Polyglycols-40 to 125 C Synfluid PAOs are qualified as technical white oils (per 21 CFR 178.3620(b)(1)) due to their clear, bright color and exceptional UV properties. <> For other applications, PAOs safe and non-toxic nature allows them to be used where incidental food contact certification or kosher approval is necessary. A run through the test: Chevron Phillips Chemical has been producing two families of PAOs for close to 25 years. These 1-dodecene-based products (Synfluid 2.5, 5, 7 and 9cSt PAOs) are now recognized to have superior performance in their own applications. Use this chart to help guide your component selection. Chemical Compatibility Guide 0000162168 00000 n General properties of low- and high-viscosity conventional PAO, and metallocene-catalyzed mPAO basestocks, are shown in Table 4. Synfluid PAOs, in addition to NSF H1 qualification, are also available as kosher approved products. Polyalkylene glycol (PAG) and polyalphaolefin (PAO) are two synthetic lubricant options for industrial applications. 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. 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. 0000017608 00000 n A solution, developed by Renewable Lubricants Inc. (RLI) with assistance from Chevron Phillips Chemical, is the use of Synfluid PAOs combined with biobased oils and specially designed additives. For example, the fraction that has predominantly the 1-decene trimer (C30 oligomer) has a 100C viscosity of 4 cSt and is known as PAO 4. PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. 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. With many new base oils being introduced to the market, lubricant consistency can really be a challenge. PAG-based lubricants provide many property and performance advantages over mineral oil-based and other synthetic lubricants, as outlined in Table 2. The remaining synthetic lubricants are produced from other basestocks, including phosphate esters, polybutenes, silicones, perfluoroalkyl, and polyphenyl ethers. Synfluid PAOs are crafted from an on-purpose process that yields a consistent, high-quality product. 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. Our C10-based products, commercialized in the 1970s, were the first in the market. The chart differentiates the blending capabilities of various base oils to meet energy-efficient motor oils. The rotary bomb bench test is a strong predictor of how base oils will perform in many automotive and industrial applications. PAO quality is unrivaled in the industry.

This article will discuss the most common synthetic fluids aiming to help end-users make the right choice for their applications. The most favorable performance is achieved by using the highest-quality base oils. 89 0 obj 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.). Not necessarily. concentration from 0.5 percent to 1 percent. This is one clear benefit of using a carefully designed base oil. Of course, and your options are growing! While viscosity improvers can enhance VI, they can break down over time, resulting in diminished performance. June 16, 2022; Posted by usa volleyball national qualifiers 2022; 16 . Well be happy to help you solve your lubricant concerns. Two lubricants with the same VI may perform dramatically differently at low temperatures. However, VI doesnt tell the whole story it only reflects the viscosity/temperature relationship between 40C and 100C. In addition to these properties, weve also seen a significant reduction in the traction coefficient as compared to conventional high-viscosity PAOs. Fluids are typically subjected to various shear and temperature conditions. 0000016208 00000 n The VI trend is only true for a family of base oils.

Were here to help. MOLYKOTE. 0000162144 00000 n Synfluid PAOs have very narrow molecular weight ranges, which are attributed to our high-purity feedstocks. Chemical Compatibility Guide Absolutely! 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. Please dont hesitate to reach out to us if you have any questions! The effects of the shear rate differences are even more exaggerated at low-temperature startup conditions, when the lubricant function is critical for equipment protection. Both the foam tendency (the initial amount of foam generated in this test) and the time required for the foam to collapse are remarkably better for Synfluid mPAO. Specific heat is the amount of heat per unit mass required to raise the temperature one degree Celsius. Because metalworking processes can generate heat, these properties give you an intrinsic safety margin over the more volatile oils that are typically used. 0000017423 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. PAOs are considered a very pure substance since they are derived from petrochemically pure ethylene and then from 1-decene or 1-dodecene, which could be considered a further purification step. endobj However, PAGs and PAOs are two totally different chemical types of synthetic base stocks. Some of the advantages of PAO-based lubricants are summarized in Table 5. package, an optimal PAO formulation will be different than that of mineral oils. Sorry, you need to enable JavaScript to visit this website. Since PAO fluids are synthetic hydrocarbons, they are compatible with and often combined with mineral-based oils. Our C12-based grades further improve flash/fire points by as much as 10 percent over other commercial polyalphaolefins.

As an example of the improved low-temperature torque properties of the PAO-based grease, the chart below shows torque values for Chemtools CSC 980 grease under ASTM D 4693 test conditions for rotation of a wheel-bearing assembly at -40C. A relatively simple test, the criteria of the test varies depending on which grease manufacturer you are dealing with. trailer Although VI is an important indicator, when used alone, VI is misleading. 93 0 obj While pour point is one consideration, a formulator has to take into account the total specification needs. As temperature decreases, a higher VI fluid will have reduced viscous drag, which could lead to higher horsepower and energy efficiency. Our customers quickly realized the advantages in volatility, low-temperature viscometrics, VI and flash and fire points in equiviscous blends compared to 1-decene-based materials. endobj BioPreferred is a registered service mark of the United States Department of Agriculture. 0000135615 00000 n As a result, the jump in the viscosity adversely effects the ability to pump at low temperatures. The chart below illustrates the relative effect base oils have on the operating temperatures in a modified four-ball machine. Unlike other industrial basestocks, PAOs are generally classified by their kinematic viscosity at 100C. Satisfactory to 72F (22C) 2. <> There are distinct advantages in volatility and low-temperature viscosity. PAOs derived from 1-dodecene can improve many properties, including volatility. This is a recurring situation and is what led to the development of 1-dodecene based Synfluid PAOs in 1995. The properties mentioned above are in addition to the normally excellent performance you have come to recognize with PAO. Polyalkylene glycol (PAG) and polyalphaolefin (PAO) are two synthetic lubricant options for industrial applications. 0000001726 00000 n Satisfactory to 72 F. 3.

P.V.C. 0000036701 00000 n 0000161553 00000 n These combined benefits provide the properties required for severe service applications and extended drain intervals. The ability of a lubricant to reach critical metal-to-metal interfaces in a gear system can be the difference between operation or shutdown. xmp.did:F87F1174072068118083E936383AAE83 0000004079 00000 n Tiny bubbles these can cause major issues, such as shorter lubricant life, increased fluid compressibility, lower fluid viscosity and cavitation. Since they are fully synthetic, Synfluid PAOs are extremely pure and provide inherent benefits in oxidative stability and viscosity performance at temperature extremes. The higher the coefficient, the greater the change in viscosity at elevated pressures. Furthermore, the process is a simpler, more energy-efficient route for grease production. This Chemical Compatibility Guide is offered for informational purposes only and was developed from information sources other than SpillTech. Chemical Compatibility Guide Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. PAOs are uniquely suited to aviation hydraulics because of the inherently high flash/fire points and low volatility. While typical hydraulic oils are not biodegradable, this new system achieves the ultimate biodegradation rating (ASTM D5864 PW1) and even improves several performance parameters, not previously attainable. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 159 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> From then on, the company introduced 1-dodecene-based PAOs in 1995, which have grown steadily in popularity. Effect of Base Oil Type on Gear Box Temperatures. %%EOF 11 46 As oil volatilizes, the viscosity increase will result in poorer overall performance. The lower volatility decreases oil replacement costs by reducing oil consumption. A Group III mineral oil with a 0.1 percent PPD achieves an improved pour point, but to the detriment of the low-temperature viscometrics. The second step is the hydrogenation of the remaining double bonds (unsaturation) in the oligomer and subsequent distillation to separate the unreacted monomer and light-viscosity grade PAO. This formulation achieved a 13% benefit when the PAO was directly substituted with Synfluid PAO. Chemical Compatibility Guide Adobe InDesign CS6 (Macintosh) False Our sustainability strategy encompasses the concerns and issues identified by our stakeholders and we are committed to addressing these issues. PAOs offer exceptionally low volatility due to their controlled formation, which yields carefully designed molecular weights.
