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. These are areas where PAOs excel. The trend falls short when comparisons are made between PAOs and mineral oils, based solely on the VI. 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. This difference in polarity impacts many lubricant properties including elastomer compatibility, paint solvency, deposit control, and lubrication. 176 0 obj 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. 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. Chemical Compatibility Guide To improve fuel economy, OEMs are moving toward lower-viscosity oils, even in heavy-duty diesel engines. 0000001211 00000 n This formulation achieved a 13% benefit when the PAO was directly substituted with Synfluid PAO. PAOs are Newtonian fluids; in other words, their viscosities are fairly independent of shear rate. endobj Polyalphaolefin does not contain ring structures, double bonds, sulphur, nitrogen components or waxy hydrocarbons. 0000016208 00000 n Finally, due to their excellent response to antioxidants, Spectra-Syn Plus PAO can be formulated to resist thermal oxidative attack. 4 0 obj <> endobj PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. Polyalphaolefins also have poor fire resistance and biodegradability. Specific heat is the amount of heat per unit mass required to raise the temperature one degree Celsius. These compounds are not discernable in Synfluid PAOs. Approximately 80% of synthetic lubricants used in the world are of three types. Research at the U.S. polyalphaolefin compatibility chart. endobj 0000002192 00000 n This Chemical Compatibility Guide is offered for informational purposes only and was developed from information sources other than SpillTech.

Process Chemical Compatibility Guide These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile. For instance, a 100 percent aminic antioxidant package will yield the best performance in the Rbot test for PAO. The chart below shows rotary bomb (ASTM D2272) results between Synfluid PAOs and some mineral oils. Their polymerization can benefit greatly from the development of highly active and highly selective catalysts, as the catalysts strongly affect their properties. This new system improves the viscosity properties, which should be more energy conserving and achieves the ultimate biodegradation rating ASTM D5864-PW1. Chemical kinetics tell us that if you reduce the temperature, you will reduce the reaction rate. We expect that specifications for driveline fluids will continue to tighten due to pressure from energy conservation, improved transmission design and fluid longevity. Blending lower-quality base oils into this formulation would compromise the passing mark. Address specific system site conditions (potential for water ingression). The viscosity of the base oil is largely irrelevant in relation to the compatibility risks with the thickener. 232 0 obj Let us help you.

Group IIIB was unable to consistently pass the TDI or M111 tests. 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. There are emerging markets that demand the improved VI and volatility that only the C12-based PAOs can deliver. The information listed in parentheses is D-1418 nomencalture, common acronyms or common trade names. Lack of mineral oil solubility is a barrier to expanded use of PAG-based lubricants. Ethylene is produced by cracking either crude oil or natural gas. xmp.id:B2FC01B10F2068118083E936383AAE83 Chemical Compatibility Guide Since we are all concerned with the protection of our environment, it is important to note some PAOs can be formulated with other components into biodegradable fluids. 0000161878 00000 n 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. Because metalworking processes can generate heat, these properties give you an intrinsic safety margin over the more volatile oils that are typically used. The qualitative chart below describes the impact of each grease component on certain performance characteristics: Clearly, the base oil dominates some grease properties, while the additives or thickener drives others. 2013-07-10T14:05:23-05:00 Use of WGHFs increased tremendously due to the publication of the Luxembourg Report in 1961, outlining minimum standards for hydraulic fluid fire-resistance in European coal mines. 10.1 Introduction. However, VI doesnt tell the whole story it only reflects the viscosity/temperature relationship between 40C and 100C. Furthermore, these new formulations allow a range of ISO viscosity grades. California Transparency in Supply Chains Act Disclosure. Aviation hydraulics require the use of PAOs because of the inherently high flash/fire points and low volatility. Our sustainability strategy encompasses the concerns and issues identified by our stakeholders and we are committed to addressing these issues. 0000162168 00000 n The more EO monomer in the basestock, the more water-soluble; the more PO monomer, the more water-insoluble; and the more BO monomer, the more oil-soluble the basestock is. Its estimated that over 100 million gallons of fluids leak from hydraulic machinery and other lubricant equipment in North America each year! PAO- and PAG-based lubricants are both hydrolytically stable and have low pour points. The 2002 U.S. Farm Bill Act mandates government agencies to purchase environmentally safe, biobased (vegetable oil) lubricants. Challenges like these truly reveal the performance advantages of Synfluid PAOs. The uniquely beneficial quality of PAOs has been demonstrated in a series of European engine tests. 0000001605 00000 n uuid:df0b74fe-2082-ca4e-860d-fb6b88ddfe4d BioPreferred is a registered service mark of the United States Department of Agriculture. Not Available - Chemical compatibility information is not available at this time. One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. From then on, the company introduced 1-dodecene-based PAOs in 1995, which have grown steadily in popularity. These advantages are achieved without the need for VI improvers or other additives, which may promote other deleterious effects as they degrade. In a comparison of gear lubricants, PAOs reduced the effective operating temperature by as much as 10 20C. Heavier components adversely affect low-temperature performance and pour point. Thats a hot topic! 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. After the formation of the Chevron Phillips Chemical joint venture in 2000, a 10 KTA PAO unit expansion followed soon thereafter. Copyright 2023 Chevron Phillips Chemical Company LLC. However, Group III base stocks are derived from multiple feedstock choices and processing technologies, which create variability in the properties. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. 0000135087 00000 n Whichever low-viscosity base oil is used, it must exhibit viscosity stability and low volatility. For instance, excellent water separation improves compressor operability by reducing the chance of emulsion formation. 4e739735ec50523ad929b6aac8340ae467185943 The vast number of high-quality base oil choices can be confusing when balancing fuel efficiency and wear protection. 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. End-users must first select a lubricant based upon its intended application, such as engine oil, transmission oil, hydraulic oil, wire rope lubricant, electric motor grease, etc. DuPont, the DuPont Oval Logo, and all trademarks and service marks denoted with , or are owned by affiliates of DuPont de Nemours, Inc. unless otherwise noted. We believe that it is possible to achieve a passing mark with even lower amounts of PAO, further reducing costs.
