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. Because of this extensive chemical compatibility, which spans considerable concentration and temperature ranges, . Because PAOs have a diverse, highly branched isoparaffin structure, they provide excellent low-temperature viscometrics and very low pour points (ppt) without adding PPDs. Polypropylene Satisfactory to 120 F. 4. You see, PAOs are carefully designed, not refined. The higher the coefficient, the greater the change in viscosity at elevated pressures. 0000001764 00000 n converted It is not reactive at room temperatures, except by strong oxidizing agents, and some solvents cause swelling. Therefore, they are commonly blended or combined with organic ester synthetic base oils to provide a blended base oil that does not have these negative characteristics. But what happens below 40C? <> This is one clear benefit of using a carefully designed base oil. (2;2222;;;;;;;;;;;;;;;;;@@@@@;@@@@@@@@@@@@@@@@@@@@@ " B As a result, the jump in the viscosity adversely effects the ability to pump at low temperatures. Both lubricant types are used in industrial gearboxes, compressors, and even air conditioning systems.

In addition, a PAO-based multi-purpose grease can be formulated to be both H1 and kosher approved. endobj The dodecene-based products offer lower volatility at comparable viscosities to the decene-based products. Some of the advantages of PAO-based lubricants are summarized in Table 5. xmp.did:00801174072068118083E936383AAE83 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. This chart illustrates another benefit of using Synfluid PAOs at increased antioxidant treat rates. The table below shows how our new Synfluid mPAOs offer significant advantages in pour point and viscosity index over conventional high-viscosity PAOs. In addition to meeting current limits, a lower viscosity will reduce energy consumption. And we pioneered and patented our unique C12-based PAOs in the 1990s. 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. The more similar in polarity the lubricants are, the more similar they will behave in the properties mentioned. 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. Group III mineral oils and Group IV PAOs are not of the same quality. Synfluid PAOs are designed to provide stable viscosities at low temperature and excellent viscometrics and deliver oxidative stability. Sorry, you need to enable JavaScript to visit this website. While pour point is one consideration, a formulator has to take into account the total specification needs. Chemical Compatibility Chart (cont.) Polyalphaolefins offer great high temperature properties and low volatility. guide for chemical uses For example, one would not be able to make an 0W-20 oil with a C12-derived PAO as the viscosities are too high. There are distinct advantages in volatility and low-temperature viscosity. Whichever low-viscosity base oil is used, it must exhibit viscosity stability and low volatility. General properties of water-soluble, water-insoluble, and oil-soluble PAG basestocks are shown in Table 1. 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). While typical hydraulic oils are not biodegradable, this new system achieves the ultimate biodegradation rating (ASTM D5864 PW1) and even improves several performance parameters, not previously attainable. These include the tendency to shrink seals and trouble dissolving common oil additives. Sometimes, one plus one can equal more than two. Compatibility testing includes heating and holding grease for a specified time at assumed operating temperature for mixtures of 10:90, 50:50 and 90:10. This formulation achieved a 13% benefit when the PAO was directly substituted with Synfluid PAO. These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile. As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. PAG-based lubricants have excellent viscosity indices significantly better than PAO-based lubricants of the same viscosity grade. Give us a call.

Group IIIB was unable to consistently pass the TDI or M111 tests. Several synthetic base oil types fall into the SHC category. Typically, as the viscosity drops, the volatility increases. 0000002388 00000 n As the chart above clearly demonstrates, the difference in viscosity as a function of shear rate is magnified as temperature decreases. These oligomers are distilled and hydrogenated to yield specific molecular weight ranges that meet the viscosity grades that are desired. 0000035336 00000 n To mitigate this effect, We recommend taking a look at Synfluid PAO 5 and PAO 7, due to their excellent Noack volatilities of 5.5% and 2.3%, respectively. 0000031839 00000 n 0000000549 00000 n However, Synfluid PAOs can be formulated to be biodegradable and are well known for standing out from conventional base oils. For instance, a 100 percent aminic antioxidant package will yield the best performance in the Rbot test for PAO. 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. Some specifications have a low-temperature MRV requirement. 10.1 Introduction. Why does this happen? Since PAO fluids are synthetic hydrocarbons, they are compatible with and often combined with mineral-based oils. in extreme environments and to avoid plastic and elastomer compatibility problems. Compatibility testing is generally carried out at high temperatures, simulating an accelerated life and poor or stressful conditions for the plastic and elastomer/rubber. However, unlike foaming, entrained air can be a difficult problem to treat with additives. endobj This property coupled with excellent oxidative stability provides a formidable component in an engine oil formulators toolbox.

This will increase the dependence on high-quality base oils such as PAOs. startxref Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. 0000012483 00000 n This is a recurring situation and is what led to the development of 1-dodecene based Synfluid PAOs in 1995. False 0000000776 00000 n These compounds are not discernable in Synfluid PAOs. 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. Recent advancements in additive technology and synthetic base fluid manufacturing are pushing the performance edges that make current lubricant offerings better than ever. 11 46 Although PAOs are not considered biobased themselves, in a blend they contribute certain performance benefits. All rights reserved. The absence of these structures and materials results in a very non-polar base oil with a high viscosity index (of approximately 130), excellent low-temperature flow and pour-point characteristics, good oxidation stability and compatibility with mineral oils, paints and seals commonly found in lube oil systems. Three stringent test standards required by Volkswagen and Mercedes-Benz engines show the impact of the variability of Group III oils: This data illustrates lot-to-lot variability, which has been recognized for the Group III oils. Grease is a solid to semi-fluid lubricant, typically used for difficult to service equipment, such as bearings or suspension systems. In order of volume used, they are: polyalphaolefins (PAOs), organic esters, and polyglycols. 9 0 obj <>stream Synfluid PAOs, in addition to NSF H1 qualification, are also available as kosher approved products. To improve seal compatibility of PAO-based lubricants, an ester is added to the formulation to add some polarity. But wait, it gets even better! Air is usually a really poor lubricant, so your frustration is understandable! Specific heat is the amount of heat per unit mass required to raise the temperature one degree Celsius. Use our Chemical Compatibility Chart as guide for evaluating the resistance of polymer and metal materials to a wide range of chemicals found in industrial . More uniform in structure than conventional PAO basestocks, they provide similar advantages of high viscosity indices, excellent low-temperature fluidity, and shear stability but with additional thickening ability. Leaking fluids from equipment used in sensitive geographical areas can have long-term negative consequences on the environment. For other applications, PAOs safe and non-toxic nature allows them to be used where incidental food contact certification or kosher approval is necessary. Better heat transfer coefficients, increased lubricity and the basic chemical structure of PAOs all contribute to the lower temperature in the gearbox. When possible, testing compatibility between the specific PAG lubricant to be used and the specific seal types or paints to be used is recommended. As shown in the chart below, our PAOs have shown very little fluctuation over the years, with stable viscosities at 100, 40 and -40C even as weve made improvements to characteristics such as oxidative stability. trailer <<1656AD0EDA344239AE3641B5710538C3>]/Prev 1036271>> startxref 0 %%EOF 296 0 obj <>stream PAO-based greases are typically used at temperatures over 100C because of thermal and oxidative concerns.

The key to unlocking the full potential of your formulation requires using the right combination and concentration of antioxidant and Synfluid PAO. The vast number of high-quality base oil choices can be confusing when balancing fuel efficiency and wear protection. Lowering torque reduces the energy requirements of the equipment and improves grease distribution. 0 Synfluid PAOs are qualified as technical white oils (per 21 CFR 178.3620(b)(1)) due to their clear, bright color and exceptional UV properties. You would expect the viscosity to improve with a lower pour point, but the opposite is true. As the chart below shows, greater energy efficient, lower viscosity oils can be made through the selection of PAO, without sacrificing volatility. The differences in flash, fire, volatility and viscosity highlight the flexibility benefits of using a Synfluid PAO. This is a far greater benefit than can be achieved from other base oils. Since we are all concerned with the protection of our environment, it is important to note some PAOs can be formulated with other components into biodegradable fluids. Naval Research Laboratory (USNRL) was begun to develop hydraulic fluids that would be more fire-resistant than the ones used at the time based on mineral oil. 2014-03-26T09:16:41-05:00 As oil volatilizes, the viscosity increase will result in poorer overall performance. 95 0 obj Polyglycols-40 to 125 C Cant find what youre looking for? Synthetic lubricants can be very different chemically and what defines those differences are the basestocks used as the basis for the lubricant. and PAO plays an integral part of meeting the challenge for top-tier oils.
