Recent advancements in additive technology and synthetic base fluid manufacturing are pushing the performance edges that make current lubricant offerings better than ever. The trend falls short when comparisons are made between PAOs and mineral oils, based solely on the VI. Chemical Compatibility Guide 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. PAOs help to balance the protection and energy conservation requirements in equipment because they are more Newtonian than mineral oils. 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. from application/x-indesign to application/pdf European specifications, as well as those in other regions, are expected to tighten. Two lubricants with the same VI may perform dramatically differently at low temperatures. Additionally, PAOs have high viscosity indices, which lead to less film thickness reduction at elevated temperatures. Thats a hot topic! general guideline for pump material selection PAOs are Newtonian fluids; in other words, their viscosities are fairly independent of shear rate. PAO-based rotary screw compressor oil offers better performance in the compressor. 0000002995 00000 n
We expect that specifications for driveline fluids will continue to tighten due to pressure from energy conservation, improved transmission design and fluid longevity. For instance, excellent water separation improves compressor operability by reducing the chance of emulsion formation. Sorry, we couldn't find anything that matched your search, 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.

Compatibility testing is the best option. PPDs act only on linear or waxy compounds, and these characteristics are absent from PAOs. Volatility is a concern for many applications, especially where higher operating temperatures occur or longer service life is desired. The chart below shows a comparison of the foaming characteristics of our Synfluid mPAO high-viscosity base oils with traditional high-viscosity PAO 40 and 100 cSt base oils. As temperature decreases, a higher VI fluid will have reduced viscous drag, which could lead to higher horsepower and energy efficiency. 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. Using the same PAO, we achieved 15 percent higher oxidative stability by increasing the A.O. One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. polyalphaolefin compatibility chart - ks-sousahonorband.org 0000007470 00000 n
The ability of a lubricant to reach critical metal-to-metal interfaces in a gear system can be the difference between operation or shutdown. Weve got you covered!

However, moving to lower-viscosity oils is a possibility only if you can maintain a low Noack volatility for emissions control and lubricant stability. To help you optimize your application, Chevron Phillips Chemical offers a wide variety of PAOs delivering oxidative and thermal stability advantages. Ethylene glycol dimethacrylate is the enoate ester that is the 1,2-bis (methacryloyl) derivative of ethylene glycol. The rotary bomb bench test is a strong predictor of how base oils will perform in many automotive and industrial applications. in extreme environments and to avoid plastic and elastomer compatibility problems. Polyalkylene glycol (PAG) and polyalphaolefin (PAO) are two synthetic lubricant options for industrial applications. 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. This difference in polarity impacts many lubricant properties including elastomer compatibility, paint solvency, deposit control, and lubrication.

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. Sustained operations at elevated temperatures increase the rate of oxidation and other degradation reactions. 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. Youre not kidding! Synfluid PAOs also have a very high degree of saturation, which in lubricants provides oxidative stability. A formulator choosing the right base oil is like a craftsman choosing the right tool it needs to fit the job. . PAOs are considered a very pure substance since they are derived from petrochemically pure ethylene and then from 1-decene or 1-dodecene, which could be considered a further purification step. <>stream
Both basestock types have low volatility and high fire points (when stabilized) for a given viscosity grade. Grade Name. The grease is then inspected for visual abnormalities and can be tested for penetration and four-ball wear change. Since then, the company has expanded PAO as well as ethylene production, both basic building blocks for many petrochemical processes.

MOLYKOTE PAO Polyalphaolefin Oil - DuPont Because of their controlled structure, PAOs do not contain lighter, more volatile (small) hydrocarbons. PAOs offer exceptionally low volatility due to their controlled formation, which yields carefully designed molecular weights. Keys for Proper Grease Selection - Machinery Lubrication There are other advantages, such as oxidative and thermal stability, which you would naturally expect from a PAO-based product. This will increase the dependence on high-quality base oils such as PAOs. Compatibility testing is generally carried out at high temperatures, simulating an accelerated life and poor or stressful conditions for the plastic and elastomer/rubber. These requirements or specifications will generally identify or recommend a product type (mineral oils, synthetic fluids, or bio-based fluids) and the proper performance requirements (developed into the lubricant by the component chemistry) to allow the machinery to run at an optimum level. The effects of the shear rate differences are even more exaggerated at low-temperature startup conditions, when the lubricant function is critical for equipment protection. PAG-based lubricants have excellent viscosity indices significantly better than PAO-based lubricants of the same viscosity grade. 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. The superior benefits of PAOs enable formulators to meet these challenges. Defense Daily subscriber and registered users, please log in here to access the content. However, Synfluid PAOs can be formulated to be biodegradable and are well known for standing out from conventional base oils. A product developed by Renewable Lubricants Inc.
