Effect of Base Oil Type on Gear Box Temperatures. endobj 0000003107 00000 n They have different characteristics, meaning that one may be superior to the other under certain circumstances. Heavier components adversely affect low-temperature performance and pour point. The 2002 U.S. Farm Bill Act mandates government agencies to purchase environmentally safe, biobased (vegetable oil) lubricants. Let us help you. Furthermore, the arbitrary distinction of 120 VI between Group II and III oils makes the quality requirements even more confusing. 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. The chart below shows the trends in industry specifications regarding low-temperature performance relative to Synfluid PAO. The limits on lowering the viscosity grade are tied to the base oil properties. 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. Understanding the advantages and disadvantages of each can help end-users decide which option is best for a given application. There are other advantages, such as oxidative and thermal stability, which you would naturally expect from a PAO-based product. Synfluid PAOs also have a very high degree of saturation, which in lubricants provides oxidative stability. polyalphaolefin compatibility chart. Process Chemical Compatibility Guide 0000103071 00000 n 0000134768 00000 n PAO basestocks using conventional catalysts are commercially produced in five low-viscosity grades and two high-viscosity grades to a maximum viscosity of 100 centistokes (cSt) at 100C. For instance, Chemtool Incorporated utilizes Synfluid PAOs in greases, and they have been able to formulate their products to take specific advantage of Synfluid PAO properties, yielding improvements in low-temperature mobility and torque. 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. PAOs are Newtonian fluids; in other words, their viscosities are fairly independent of shear rate. These excellent pour points are achieved while increasing the viscosity indices (VI) over traditional HV PAO. Some of the disadvantages of PAO-based lubricants are outlined in Table 6. 3.0 CHEMICAL COMPATIBILITY GUIDE FOR METALLIC MATERIALS In addition to this chemical compatibility chart, report TR-60C, Bal Seal has two other reports: report TR-60A "Chemical Compatibility Guide for Bal Seal PTFE, Filled PTFE, and Polyethylene Seal Copyright 2023 Chevron Phillips Chemical Company LLC. According to analysis conducted by Kline & Co., more than 78% of all lubricant requirements in the world annually are met with the use of mineral oil-based fluids. This same technology can also be beneficial for biobased gear lubricants, chain and cable lubricants/greases, and other applications for equipment used in sensitive environmental areas. These advantages are achieved without the need for VI improvers or other additives, which may promote other deleterious effects as they degrade. A drop-in replacement for petroleum, it's used in countless applications in many industries. Since then, the company has expanded PAO as well as ethylene production, both basic building blocks for many petrochemical processes. xmp.id:B2FC01B10F2068118083E936383AAE83 When you compound this with difficult operating conditions, such as extreme temperatures, high loads or extended operations, a high-quality base oil may be necessary. Oxidative stability is a critical property enabling oils to resist sludge formation and degradation while in service. Adding a PPD will reduce the pour point of a mineral oil, but it still will not achieve the performance of a PAO. With many new base oils being introduced to the market, lubricant consistency can really be a challenge. endobj Polyolefins, including poly (ethylene), poly (-olefin), poly (styrene), and poly (dienes), are the most widely-used polymer materials. Give us a call, and well be happy to discuss our high-quality Synfluid PAOs with you. 142 0 obj <>stream %PDF-1.6 % Compatibility testing is the best option. 91 0 obj 0000001493 00000 n The plot below shows a comparison of the air release times exhibited by ISO VG 320 blends composed of our Synfluid mPAOs, and traditional HV PAOs with PAO 8 cSt. PAOs also resist viscosity increases upon oxidation, which is important in sequence IIIE and VW T4 engine tests. 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. Since we use essentially pure 1-decene or 1-dodecene to produce Synfluid PAOs, there is a narrow isomeric distribution for each oligomer. Reasons to change from mineral oil-based lubricants to synthetics despite the increase in cost include: Advances in equipment technology have resulted in more demanding lubricant conditions and requirements, many beyond the capabilities of mineral oil-based lubricants. <]/Prev 170099>> 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. Getting the air to release from the lubricant is vital to allowing the lubricant to do its job. As pressure increases, so too does the viscosity of the lubricant.

A relatively simple test, the criteria of the test varies depending on which grease manufacturer you are dealing with. 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. As temperature increases, a higher VI fluid will give increased fluid film thickness, which could result in lower wear. Synthetic lubricants can be very different chemically and what defines those differences are the basestocks used as the basis for the lubricant. 0000042568 00000 n 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. So yes, PAOs can provide flexibility in your food-grade base oil selection, depending upon your performance requirements. Although VI is an important indicator, when used alone, VI is misleading. We look forward to helping you consolidate your grease cabinet! 0000012542 00000 n The viscosity at an extreme pressure (hp) changes exponentially with pressure (P) as described in the following formula: a is the pressure coefficient for a base oil. Fluids are typically subjected to various shear and temperature conditions. 179 0 obj 0 These are areas where PAOs excel. The table below shows how our new Synfluid mPAOs offer significant advantages in pour point and viscosity index over conventional high-viscosity PAOs. There can be many benefits from choosing a high VI base fluid. mary berry grandchildren names . As the viscosity grade decreases, the volatility and high-temperature/high-shear viscosity will be limiting factors. Youre not kidding! 0000033361 00000 n They're found in everyday food and available as supplements. And we pioneered and patented our unique C12-based PAOs in the 1990s. The PAOsare produced through synthesizing oligomers of either 1-decene or 1-dodecene. In order of volume used, they are: polyalphaolefins (PAOs), organic esters, and polyglycols. PAO-based lubricants offer a significant advantage in oxidative stability. endobj The combination of air and oil can often lead to foaming issues.

False Actions. polyalphaolefin compatibility chart Posted by . 2014-03-26T09:12:57.905-05:00 PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. Initially, it was intended to fill the gap in supply and was found to be exceptionally suitable for applications where extremely low pour points were not necessary. The chart below shows the operating temperature range of a PAO-based, OMG process grease versus comparable mineral-oil-based grease. You can see a medical doctor for your burn, but Dr. Ken Hope can help with your base oil and formulation challenges. Eight standard model Portable Liquid Chillers and ten standard model PAO Carts. The direct feedstock (normal alpha olefin NAO) is produced through the chain growth and displacement process for producing petrochemically pure alpha olefins. The current trend toward lower viscosities, while providing for extended drain capabilities, does present an interesting challenge for base oils. Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants. D = Severe Effect, not recommended for ANY use. 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. Group IIIB was unable to consistently pass the TDI or M111 tests. The lower volatility decreases oil replacement costs by reducing oil consumption.
