We look forward to helping you consolidate your grease cabinet! Aviation hydraulics require the use of PAOs because of the inherently high flash/fire points and low volatility. Other base oil properties need to be considered. The grease is then inspected for visual abnormalities and can be tested for penetration and four-ball wear change. However, PAOs can help. Level of maintenance and labor available. So yes, PAOs can provide flexibility in your food-grade base oil selection, depending upon your performance requirements. The vast number of high-quality base oil choices can be confusing when balancing fuel efficiency and wear protection. 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). Whichever low-viscosity base oil is used, it must exhibit viscosity stability and low volatility. 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. The table below shows a comparison of conventional hydraulic oils with the new PAO biobased lubricant from RLI. Sustained operations at elevated temperatures increase the rate of oxidation and other degradation reactions.

For other applications, PAOs safe and non-toxic nature allows it to be used where incidental food contact certification or kosher approval is necessary. The differences in flash, fire, volatility and viscosity highlight the flexibility benefits of using a Synfluid PAO. Synfluid PAOs are crafted from an on-purpose process that yields a consistent, high-quality product. Both lubricant types are used in industrial gearboxes, compressors, and even air conditioning systems. The remaining synthetic lubricants are produced from other basestocks, including phosphate esters, polybutenes, silicones, perfluoroalkyl, and polyphenyl ethers. To improve seal compatibility of PAO-based lubricants, an ester is added to . 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. PAOs help to balance the protection and energy conservation requirements in equipment because they are more Newtonian than mineral oils. The chart below shows the operating temperature range of a PAO-based, OMG process grease versus comparable mineral-oil-based grease. When unsure of a components precise identity or version, the manufacturer Finally, greater oxidative stability extends oil life and keeps the compressor clean for a longer service interval. After all, the reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. M/ B#z9lBGaB=]yz!sG !*, general guideline for pump material selection, from application/x-indesign to application/pdf. The ability of a lubricant to reach critical metal-to-metal interfaces in a gear system can be the difference between operation or shutdown. Absolutely! in extreme environments and to avoid plastic and elastomer compatibility problems. Two lubricants with the same VI may perform dramatically differently at low temperatures. Low-temperature fluidity and high-temperature thermal and oxidative stability are key factors for choosing a PAO. Adobe InDesign CS6 (Macintosh) 0000001764 00000 n
The C12-derived PAOs were created to give better volatility, giving formulators four new options when choosing PAOs. PAG-based lubricants provide many property and performance advantages over mineral oil-based and other synthetic lubricants, as outlined in Table 2. The term synthetic hydrocarbon (SHC) is a general term. Ethylene is produced by cracking either crude oil or natural gas. H|%

The uniquely beneficial quality of PAOs has been demonstrated in a series of European engine tests. 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. Synfluid PAOs have been carefully designed to yield oxidative induction times greater than 2,500 minutes with 0.5 percent antioxidant. All rights reserved. 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. Leaking fluids from equipment used in sensitive geographical areas can have long-term negative consequences on the environment. Some of the disadvantages of PAO-based lubricants are outlined in Table 6. High molecular weight compounds will degrade pour point, cold crank and other low-temperature viscometrics. Low molecular weight compounds will degrade other performance requirements, such as volatility, flash and fire points. %%EOF
Understanding the advantages and disadvantages of each can help end-users decide which option is best for a given application. You see, PAOs are carefully designed, not refined. So you can look to Synfluid PAO to help you formulate lubricants with both environmental benefits and outstanding performance properties. Why does this happen? First, dont touch the gear box; you will burn your hand. Jun 09 Comentarios desactivados en polyalphaolefin compatibility chart. PAOs are Newtonian fluids; in other words, their viscosities are fairly independent of shear rate. Although PAOs are not considered biobased themselves, in a blend they contribute certain performance benefits. Chemical Compatibility Guide The use of mineral oil-based lubricants in the world, however, is decreasing. 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. 2014-03-26T09:16:41-05:00 If you are using multiple greases, there are certain risks for misapplication, which are minimized with a multi-purpose grease. xmp.did:00801174072068118083E936383AAE83 mary berry grandchildren names . proof:pdf A grease formulated with Synfluid PAO and OMGs Calciplex grease precursor could yield a multipurpose product, which allows for consolidation of your grease inventory.

Group V oils also include esters and naphthenic oils. General properties of water-soluble, water-insoluble, and oil-soluble PAG basestocks are shown in Table 1. Lack of mineral oil solubility is a barrier to expanded use of PAG-based lubricants. PAOs are the most common synthetic basestock used in industrial and automotive lubricants. 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 . Specifically, soybean-derived oils or other bio-derived oils alone would not meet some oxidative stability and low-temperature performance requirements. Therefore, at high temperatures, it is advantageous to utilize a more stable base oil, specifically Synfluid PAO. 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. 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.
