CS6 (Macintosh) 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. The magnitude of these benefits will depend on the particular formulation. Synthetic basestocks, more so than in mineral oil basestocks, are the primary contributor to most of the basic properties of the lubricant, including oil or water solubility, low-temperature fluidity, lubrication, volatility, ignitability, and seal and paint compatibility.

However, moving to lower-viscosity oils is a possibility only if you can maintain a low Noack volatility for emissions control and lubricant stability. Use of PAG-based fluids and lubricants began to extend to other applications, first to quenchants and textile lubricants, then to many other lubricant categories, including anhydrous fire-resistant fluids, gear, compressor, and turbine fluids. application/pdf General properties of water-soluble, water-insoluble, and oil-soluble PAG basestocks are shown in Table 1. Effect of Base Oil Type on Gear Box Temperatures. 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. A grease formulated with Synfluid PAO and OMGs Calciplex grease precursor could yield a multipurpose product, which allows for consolidation of your grease inventory. The trend falls short when comparisons are made between PAOs and mineral oils, based solely on the VI. and PAO plays an integral part of meeting the challenge for top-tier oils. A drop-in replacement for petroleum, it's used in countless applications in many industries. Synfluid PAOs provide outstanding improvements in oxidation stability, volatility, water separability and viscometrics, greatly improving oil and hardware longevity. The combination of air and oil can often lead to foaming issues. Consistent feedstocks give rise to consistent PAO quality, resulting in consistent finished fluid performance. Sorry, you need to enable JavaScript to visit this website. One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. The lower volatility decreases oil replacement costs by reducing oil consumption. The chart below shows the gas chromatogram of PAO versus white mineral oil, illustrating the relative enhanced purity of PAO. This formulation achieved a 13% benefit when the PAO was directly substituted with Synfluid PAO. 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. Several synthetic base oil types fall into the SHC category. However, PAOs can help. 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. 0000027693 00000 n 11 46 The latest news, content and events about our company, initiatives, markets and products. Absolutely! Low-viscosity PAO fluids are used in automotive applications, such as engine oil and gear lubricants. Sometimes, one plus one can equal more than two.
