Were a company with deep-rooted values, and were looking for people like you to join our team. Aviation hydraulics require the use of PAOs because of the inherently high flash/fire points and low volatility. And we pioneered and patented our unique C12-based PAOs in the 1990s. PAOs on the other hand are derived from a clearly defined processing technology using petrochemically pure alpha olefins. 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. Oils made with PAOs demonstrate an inherently high viscosity index and maintain excellent low-temperature performance, compared with mineral oils. In addition to meeting current limits, a lower viscosity will reduce energy consumption. With todays oils requiring a higher-quality lubricant basestock to meet more stringent tests, polyalphaolefins are perfectly tailored and consistently manufactured to meet the challenge. general guideline for pump material selection 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). Specific heat is the amount of heat per unit mass required to raise the temperature one degree Celsius. The primary difference between these two products is pour point. Furthermore, the arbitrary distinction of 120 VI between Group II and III oils makes the quality requirements even more confusing. Synfluid PAOs have helped you to meet industry specifications in the past. 1 - High Resistance 2 - Limited Resistance 3 - No Resistance . PAO-based greases are typically used at temperatures over 100C because of thermal and oxidative concerns. With many new base oils being introduced to the market, lubricant consistency can really be a challenge. 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. www.topworx.com Epoxy Polycarbonate PBT Brass 316 S.S. 304 S.S. 400 S.S.

Other base oil properties need to be considered. As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. High molecular weight compounds will degrade pour point, cold crank and other low-temperature viscometrics. From then on, the company introduced 1-dodecene-based PAOs in 1995, which have grown steadily in popularity. These properties translate into easier distribution of the grease and improved energy efficiency in the equipment. The VI trend is only true for a family of base oils. The superior low-temperature flow characteristics of PAOs ensure faster coating of critical parts in the compressor during startup, minimizing wear. This difference in polarity impacts many lubricant properties including elastomer compatibility, paint solvency, deposit control, and lubrication. %PDF-1.5

PAO- and PAG-based lubricants are both hydrolytically stable and have low pour points. 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. PAG lubricant basestocks can be designed to be water-soluble, water-insoluble (partial mineral oil compatibility), or oil-soluble, depending on the selection of starter molecules and monomers to be used in producing the polymer. 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. 4 Chemicals PVC CPVC PP PVDF ABS. The mineral oil has both lighter and heavier molecular weight materials. This lowers their volatility, creates less hydrocarbon tailpipe emissions and raises the flash point. The chart below shows how Synfluid PAOs can help meet these challenges with the excellent volatility properties of our PAO 5, 7 and 9 cSt grades. Ethylene glycol dimethacrylate is the enoate ester that is the 1,2-bis (methacryloyl) derivative of ethylene glycol. PAOs also resist viscosity increases upon oxidation, which is important in sequence IIIE and VW T4 engine tests. Understanding this advantage is important for optimizing the performance of todays fluids and improving the life of equipment. PAG- and PAO-based lubricants rarely compete in industrial applications. 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. Chemical Compatibility Guide However, PAOs can help. Please dont hesitate to reach out to us if you have any questions! We believe that it is possible to achieve a passing mark with even lower amounts of PAO, further reducing costs. 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. 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. In the chart below, we highlight how moving from a decene-based Synfluid PAO 6 to an iso-viscous dodecene-based fluid (resulting from a blend of PAO 5 and PAO 7) leads to a dramatic increase in VI. 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 lighter components cause poorer volatility properties as well as lower flash and fire points. Nine standard circulating fluids including d-Limonene, FC77 Flourinert, Galden, Lexol 408, Paratherm CR, Coolanol and PAO. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 159 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> June 16, 2022; Posted by usa volleyball national qualifiers 2022; 16 . 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. <<264FCCC095A7AD46A42A03D56AD5B96C>]>>
These are areas where PAOs excel. Recent advancements in additive technology and synthetic base fluid manufacturing are pushing the performance edges that make current lubricant offerings better than ever. In contrast, the Synfluid PAO formulation achieves a pass with as little as 30 percent PAO, the balance being Group I mineral oil. 0000001211 00000 n
endobj Synfluid PAOs have very narrow molecular weight ranges, which are attributed to our high-purity feedstocks. Ethylene is produced by cracking either crude oil or natural gas. 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. Challenges like these truly reveal the performance advantages of Synfluid PAOs. It is a synthetic hydrocarbon (SHC) that mimics the best hydrocarbon (branched) structure found in mineral oils.
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. This chart illustrates another benefit of using Synfluid PAOs at increased antioxidant treat rates.

Furthermore, these new formulations allow a range of ISO viscosity grades. Heres an overview of our production process: Copyright 2023 Chevron Phillips Chemical Company LLC. One way to achieve a higher VI base fluid is to shift from a decene-based PAO to a dodecene-based PAO. PAG-based lubricants are polar (water-soluble PAG > water-insoluble PAG > oil-soluble PAG), where PAO-based lubricants are essentially non-polar. 1. The chart below shows the exceptional fire point advantages of using a 1-dodecene based PAO. Synfluid mPAOs exhibit faster air release times, particularly when comparing the 100 cSt blends. Group V oils also include esters and naphthenic oils.

These combined benefits provide the properties required for severe service applications and extended drain intervals. 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. . Understanding the advantages and disadvantages of each can help end-users decide which option is best for a given application. These include the tendency to shrink seals and trouble dissolving common oil additives. The key to unlocking the full potential of your formulation requires using the right combination and concentration of antioxidant and Synfluid PAO. For the highest quality and performance, choose Synfluid PAO. The chart below shows the operating temperature range of a PAO-based, OMG process grease versus comparable mineral-oil-based grease. Two lubricants with the same VI may perform dramatically differently at low temperatures. BioPreferred is a registered service mark of the United States Department of Agriculture. 0000139372 00000 n
Thats a hot topic! Chemical Compatibility Chart (cont.) concentration from 0.5 percent to 1 percent. 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. Thermal conductivity is the measure of the ability to conduct heat. The properties mentioned above are in addition to the normally excellent performance you have come to recognize with PAO. Meet additional regulations (fire-resistance, environmental acceptability). However, PAGs and PAOs are two totally different chemical types of synthetic base stocks. endstream We have measured a 25 percent improvement in oxidation induction times simply by decreasing the test temperature by 10 degrees. 0000034812 00000 n
This resistance to fire and flame propagation improves the margin of safety in the event of a hydraulic leak. As temperature decreases, a higher VI fluid will have reduced viscous drag, which could lead to higher horsepower and energy efficiency. 0000018828 00000 n

For instance, many producers have tailored production to Group II+ stocks at 118119 VI, just below the ambiguous Group III limit of 120VI. Synfluid PAOs have been carefully designed to yield oxidative induction times greater than 2,500 minutes with 0.5 percent antioxidant. 0000135615 00000 n
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. 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. In addition, a PAO-based multi-purpose grease can be formulated to be both H1 and kosher approved. 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. The relationship between antioxidants (A.O.) Synthetic lubricants can meet these demands because they perform better than mineral oil-based lubricants in many or all the critical performance areas: reduced wear and friction, resistance to sludge formation, lower volatility, greater corrosion protection, and improved thermal and oxidative stability. One application in which they have not worked well is in high-temperature (high-pressure) reciprocating air compressors where valve deposits have been an issue. A process enhancement at Chevron Phillips Chemicals manufacturing facility has resulted in up to a 30 percent improvement in oxidative stability when used with aminic antioxidants in Rotary Bomb Oxidation Tests (RBOT). Actions. Aluminum is compatible with fluids such as polyalphaolefin (PAO), oil, ethylene glycol and water solutions (EGW), as well as Fluorinert, an electrically insulating inert perfluorocarbon fluid manufactured by 3M and used in many electronics cooling applications. The term synthetic hydrocarbon (SHC) is a general term. Applications for PAO-based lubricants expanded to circulating and gear oils. PAG basestocks are classified as a Group V oil, meaning a synthetic basestock that is not defined as a Group I, II, III, or IV base oil. Although PAOs are not considered biobased themselves, in a blend they contribute certain performance benefits. Our sustainability strategy encompasses the concerns and issues identified by our stakeholders and we are committed to addressing these issues. 2 shows the flow chart for producing Cu nanolubricants. Synthetic lubricants can be very different chemically and what defines those differences are the basestocks used as the basis for the lubricant.
