endobj Adding a PPD will reduce the pour point of a mineral oil, but it still will not achieve the performance of a PAO. PAO-based lubricants offer a significant advantage in oxidative stability. You see, PAOs are carefully designed, not refined. There are multiple considerations when determining the best synthetic lubricant for a particular application, but knowledge of the general properties of the synthetic lubricant types being considered is the starting point. Process Chemical Compatibility Guide In both cases, the reduction in volatility will translate to lower oil consumption and reduced engine varnish over the life of the oil. The information listed in parentheses is D-1418 nomencalture, common acronyms or common trade names. Ethylene is produced by cracking either crude oil or natural gas. and PAO plays an integral part of meeting the challenge for top-tier oils. As oil volatilizes, the viscosity increase will result in poorer overall performance. 0000001605 00000 n
polyalphaolefin compatibility chart. The lower volatility decreases oil replacement costs by reducing oil consumption. PAOs on the other hand are derived from a clearly defined processing technology using petrochemically pure alpha olefins. Using the same PAO, we achieved 15 percent higher oxidative stability by increasing the A.O. 180 0 obj There are distinct advantages in volatility and low-temperature viscosity.

PAOs also resist viscosity increases upon oxidation, which is important in sequence IIIE and VW T4 engine tests. As the chart above clearly demonstrates, the difference in viscosity as a function of shear rate is magnified as temperature decreases. 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 lowers their volatility, creates less hydrocarbon tailpipe emissions and raises the flash point. Group III mineral oils and Group IV PAOs are not of the same quality. 0000000995 00000 n
One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. Ethylene glycol dimethacrylate is the enoate ester that is the 1,2-bis (methacryloyl) derivative of ethylene glycol. As temperature decreases, a higher VI fluid will have reduced viscous drag, which could lead to higher horsepower and energy efficiency. The tests used below were the Cold Cranking Simulator for high shear (about 10-1 sec-1) and Brookfield viscosity for low shear (about 2 sec-1) each measured at -20C. <> A run through the test: John Sherman is Shell Project Lead PAG Lubricant Technology, Industrial Oils and Tech Services; Robert Profilet is Technology Manager, Industrial Lubricants; Warren Cates is Shell Senior Researcher, Industrial Oils and Tech Services; Iris Song is Shell Engineer, Industrial Oils and Tech Services; and Sameer Sathaye is Shell Project Leader Industrial Oils, Industrial Oils and Tech Services.

Bk.2z3)))lBShBSX!D !DOaBBB*=]!z For instance, boosting the additive package with an additional 0.4% aminic antioxidant, in combination with the Synfluid PAO base oil, achieved a 35 percent improvement in HPDSC results. 0000000416 00000 n
Oxidative stability is a critical property enabling oils to resist sludge formation and degradation while in service. Polyalphaolefins (PAO)-60 to 125 C Stable, lubricious fluids compatible with most plastics and elastomers. Two major types of synthetic basestockspolyalkylene glycols (PAG) and polyalphaolefin (PAO)and the lubricants formulated from them, will be compared. Please dont hesitate to reach out to us if you have any questions! In contrast, the Synfluid PAO formulation achieves a pass with as little as 30 percent PAO, the balance being Group I mineral oil. 1 - High Resistance 2 - Limited Resistance 3 - No Resistance . News & Technology for the Global Energy Industry. The chart below shows the Noack volatility for both 1-decene and 1-dodecene based PAOs of varying viscosities. Youre not kidding! PAOs help to balance the protection and energy conservation requirements in equipment because they are more Newtonian than mineral oils. The chart below illustrates how Chevron Phillips Chemical has come up with an economical solution to a VW T-4 engine test. Having a high viscosity index helps to protect an engine at temperature extremes. The chart below shows the effect of two different shear rate viscosity determinations on three different fluids (4 cSt at 100C) and the dramatic differences between them. Its estimated that over 100 million gallons of fluids leak from hydraulic machinery and other lubricant equipment in North America each year! The chart below shows rotary bomb (ASTM D2272) results between Synfluid PAOs and some mineral oils. The differences in flash, fire, volatility and viscosity highlight the flexibility benefits of using a Synfluid PAO. PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. PAG-based lubricants are commonly used in compressors, gearboxes, air conditioning systems, metalworking, quenching, and hydraulic systems where fire-resistance or environmental acceptability are required. We have measured a 25 percent improvement in oxidation induction times simply by decreasing the test temperature by 10 degrees.

This is the case for blending Synfluid PAO 5 and PAO 7. 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. However, unlike foaming, entrained air can be a difficult problem to treat with additives. 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. General properties of low- and high-viscosity conventional PAO, and metallocene-catalyzed mPAO basestocks, are shown in Table 4. xref
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. Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene. 0000016208 00000 n
PPDs act only on linear or waxy compounds, and these characteristics are absent from PAOs. xmp.did:F87F1174072068118083E936383AAE83 Heavier components adversely affect low-temperature performance and pour point. Whether its transportation or industrial lubes, greater fuel efficiency means lower operating costs. Low-viscosity PAO fluids are used in automotive applications, such as engine oil and gear lubricants. Disadvantages of PAG-based lubricants are summarized in Table 3. This is just one of the many performance advantages of Synfluid mPAO. Since there are no other discernable compounds, Synfluid PAOs are more readily biodegradable and can be used for some food applications. polyalphaolefin compatibility chart. 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. Group V oils also include esters and naphthenic oils. Chemical Compatibility Guide - Galvanized Steel For UltraTech Spill Containment Products This listing was prepared to provide guidance to the chemical compatibility of UltraTech Spill Containment Products which are manufactured and constructed of galvanized steel. Several synthetic base oil types fall into the SHC category. 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. Polyglycols-40 to 125 C For white oil applications, this high saturation level would give a greater degree of chemical inertness. More importantly, however, was product performance. The VI trend is only true for a family of base oils. It is true there are many high-quality base oils around, but the highest quality is still achieved when Synfluid PAOs are chosen. 184 0 obj Remember, PAOs are carefully designed, not refined. 2023 Access Intelligence, LLC - All Rights Reserved. xmp.did:F87F1174072068118083E936383AAE83 Specific tests such as the Volkswagen T-4, TDI and Peugeot TU-5 have increased the demand for higher-quality base oils.

Therefore, reducing the temperature is generally beneficial in extending the life of a lubricant. Typically, petroleum-base oils are not synonymous with terms like green or environmentally friendly. With Synfluid PAO 4 cSt having a 73C ppt and 40C viscosity of 2,380 cSt, a PPD is not necessary. 2014-03-26T09:16:41-05:00 Since they are fully synthetic, Synfluid PAOs are extremely pure and provide inherent benefits in oxidative stability and viscosity performance at temperature extremes. Low molecular weight compounds will degrade other performance requirements, such as volatility, flash and fire points. For the highest quality and performance, choose Synfluid PAO. Finally, greater oxidative stability extends oil life and keeps the compressor clean for a longer service interval. Later used in many industrial applications from compressor, hydraulic, and turbine fluids to gear oils and metalworking fluids. Adobe InDesign CS6 (Macintosh) 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. Because a certain level of biodegradability can be achieved without sacrificing PAOs key benefits, a finished lubricant based on a PAO/biobased blend will maintain superior properties over an extended period of time, resulting in less waste. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 162 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> Understanding the advantages and disadvantages of each can help end-users decide which option is best for a given application. The chart below shows the gas chromatogram of PAO versus white mineral oil, illustrating the relative enhanced purity of PAO.

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. The viscosity of the base oil is largely irrelevant in relation to the compatibility risks with the thickener. 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. It is a synthetic hydrocarbon (SHC) that mimics the best hydrocarbon (branched, non-ring) structure found in mineral oils and so corrects for many disadvantages of using mineral oil lubricants, including poor low-temperature fluidity, poor viscosity index, sludge deposits, and high volatility. The lighter components cause poorer volatility properties as well as lower flash and fire points. This provides several advantages, one of which can be illustrated by gas chromatography. There are other advantages, such as oxidative and thermal stability, which you would naturally expect from a PAO-based product.
