It is possible to get added property benefits from C12-based Synfluid PAOs. <> 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). In a comparison of gear lubricants, PAOs reduced the effective operating temperature by as much as 10 20C. Actions. The key to unlocking the full potential of your formulation requires using the right combination and concentration of antioxidant and Synfluid PAO. PAOs are Newtonian fluids; in other words, their viscosities are fairly independent of shear rate. Specifically, soybean-derived oils or other bio-derived oils alone would not meet some oxidative stability and low-temperature performance requirements. However, moving to lower-viscosity oils is a possibility only if you can maintain a low Noack volatility for emissions control and lubricant stability. Some claim the Viscosity Index (VI) is the overriding parameter used when choosing a base oil. As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. Finally, due to their excellent response to antioxidants, Spectra-Syn Plus PAO can be formulated to resist thermal oxidative attack. PAOs derived from 1-dodecene can improve many properties, including volatility. Satisfactory to 120F (48C) Ratings: Chemical Effect A = Excellent. There are other advantages, such as oxidative and thermal stability, which you would naturally expect from a PAO-based product. Meet new original equipment manufacturer and industry standard requirements. Disadvantages of PAG-based lubricants are summarized in Table 3. 0000034289 00000 n Chevron Phillips Chemical has been producing two families of PAOs for close to 25 years. The lower volatility decreases oil replacement costs by reducing oil consumption. The vast number of high-quality base oil choices can be daunting when trying to balance fuel efficiency and wear protection. 304 Stainless Steel Chemical Compatibility Chart ver 28-Oct-2022 Key to General Chemical Resistance - All data is based on ambient or room temperature conditions, about 64F (18C) to 73F (23C) A = Excellent C = Fair - Moderate Effect, not recommended And we pioneered and patented our unique C12-based PAOs in the 1990s. Bk.2z3)))lBShBSX!D !DOaBBB*=]!z 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. This is one clear benefit of using a carefully designed base oil. Lower-viscosity PAOs have a unique property of biodegradability. False 0000017423 00000 n This new system improves the viscosity properties, which should be more energy conserving and achieves the ultimate biodegradation rating ASTM D5864-PW1. Several synthetic base oil types fall into the SHC category. 0000161878 00000 n These products are acceptable for use as a lubricant (H1) or as a lubricant component (HX-1), with incidental food contact in and around food processing areas. PAG polymers, first discovered more than 150 years ago, saw their breakthrough application occur during World War ll. These properties translate into easier distribution of the grease and improved energy efficiency in the equipment. guide for chemical uses More importantly, however, was product performance. Temp.

They may also be used to develop high-performance, environmentally friendly lubricants. 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. BioPreferred is a registered service mark of the United States Department of Agriculture. Entergy Grows Revenue, Increases Customer Satisfaction with Value-Added Services, Flexible & Reliable: Optimal performance amid variable power generation, AI in Renewables: The Secrets to Successfully Scaling a Diversified Fleet. PAOs help to balance the protection and energy conservation requirements in equipment because they are more Newtonian than mineral oils. Polyphenols are a complicated group of plant-based chemicals. We expect that specifications for driveline fluids will continue to tighten due to pressure from energy conservation, improved transmission design and fluid longevity. A polyolefin is a type of polymer with the general formula (CH 2 CHR) n where R is an alkyl group. Group V oils also include esters and naphthenic oils. Tiny bubbles these can cause major issues, such as shorter lubricant life, increased fluid compressibility, lower fluid viscosity and cavitation. CHEMICAL RESISTANCE CHART. 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. Since this can be achieved without sacrificing hydrolytic stability, the finished lubricant will maintain superior properties over an extended period of time, resulting in less waste. One example is the advantage PAO has over mineral oil in the area of high-temperature stability. One application in which they have not worked well is in high-temperature (high-pressure) reciprocating air compressors where valve deposits have been an issue. / Therefore, they are commonly blended or combined with organic ester synthetic base oils to provide a blended base oil that does not have these negative characteristics. Technical White Oils are approved for incidental food contact at USDA-approved meat and poultry plants. Some of the advantages of PAO-based lubricants are summarized in Table 5. For instance, excellent water separation improves compressor operability by reducing the chance of emulsion formation. For instance, many producers have tailored production to Group II+ stocks at 118119 VI, just below the ambiguous Group III limit of 120VI. 4 0 obj <> endobj The table below shows how our new Synfluid mPAOs offer significant advantages in pour point and viscosity index over conventional high-viscosity PAOs. PAG lubricant basestocks can be designed to be water-soluble, water-insoluble (partial mineral oil compatibility), or oil-soluble, depending on the selection of starter molecules and monomers to be used in producing the polymer. 0000162168 00000 n The rotary bomb bench test is a strong predictor of how base oils will perform in many automotive and industrial applications. The price of Polyalphaolefin (PAO) has been steadily decreasing throughout the third quarter of 2022 on the back of the poor performance of the downstream automotive sector in the continent.

The relative availability of olefin monomer was certainly a consideration (i.e., 1-octene vs. 1-decene). Furthermore, these new formulations allow a range of ISO viscosity grades. The combination of air and oil can often lead to foaming issues. This lowers their volatility, creates less hydrocarbon tailpipe emissions and raises the flash point. We make the petrochemical solutions found in products of all kinds with purpose, collaboration and care. However, VI doesnt tell the whole story it only reflects the viscosity/temperature relationship between 40C and 100C. This clearly shows that a PAO base oil substitution can significantly lower operating temperatures of the gear box and extend the required maintenance interval. 0000003221 00000 n We are first in your inbox with the most important news in the industry―keeping you smarter and one-step ahead in this ever-changing and competitive market. 0000001764 00000 n However, these products have demonstrated unique advantages in Sequence IIIF, VW T4 and TDI tests due to many of the other properties that are inherent in them. The VI of PAOs typically only varies one to two points. A product developed by Renewable Lubricants Inc. (RLI), with assistance from Chevron Phillips Chemical, uses Synfluid PAOs combined with biobased oils and specially designed additives. In addition to these properties, weve also seen a significant reduction in the traction coefficient as compared to conventional high-viscosity PAOs. Oxidative and other lubricant degradation mechanisms would follow the same trend. Due to constraints with the supply of 1-decene, the traditional feedstock for PAOs, producers have experimented with alternative feedstocks to meet demand. package, an optimal PAO formulation will be different than that of mineral oils. trailer <<1656AD0EDA344239AE3641B5710538C3>]/Prev 1036271>> startxref 0 %%EOF 296 0 obj <>stream endobj As the chart above shows, lower-viscosity oils can be made without sacrificing low volatility by using PAO base oils. The degree of the advantage may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). In the past three years, European specifications for volatility and oxidative stability have become significantly more stringent. Thermal conductivity is the measure of the ability to conduct heat. These advantages are achieved without the need for VI improvers or other additives, which may promote other deleterious effects as they degrade. polyalphaolefin compatibility chart.
