Give us a call, and well be glad to discuss your applications and provide technical help. Chevron Phillips Chemical has consistently said that we would bring something to the market when we could provide products that are unique and offer advantages to our customers. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. The properties mentioned above are in addition to the normally excellent performance you have come to recognize with PAO. !DOaBADOaB&=&=U!z They are usually derived from a small set of simple olefins ( alkenes ). 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. The Scanning Brookfield chart on this page demonstrates the difference in viscometrics between a Synfluid PAO and a pour point depressed mineral oil. 169 0 obj 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. Address new equipment conditions (higher operating temperature and pressure, greater loads and speed). 0000042568 00000 n Synfluid PAO improves finished lubricant performance when formulated into biodegradable and biobased lubricants in low-temperature viscometrics and oxidative stability. esters or alkylated naphthalenes) to improve their solvency and deposit control. Getting the air to release from the lubricant is vital to allowing the lubricant to do its job. We were the first to offer these materials to the marketplace, and many years of experience with 1-dodecene-based PAOs has helped us to refine the process and deliver very high-quality products. 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. 3 !1AQa"q2B#$Rb34rC%Scs5&DTdEt6UeuF'Vfv7GWgw ; !1AQaq"2B#R3$brCScs4%&5DTdEU6teuFVfv'7GWgw ? More importantly, however, was product performance. Chemical kinetics tell us that if you reduce the temperature, you will reduce the reaction rate. 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. 0000000891 00000 n As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. Satisfactory to 72F (22C) 2. endstream 0000003482 00000 n While pour point is one consideration, a formulator has to take into account the total specification needs. Driveline specifications continue to become more stringent. There can be many benefits from choosing a high VI base fluid. <> 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. in extreme environments and to avoid plastic and elastomer compatibility problems. 4e739735ec50523ad929b6aac8340ae467185943 Polyolefins, including poly (ethylene), poly (-olefin), poly (styrene), and poly (dienes), are the most widely-used polymer materials.

CHEMICAL RESISTANCE CHART. 0000001605 00000 n However, VI doesnt tell the whole story it only reflects the viscosity/temperature relationship between 40C and 100C. 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 choice of C10- or C12-derived PAO depends on the application and/or specification requirements. Certainly! Based on recent average gas prices, conserving just 1% to 2% of the U.S. fuel consumption per year would save $14 million per day. Refined mineral oils often contain sulfurs, aromatics and other compounds that can erode the quality and consistency of a mineral oil. They are also employed as base fluids in some wide temperature range greases. and PAO plays an integral part of meeting the challenge for top-tier oils. Great question! The chart below shows the trends in industry specifications regarding low-temperature performance relative to Synfluid PAO. Blending lower-quality base oils into this formulation would compromise the passing mark. Polyolefin. There are other advantages, such as oxidative and thermal stability, which you would naturally expect from a PAO-based product. 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. Since there are no other discernable compounds, Synfluid PAOs are more readily biodegradable and can be used for some food applications. endobj Copyright 2023 Chevron Phillips Chemical Company LLC. More uniform in structure than conventional PAO basestocks, they provide similar advantages of high viscosity indices, excellent low-temperature fluidity, and shear stability but with additional thickening ability. Polypropylene Satisfactory to 120 F. 4. Having a high viscosity index helps to protect an engine at temperature extremes. But what happens below 40C? If a certain application can sacrifice a 10 15C increase in the pour point, then there is as much as a 25% improvement in volatility, as shown in the chart below. Buna-N Satisfactory for "O . 0000048689 00000 n According to the U.S. government, biobased is defined as at least 44% biobased carbon content for hydraulic fluids. polyalphaolefin compatibility chart Posted by . <> In addition, a PAO-based multi-purpose grease can be formulated to be both H1 and kosher approved. xmp.did:00801174072068118083E936383AAE83 93 0 obj 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.

Later used in many industrial applications from compressor, hydraulic, and turbine fluids to gear oils and metalworking fluids. Furthermore, the process is a simpler, more energy-efficient route for grease production. hb```f``g mBU L4#o0 D xref Additionally, PAOs have high viscosity indices, which lead to less film thickness reduction at elevated temperatures. There are multiple formulations behind the science of synthetic lubricants that can complicate making the right choice for any application. Chemical Compatibility Guide Dominant in a commercial sense are polyethylene and polypropylene. This new system improves the viscosity properties, which should be more energy conserving and achieves the ultimate biodegradation rating ASTM D5864-PW1. 0000027693 00000 n To improve fuel economy, OEMs are moving toward lower-viscosity oils, even in heavy-duty diesel engines. PAO-based greases are typically used at temperatures over 100C because of thermal and oxidative concerns. PAG-based lubricants are commonly used in compressors, gearboxes, air conditioning systems, metalworking, quenching, and hydraulic systems where fire-resistance or environmental acceptability are required. startxref 0000000016 00000 n For example, one would not be able to make an 0W-20 oil with a C12-derived PAO as the viscosities are too high. The VI of PAOs typically only varies one to two points. Whether its transportation or industrial lubes, greater fuel efficiency means lower operating costs. 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. These advantages show that PAOs address problems other fluids cannot.
