polyalphaolefin compatibility chart

Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. 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. 0 One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. Use of PAG-based fluids and lubricants began to extend to other applications, first to quenchants and textile lubricants, then to many other lubricant categories, including anhydrous fire-resistant fluids, gear, compressor, and turbine fluids. At that time, both fires on U.S. Navy ships and aircraft were occurring due to the use of mineral oil-based hydraulic fluids. The degree of the disadvantage for seal and paint compatibility may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). In order of volume used, they are: polyalphaolefins (PAOs), organic esters, and polyglycols. The chart below illustrates how Chevron Phillips Chemical has come up with an economical solution to a VW T-4 engine test. They are usually derived from a small set of simple olefins ( alkenes ). This resistance to fire and flame propagation improves the margin of safety in the event of a hydraulic leak. Buna-N Satisfactory for "O . startxref 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. The PAOsare produced through synthesizing oligomers of either 1-decene or 1-dodecene. In the past three years, European specifications for volatility and oxidative stability have become significantly more stringent. Whether its transportation or industrial lubes, greater fuel efficiency means lower operating costs. CHEMICAL RESISTANCE CHART. The Scanning Brookfield chart on this page demonstrates the difference in viscometrics between a Synfluid PAO and a pour point depressed mineral oil. 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. With regard to performance, PAOs are able to maintain excellent thermal and oxidative stability as well as the low-temperature benefits they are known for. @0NI$$I)I$JRI$I$$I)I$JRI$'I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$L$I$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$IJI$RI$I%)ekvEJX'I$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJL'I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI2tI%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RI$I%)$IJI$RID4>))I$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I$JRI$I$$I)I*4V~u. 232 0 obj In contrast, the Synfluid PAO formulation achieves a pass with as little as 30 percent PAO, the balance being Group I mineral oil. In both cases, the reduction in volatility will translate to lower oil consumption and reduced engine varnish over the life of the oil. It is possible to get added property benefits from C12-based Synfluid PAOs. Chemical kinetics tell us that if you reduce the temperature, you will reduce the reaction rate. This lowers their volatility, creates less hydrocarbon tailpipe emissions and raises the flash point. Because of their controlled structure, PAOs do not contain lighter, more volatile (small) hydrocarbons. The rotary bomb bench test is a strong predictor of how base oils will perform in many automotive and industrial applications. A grease formulated with Synfluid PAO and OMGs Calciplex grease precursor could yield a multipurpose product, which allows for consolidation of your grease inventory. Absolutely! These include the tendency to shrink seals and trouble dissolving common oil additives. Their polymerization can benefit greatly from the development of highly active and highly selective catalysts, as the catalysts strongly affect their properties. PAG polymers, first discovered more than 150 years ago, saw their breakthrough application occur during World War ll. 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).

Focusing on the components of the additive package can further influence the performance of the formulation. %%EOF PAOs are the most common synthetic basestock used in industrial and automotive lubricants. Sustained operations at elevated temperatures increase the rate of oxidation and other degradation reactions. One way to achieve a higher VI base fluid is to shift from a decene-based PAO to a dodecene-based PAO. You can see a medical doctor for your burn, but Dr. Ken Hope can help with your base oil and formulation challenges. The use of synthetic or man-made lubricants in various industrial and automotive applications are becoming commonplace and continues to expand into applications where only mineral oil-based fluids had been used. They are also employed as base fluids in some wide temperature range greases. The benefit of a lubricant to the end user is an important question, and the behavior of a base oil is only one of many variables affecting the performance of a finished formulation. Since there are no other discernable compounds, Synfluid PAOs are more readily biodegradable and can be used for some food applications.

Some specifications have a low-temperature MRV requirement. In addition to these properties, weve also seen a significant reduction in the traction coefficient as compared to conventional high-viscosity PAOs. MOLYKOTE. 0000036809 00000 n Synfluid mPAOs exhibit faster air release times, particularly when comparing the 100 cSt blends. There are multiple formulations behind the science of synthetic lubricants that can complicate making the right choice for any application. This is a far greater benefit than can be achieved from other base oils. 2014-03-26T09:12:59.004-05:00 0000042568 00000 n Low molecular weight compounds will degrade other performance requirements, such as volatility, flash and fire points. This chart illustrates another benefit of using Synfluid PAOs at increased antioxidant treat rates. Therefore, reducing the temperature is generally beneficial in extending the life of a lubricant. 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. Polyalphaolefin does not contain ring structures, double bonds, sulphur, nitrogen components or waxy hydrocarbons. 9 0 obj <>stream application/pdf 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. This article will discuss the most common synthetic fluids aiming to help end-users make the right choice for their applications. To get a superior lubricant, you need to start with a superior base oil. 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. 0000001605 00000 n Weve got you covered! Specifically, soybean-derived oils or other bio-derived oils alone would not meet some oxidative stability and low-temperature performance requirements. Reducing the viscosity of engine and drivetrain oils lowers fuel consumption by decreased churning losses and viscous drag. The primary difference between these two products is pour point. The trend falls short when comparisons are made between PAOs and mineral oils, based solely on the VI. So, whether used for gear or engine oils, PAOs provide more consistent properties and a level of purity not available from other base oil groups. 0000004968 00000 n PAOs help to balance the protection and energy conservation requirements in equipment because they are more Newtonian than mineral oils. In addition, a PAO-based multi-purpose grease can be formulated to be both H1 and kosher approved. 0000018828 00000 n PAO-based lubricants have good viscosity indices superior to lubricants based on Group I, II, and III basestocks of similar viscosity (without the addition of a viscosity improver). Note the differences between a VHVI mineral oil and Synfluid Polyalphaolefin (PAO) 5 in the Scanning Brookfield chart below. Defense Daily subscriber and registered users, please log in here to access the content. 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. 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. Naval Research Laboratory (USNRL) was begun to develop hydraulic fluids that would be more fire-resistant than the ones used at the time based on mineral oil. Lowering torque reduces the energy requirements of the equipment and improves grease distribution. material chemical compatibility For example, one would not be able to make an 0W-20 oil with a C12-derived PAO as the viscosities are too high. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 164 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> RESISTANCE CHART RATINGS CHEMICAL EFFECT A No effectExcellent B Minor effectGood 2. 0000031839 00000 n Water for liquid cooling comes from different sources.
