Since we use essentially pure 1-decene or 1-dodecene to produce Synfluid PAOs, there is a narrow isomeric distribution for each oligomer. Fluid distribution panels are also discussed. The most favorable performance is achieved by using the highest-quality base oils. We have measured a 25 percent improvement in oxidation induction times simply by decreasing the test temperature by 10 degrees. This will increase the dependence on high-quality base oils such as PAOs. 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. So you can look to Synfluid PAO to help you formulate lubricants with both environmental benefits and outstanding performance properties. PAG polymers, first discovered more than 150 years ago, saw their breakthrough application occur during World War ll. 0000000891 00000 n To improve seal compatibility of PAO-based lubricants, an ester is added to the formulation to add some polarity. The remaining synthetic lubricants are produced from other basestocks, including phosphate esters, polybutenes, silicones, perfluoroalkyl, and polyphenyl ethers. PAO SYNTHETIC MATERIAL COMPATIBILITY CHART This table is aids in the selection of elastomers, plastics and paints for use in conjunction with PAO synthetic fluids. These combined benefits provide the properties required for severe service applications and extended drain intervals. As the chart above shows, lower-viscosity oils can be made without sacrificing low volatility by using PAO base oils. Process Chemical Compatibility Guide !DOaBADOaB&=&=U!z Furthermore, the arbitrary distinction of 120 VI between Group II and III oils makes the quality requirements even more confusing. No matter what the combination of additive or base oil, one thing is certain: When you begin with a higher-quality base oil, you will achieve a better formulation in the end. CHEMIC ATIBILITY 3 Updated 7/2/13 CHEMICALS METALS PLASTICS, ELASTOMERS & LEATHER A: Excellent, B: Good, C: Fair to Poor, D: Not recommended Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene. These include the tendency to shrink seals and trouble dissolving common oil additives. Disadvantages of PAG-based lubricants are summarized in Table 3. polyalphaolefin compatibility chart. 4e739735ec50523ad929b6aac8340ae467185943 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. Available on demand until February 16, 2024. Business never stands still, but you can always count on dependable Chevron Phillips Chemical Synfluid PAOs. Polyalphaolefins also have poor fire resistance and biodegradability. 97 0 obj 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. Our C10-based products, commercialized in the 1970s, were the first in the market. There are many advantages! These are areas where PAOs excel. Its estimated that over 100 million gallons of fluids leak from hydraulic machinery and other lubricant equipment in North America each year! Because metalworking processes can generate heat, these properties give you an intrinsic safety margin over the more volatile oils that are typically used. LDPE is defined by a density range of 0.910-0.940 g/cm3. 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. We expect that specifications for driveline fluids will continue to tighten due to pressure from energy conservation, improved transmission design and fluid longevity. We make the petrochemical solutions found in products of all kinds with purpose, collaboration and care. Its great to have the opportunity to talk about both. Our team of experts answer the most frequently asked questions. %PDF-1.6 % However, Group III base stocks are derived from multiple feedstock choices and processing technologies, which create variability in the properties. The chart below shows the operating temperature range of a PAO-based, OMG process grease versus comparable mineral-oil-based grease. PPDs act only on linear or waxy compounds, and these characteristics are absent from PAOs. 176 0 obj During 2011, Chevron Phillips Chemical acquired PAO assets in Beringen, Belgium, and began mPAO production in Texas. <]/Prev 170099>> The qualitative chart below describes the impact of each grease component on certain performance characteristics: Clearly, the base oil dominates some grease properties, while the additives or thickener drives others. Copyright 2023 Chevron Phillips Chemical Company LLC. 0000135019 00000 n 0000048689 00000 n These excellent pour points are achieved while increasing the viscosity indices (VI) over traditional HV PAO. The absence of these structures and materials results in a very non-polar base oil with a high viscosity index (of approximately 130), excellent low-temperature flow and pour-point characteristics, good oxidation stability and compatibility with mineral oils, paints and seals commonly found in lube oil systems. The relative availability of olefin monomer was certainly a consideration (i.e., 1-octene vs. 1-decene). NLGI #2. To get a superior lubricant, you need to start with a superior base oil. PAG- and PAO-based lubricants rarely compete in industrial applications. There are several systems where we have observed a reduction in the operating temperature compared to mineral oils, including transmissions, engines and heat transfer applications. These advantages show that PAOs address problems other fluids cannot. Conversely, if you reduce the temperature, the reaction rate decreases and the oil lasts longer, providing better protection. 0000017608 00000 n The chart differentiates the blending capabilities of various base oils to meet energy-efficient motor oils. Buna-N Satisfactory for "O . Low-viscosity PAO fluids are used in automotive applications, such as engine oil and gear lubricants. It is a synthetic hydrocarbon (SHC) that mimics the best hydrocarbon (branched, non-ring) structure found in mineral oils and so corrects for many disadvantages of using mineral oil lubricants, including poor low-temperature fluidity, poor viscosity index, sludge deposits, and high volatility. It is a synthetic hydrocarbon (SHC) that mimics the best hydrocarbon (branched) structure found in mineral oils. The VI trend is only true for a family of base oils. 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. Not a subscriber or a registered user yet? This is one clear benefit of using a carefully designed base oil. Were a company with deep-rooted values, and were looking for people like you to join our team. But wait, it gets even better! This formulation achieved a 13% benefit when the PAO was directly substituted with Synfluid PAO. proof:pdf In order of volume used, they are: polyalphaolefins (PAOs), organic esters, and polyglycols. 101 0 obj The challenge presented to a formulator is maintaining the performance levels while achieving biodegradability. Furthermore, the advantages of exceeding the minimum requirements for driveline fluids will enhance the benefits of the finished lubricant. H*T034R0 BC0k ` f- The first step is the synthesis of oligomers (polymers with few repeating monomer units) from the linear alpha-olefin. Additionally, PAOs have high viscosity indices, which lead to less film thickness reduction at elevated temperatures. We agree, deciphering the requirements that allow you to identify your products as eco-friendly such as the upcoming BioPreferred label can be mind-boggling! Ethylene is produced by cracking either crude oil or natural gas. 232 0 obj PAOs are the most common synthetic basestock used in industrial and automotive lubricants.

The difference in the CCS viscosity at -35C is 15 percent, which is substantial. Polyglycols-40 to 125 C Dominant in a commercial sense are polyethylene and polypropylene. One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. endobj PAG-based lubricants provide many property and performance advantages over mineral oil-based and other synthetic lubricants, as outlined in Table 2. After the formation of the Chevron Phillips Chemical joint venture in 2000, a 10 KTA PAO unit expansion followed soon thereafter. mary berry grandchildren names . 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. These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile. Unlike other industrial basestocks, PAOs are generally classified by their kinematic viscosity at 100C. For the highest quality and performance, choose Synfluid PAO. The choice of C10- or C12-derived PAO depends on the application and/or specification requirements. To improve seal compatibility of PAO-based lubricants, an ester is added to . default This lowers their volatility, creates less hydrocarbon tailpipe emissions and raises the flash point. Compatibility testing is generally carried out at high temperatures, simulating an accelerated life and poor or stressful conditions for the plastic and elastomer/rubber.
