Use our Chemical Compatibility Chart as guide for evaluating the resistance of polymer and metal materials to a wide range of chemicals found in industrial . This is a recurring situation and is what led to the development of 1-dodecene based Synfluid PAOs in 1995. As shown in the chart below, our PAOs have shown very little fluctuation over the years, with stable viscosities at 100, 40 and -40C even as weve made improvements to characteristics such as oxidative stability. endobj We look forward to helping you consolidate your grease cabinet! Some claim the Viscosity Index (VI) is the overriding parameter used when choosing a base oil. The VI of PAOs typically only varies one to two points. xmp.did:F87F1174072068118083E936383AAE83 This same technology can also be beneficial for biobased gear lubricants, chain and cable lubricants/greases, and other applications for equipment used in sensitive environmental areas. 0000000016 00000 n 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. It is not reactive at room temperatures, except by strong oxidizing agents, and some solvents cause swelling. Driveline specifications continue to become more stringent. 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. PAG basestocks are synthetic polymers manufactured using a polymerization process that combines monomers ethylene oxide (EO), propylene oxide (PO), and butylene oxide (BO) singly as homopolymers or in combinations to form a growing chain from a nucleophilic starter molecule, commonly an alcohol. converted 0000134768 00000 n However, nothing is perfect, and polyalphaolefin base oils do have a few negative characteristics. Low-viscosity PAO fluids are used in automotive applications, such as engine oil and gear lubricants. The superior low-temperature flow characteristics of PAOs ensure faster coating of critical parts in the compressor during startup, minimizing wear. xmp.iid:00801174072068118083E936383AAE83 . Synfluid PAOs have very narrow molecular weight ranges, which are attributed to our high-purity feedstocks. It is a synthetic hydrocarbon (SHC) that mimics the best hydrocarbon (branched) structure found in mineral oils. endobj Typically, petroleum-base oils are not synonymous with terms like green or environmentally friendly. 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. In order of volume used, they are: polyalphaolefins (PAOs), organic esters, and polyglycols. In contrast, the Synfluid PAO formulation achieves a pass with as little as 30 percent PAO, the balance being Group I mineral oil. The 2002 U.S. Farm Bill Act mandates government agencies to purchase environmentally safe, biobased (vegetable oil) lubricants. When possible, testing compatibility between the specific PAG lubricant to be used and the specific seal types or paints to be used is recommended. Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants. 273 0 obj <> endobj xref 273 24 0000000016 00000 n European specifications, as well as those in other regions, are expected to tighten. 0000001605 00000 n Sustained operations at elevated temperatures increase the rate of oxidation and other degradation reactions. Galvanized steel is susceptible to attack by some chemicals which may cause . Glad you asked! Ethylene is produced by cracking either crude oil or natural gas. trailer So yes, PAOs can provide flexibility in your food-grade base oil selection, depending upon your performance requirements. PAO-based lubricants have good viscosity indices superior to lubricants based on Group I, II, and III basestocks of similar viscosity (without the addition of a viscosity improver). The degree of the advantage may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). The PAOsare produced through synthesizing oligomers of either 1-decene or 1-dodecene. Some of the disadvantages of PAO-based lubricants are outlined in Table 6. xmp.id:B2FC01B10F2068118083E936383AAE83 Chemical Compatibility Guide 0000022832 00000 n Understanding the advantages and disadvantages of each can help end-users decide which option is best for a given application. PAOs offer exceptionally low volatility due to their controlled formation, which yields carefully designed molecular weights. As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. startxref The reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. However, not all synthetic lubricants are created equal. False While pour point is one consideration, a formulator has to take into account the total specification needs. The chart below shows the effect of two different shear rate viscosity determinations on three different fluids (4 cSt at 100C) and the dramatic differences between them. During 2011, Chevron Phillips Chemical acquired PAO assets in Beringen, Belgium, and began mPAO production in Texas. Additionally, PAOs have high viscosity indices, which lead to less film thickness reduction at elevated temperatures. 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. The VI trend is only true for a family of base oils. While viscosity improvers can enhance VI, they can break down over time, resulting in diminished performance. In contrast, a mineral oil will require various antioxidants depending upon the structural makeup. hb```f``g mBU L4#o0 D %PDF-1.4 % According to analysis conducted by Kline & Co., more than 78% of all lubricant requirements in the world annually are met with the use of mineral oil-based fluids. 0 Grade Name. 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. Address specific system site conditions (potential for water ingression). The C12-derived PAOs were created to give better volatility, giving formulators four new options when choosing PAOs. With the powerful combination of MOLYKOTE Specialty Lubricants and DuPont Polymers, our understanding of grease-polymer compatibility allows our customers the unique ability to select products faster and move through validations with confidence. Specific tests such as the Volkswagen T-4, TDI and Peugeot TU-5 have increased the demand for higher-quality base oils. This is especially true when you consider the entire operating temperature range including startup. The primary difference between these two products is pour point. A relatively simple test, the criteria of the test varies depending on which grease manufacturer you are dealing with. Of course, and your options are growing! The properties mentioned above are in addition to the normally excellent performance you have come to recognize with PAO. A similar approach can be applied to your formulations or applications. Since we use essentially pure 1-decene or 1-dodecene to produce Synfluid PAOs, there is a narrow isomeric distribution for each oligomer. In drivetrain lubricants, reducing the traction coefficient and lowering viscosity are key ways to increase fuel economy, but lower viscosity must be balanced to provide adequate wear resistance. Our unique PAO 2.5cSt further improves flash/fire points by as much as 10 percent over other commercial polyalphaolefins. 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. Low-temperature fluidity and high-temperature thermal and oxidative stability are key factors for choosing a PAO. 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. Typically, as the viscosity drops, the volatility increases. The chart differentiates the blending capabilities of various base oils to meet energy-efficient motor oils.
