PAOs also resist viscosity increases upon oxidation, which is important in sequence IIIE and VW T4 engine tests. 0000017423 00000 n These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile. In the chart below, we highlight how moving from a decene-based Synfluid PAO 6 to an iso-viscous dodecene-based fluid (resulting from a blend of PAO 5 and PAO 7) leads to a dramatic increase in VI. MOLYKOTE. PAOs are Newtonian fluids; in other words, their viscosities are fairly independent of shear rate. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. When unsure of a components precise identity or version, the manufacturer Leaking fluids from equipment used in sensitive geographical areas can have long-term negative consequences on the environment. The uniquely beneficial quality of PAOs has been demonstrated in a series of European engine tests. This is a far greater benefit than can be achieved from other base oils. Furthermore, the advantages of exceeding the minimum requirements for driveline fluids will enhance the benefits of the finished lubricant. Adobe InDesign CS6 (Macintosh) endobj 0000041967 00000 n Typically, as the viscosity drops, the volatility increases. %%EOF PAG- and PAO-based lubricants are used in multiple industries and, as synthetics, offer improved performance over mineral oils. D = Severe Effect, not recommended for ANY use. Chevron Phillips Chemical offers two lines of PAOs. The C12-derived PAOs were created to give better volatility, giving formulators four new options when choosing PAOs. 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. <> Give us a call, and well be happy to discuss our high-quality Synfluid PAOs with you. Thats a hot topic! In addition to the low temperature performance demonstrated by CCS, the volatility and viscosity index of the PAO 5 and 7 blend are improved over traditional PAO 6. 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. Polypropylene Satisfactory to 120 F. 4. In these extreme services, a PAO-based lubricant is able to reach the area that requires lubrication and prevent damage or wear. In addition to meeting current limits, a lower viscosity will reduce energy consumption. Approximately 80% of synthetic lubricants used in the world are of three types.

Some of the advantages of PAO-based lubricants are summarized in Table 5. To improve fuel economy, OEMs are moving toward lower-viscosity oils, even in heavy-duty diesel engines. However, PAGs and PAOs are two totally different chemical types of synthetic base stocks. With many new base oils being introduced to the market, lubricant consistency can really be a challenge. And we pioneered and patented our unique C12-based PAOs in the 1990s. 93 0 obj LDPE Chemical Compatibility Chart - calpaclab.com Polyalkylene glycol (PAG) and polyalphaolefin (PAO) are two synthetic lubricant options for industrial applications.

Chemical Compatibility Guide; what chemicals to use; guide for chemical uses; general guideline for pump material selection; material chemical compatibility As the chart below shows, greater energy efficient, lower viscosity oils can be made through the selection of PAO, without sacrificing volatility. Bk.2z3)))lBShBSX!D !DOaBBB*=]!z Furthermore, the arbitrary distinction of 120 VI between Group II and III oils makes the quality requirements even more confusing. Actions. Synthetic basestocks, more so than in mineral oil basestocks, are the primary contributor to most of the basic properties of the lubricant, including oil or water solubility, low-temperature fluidity, lubrication, volatility, ignitability, and seal and paint compatibility. PDF Synthetic Oil Viscosity & Compatibility Chart - DULUB After all, the reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. What is most interesting, however, is the low-temperature performance: The C10-based PAO 6 has the lowest pour point by over 20C, but the CCS viscosity for the C12-based PAO 5 and 7 blend is better. 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. PDF Chemical Resistance Guide - Gilson Eng Metallocene-catalyzed commercial mPAO basestock grades can attain a viscosity of 300 cSt at 100C. Reasons to change from mineral oil-based lubricants to synthetics despite the increase in cost include: Advances in equipment technology have resulted in more demanding lubricant conditions and requirements, many beyond the capabilities of mineral oil-based lubricants. There are distinct advantages in volatility and low-temperature viscosity. The limits on lowering the viscosity grade are tied to the base oil properties. As the chart above shows, lower-viscosity oils can be made without sacrificing low volatility by using PAO base oils.

PDF Chemical Compatibility Guide - Graco endstream Galvanized steel is susceptible to attack by some chemicals which may cause . endstream endobj 8 0 obj <>stream In terms of viscosity, there are tradeoffs in choosing one PAO over another: energy consumption (heat dissipation and production throughput) versus safety of operations (impacted by flash/fire points and volatility). If a polyurea-based thickener is chosen in conjunction with a synthetic base oil, such as a polyalphaolefin (PAO), there is no compatibility risk to be expected. We have measured a 25 percent improvement in oxidation induction times simply by decreasing the test temperature by 10 degrees. 0000000416 00000 n Nine standard circulating fluids including d-Limonene, FC77 Flourinert, Galden, Lexol 408, Paratherm CR, Coolanol and PAO. There are many advantages! The relative availability of olefin monomer was certainly a consideration (i.e., 1-octene vs. 1-decene). There are other advantages, such as oxidative and thermal stability, which you would naturally expect from a PAO-based product. The chart differentiates the blending capabilities of various base oils to meet energy-efficient motor oils. %PDF-1.4 % 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. Satisfactory to 72 F. 3. The PAOs . The latest news, content and events about our company, initiatives, markets and products. 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. Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants. Temp. Working in conjunction with the Union Carbide Chemicals, Plastics Company Inc., and the Mellon Institute of Industrial Research, the USNRL developed the first water-glycol, PAG-thickened, fire-resistant hydraulic fluid (WGHF). 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. Buna-N Satisfactory for "O . In addition to these properties, weve also seen a significant reduction in the traction coefficient as compared to conventional high-viscosity PAOs. The lower volatility decreases oil replacement costs by reducing oil consumption. in extreme environments and to avoid plastic and elastomer compatibility problems. To improve seal compatibility of PAO-based lubricants, an ester is added to the formulation to add some polarity. Since then, the company has expanded PAO as well as ethylene production, both basic building blocks for many petrochemical processes. As pressure increases, so too does the viscosity of the lubricant. endobj In contrast, the Synfluid PAO formulation achieves a pass with as little as 30 percent PAO, the balance being Group I mineral oil. Level of maintenance and labor available. Synfluid mPAOs exhibit faster air release times, particularly when comparing the 100 cSt blends.
