To correctly identify what type of fluid is needed, the end-user must know the minimum lubricant requirements for that piece of equipment. PAOs also resist viscosity increases upon oxidation, which is important in sequence IIIE and VW T4 engine tests. PAG-based lubricants have excellent viscosity indices significantly better than PAO-based lubricants of the same viscosity grade. High energy costs have hit both businesses and consumers hard, and the pressure is on to conserve. The term synthetic hydrocarbon (SHC) is a general term. PAG polymers, first discovered more than 150 years ago, saw their breakthrough application occur during World War ll. 11 46 0000000416 00000 n PDF CHEMICAL RESISTANCE CHART - U.S. Plastic CHEMICAL RESISTANCE CHART. The trend falls short when comparisons are made between PAOs and mineral oils, based solely on the VI. 0000017608 00000 n California Transparency in Supply Chains Act Disclosure. Each lubricant type will be the best choice for different sets of use parameters, including: PAO-based lubricants may be preferred when the following lubricant attributes are targeted: PAG-based lubricants may be preferred when the following lubricant attributes are targeted: If end-users are in doubt about which lubricant would best suit their needs, it is recommended that an expert be contacted to assist with the decision-making process. Ethylene glycol dimethacrylate is the enoate ester that is the 1,2-bis (methacryloyl) derivative of ethylene glycol.

PAOs are the most common synthetic basestock used in industrial and automotive lubricants. These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile. Aluminum is compatible with fluids such as polyalphaolefin (PAO), oil, ethylene glycol and water solutions (EGW), as well as Fluorinert, an electrically insulating inert perfluorocarbon fluid manufactured by 3M and used in many electronics cooling applications. D = Severe Effect, not recommended for ANY use. 0000042568 00000 n Adding a PPD will reduce the pour point of a mineral oil, but it still will not achieve the performance of a PAO. 2013-07-10T14:05:23-05:00 0000002388 00000 n PAG- and PAO-based lubricants rarely compete in industrial applications. esters or alkylated naphthalenes) to improve their solvency and deposit control. Fluids are typically subjected to various shear and temperature conditions. polyalphaolefin compatibility chart. P.V.C. While viscosity improvers can enhance VI, they can break down over time, resulting in diminished performance. The uniquely beneficial quality of PAOs has been demonstrated in a series of European engine tests. One obvious trend is that low-viscosity oils are beneficial in improving fuel efficiency. %PDF-1.4 % 0000036029 00000 n 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. The VI trend is only true for a family of base oils. As the chart above clearly demonstrates, the difference in viscosity as a function of shear rate is magnified as temperature decreases. There can be many benefits from choosing a high VI base fluid. 2 shows the flow chart for producing Cu nanolubricants. Give us a call, and well be glad to discuss your applications and provide technical help. Focusing on the components of the additive package can further influence the performance of the formulation.

PAO quality is unrivaled in the industry. . In our experience, some commercially available additive packages are designed to take better advantage of a specific base stock. General properties of low- and high-viscosity conventional PAO, and metallocene-catalyzed mPAO basestocks, are shown in Table 4. However, moving to lower-viscosity oils is a possibility only if you can maintain a low Noack volatility for emissions control and lubricant stability. Synfluid PAOs, in addition to NSF H1 qualification, are also available as kosher approved products. For instance, many producers have tailored production to Group II+ stocks at 118119 VI, just below the ambiguous Group III limit of 120VI. Available on demand until February 16, 2024. This is compared to a conventional hydraulic fluid in the chart below. In contrast, a mineral oil will require various antioxidants depending upon the structural makeup. hence, compatibility with base-oil molecules like PAO oil is improved. Chemical Compatibility Guide The grease is then inspected for visual abnormalities and can be tested for penetration and four-ball wear change. The lighter components cause poorer volatility properties as well as lower flash and fire points. 0000000891 00000 n 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. uuid:df0b74fe-2082-ca4e-860d-fb6b88ddfe4d Low molecular weight compounds will degrade other performance requirements, such as volatility, flash and fire points. Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants. Chevron Phillips Chemicals Synfluid mPAO 65, 100 and 150 cSt products have very high viscosity indices and lower pour points than other HV PAO products. PPDs act only on linear or waxy compounds, and these characteristics are absent from PAOs. 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. 0000161810 00000 n '0v^ Ln 1qDP]C[,z[v(u_g.Fh{K>8rI,[GV&mE}^ 9S87PGgT hO"4=]3JVp ZmU[@=ocLV]P *y`# dY'!3!IP0O. We make the petrochemical solutions found in products of all kinds with purpose, collaboration and care. The magnitude of these benefits will depend on the particular formulation. Using the same PAO, we achieved 15 percent higher oxidative stability by increasing the A.O. 0000002192 00000 n 0000035588 00000 n 0000004340 00000 n These compounds are not discernable in Synfluid PAOs. PDF PAO chart - Radco Ind 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. 2014-03-26T09:16:41-05:00 This is the case for blending Synfluid PAO 5 and PAO 7. hb```b``nd`c``. endobj Two lubricants with the same VI may perform dramatically differently at low temperatures. 0000035336 00000 n The PAOsare produced through synthesizing oligomers of either 1-decene or 1-dodecene. endobj First, dont touch the gear box; you will burn your hand. The Scanning Brookfield chart on this page demonstrates the difference in viscometrics between a Synfluid PAO and a pour point depressed mineral oil. Adobe PDF Library 10.0.1 As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. Synfluid PAOs also have a very high degree of saturation, which in lubricants provides oxidative stability. PAOs on the other hand are derived from a clearly defined processing technology using petrochemically pure alpha olefins. Chemical Compatibility Chart | ISM - Industrial Spec From then on, the company introduced 1-dodecene-based PAOs in 1995, which have grown steadily in popularity. The degree of the advantage may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). As a result, the jump in the viscosity adversely effects the ability to pump at low temperatures. Glad you asked! Grease is a solid to semi-fluid lubricant, typically used for difficult to service equipment, such as bearings or suspension systems. Chevron Phillips Chemical has been producing two families of PAOs for close to 25 years. Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. PAG- and PAO-based lubricants are used in multiple industries and, as synthetics, offer improved performance over mineral oils. Due to constraints with the supply of 1-decene, the traditional feedstock for PAOs, producers have experimented with alternative feedstocks to meet demand. Satisfactory to 72F (22C) 2. 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. However, Synfluid PAOs can be formulated to be biodegradable and are well known for standing out from conventional base oils. They're found in everyday food and available as supplements. A polyolefin is a type of polymer with the general formula (CH 2 CHR) n where R is an alkyl group. Tiny bubbles these can cause major issues, such as shorter lubricant life, increased fluid compressibility, lower fluid viscosity and cavitation.
