False 91 0 obj The chart below shows an example of an engine oil formulation with two different quality PAOs. 4 6 With regard to performance, PAOs are able to maintain excellent thermal and oxidative stability at high operating temperatures in addition to the low-temperature benefits for which they are known. Unlike other industrial basestocks, PAOs are generally classified by their kinematic viscosity at 100C. They are usually derived from a small set of simple olefins ( alkenes ). %PDF-1.4 % 304 Stainless Steel Chemical Compatibility Chart ver 28-Oct-2022 Key to General Chemical Resistance - All data is based on ambient or room temperature conditions, about 64F (18C) to 73F (23C) A = Excellent C = Fair - Moderate Effect, not recommended The properties mentioned above are in addition to the normally excellent performance you have come to recognize with PAO. PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. 0000003107 00000 n Lowering torque reduces the energy requirements of the equipment and improves grease distribution. Synfluid PAOs have very narrow molecular weight ranges, which are attributed to our high-purity feedstocks. Galvanized steel is susceptible to attack by some chemicals which may cause . 0000161553 00000 n 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. So you can look to Synfluid PAO to help you formulate lubricants with both environmental benefits and outstanding performance properties. So yes, PAOs can provide flexibility in your food-grade base oil selection, depending upon your performance requirements. The chart below shows rotary bomb (ASTM D2272) results between Synfluid PAOs and some mineral oils. Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene. 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. Compatibility testing is generally carried out at high temperatures, simulating an accelerated life and poor or stressful conditions for the plastic and elastomer/rubber. 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. Since PAO fluids are synthetic hydrocarbons, they are compatible with and often combined with mineral-based oils. 0000013783 00000 n The direct feedstock (normal alpha olefin - NAO) is produced through the chain growth and displacement process for producing petrochemically pure alpha olefins. Polyalphaolefin Characteristics endobj Because PAOs have a diverse, highly branched isoparaffin structure, they provide excellent low-temperature viscometrics and very low pour points (ppt) without adding PPDs. 0000139641 00000 n General properties of low- and high-viscosity conventional PAO, and metallocene-catalyzed mPAO basestocks, are shown in Table 4.

Chemical Compatibility Chart (cont.) 0000139372 00000 n PAO-based lubricants offer a significant advantage in oxidative stability. Effect of Base Oil Type on Gear Box Temperatures. The chart below illustrates the relative effect base oils have on the operating temperatures in a modified four-ball machine. The reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. 0000000016 00000 n Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. 0000000016 00000 n NLGI #2. The VI of PAOs typically only varies one to two points. As the chart above shows, lower-viscosity oils can be made without sacrificing low volatility by using PAO base oils. However, these products have demonstrated unique advantages in Sequence IIIF, VW T4 and TDI tests due to many of the other properties that are inherent in them. 0000134768 00000 n Since there are no other discernable compounds, Synfluid PAOs are more readily biodegradable and can be used for some food applications. 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. Lower-viscosity PAOs have a unique property of biodegradability. General properties of water-soluble, water-insoluble, and oil-soluble PAG basestocks are shown in Table 1. To improve fuel economy, OEMs are moving toward lower-viscosity oils, even in heavy-duty diesel engines. When PAO 5 and PAO 7 are compared to equiviscous blends of other PAOs, the volatility advantage can be seen more clearly. Give us a call.

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. 2023 Access Intelligence, LLC - All Rights Reserved. <> 0000004968 00000 n The magnitude of these benefits will depend on the particular formulation. During 2011, Chevron Phillips Chemical acquired PAO assets in Beringen, Belgium, and began mPAO production in Texas. 0000034554 00000 n To correctly identify what type of fluid is needed, the end-user must know the minimum lubricant requirements for that piece of equipment. The information from such third party sources is believed to be reliable and accurate; however, Purchaser should make its own determination of compatibility before using any SpillTech product. Some claim the Viscosity Index (VI) is the overriding parameter used when choosing a base oil. 2023 DuPont. The chart below shows the trends in industry specifications regarding low-temperature performance relative to Synfluid PAO. Chevron Phillips Chemical has been producing two families of PAOs for close to 25 years. The superior low-temperature flow characteristics of PAOs ensure faster coating of critical parts in the compressor during startup, minimizing wear. The chart below shows biodegradation test results for Synfluid PAO 2.5, 4 and C12 Dimer, which indicate that these products could qualify as inherently biodegradable according to the ASTM D5864 test method. 0000001332 00000 n The combination of air and oil can often lead to foaming issues. 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. Our sustainability strategy encompasses the concerns and issues identified by our stakeholders and we are committed to addressing these issues. Address new equipment conditions (higher operating temperature and pressure, greater loads and speed). The chart below shows specific properties of four of our PAO grades that are well-suited to metalworking applications. 0000135019 00000 n It is a synthetic hydrocarbon (SHC) that mimics the best hydrocarbon (branched) structure found in mineral oils. This process creates a polymer backbone where oxygen is every third atom, which gives PAG basestocks their distinctive chemical attributes and allows formulators to synthesize various combinations of starters and monomers (block, random, and homopolymer) to create custom basestock types for specific applications. Oxidative stability is a critical property enabling oils to resist sludge formation and degradation while in service. This is compared to a conventional hydraulic fluid in the chart below. 0000032842 00000 n ]-]jW|^X^=E^7J3kgI%_9+v}Fwq{r9 *d(C>~z|7X#o!9lwu{^1se9),7v)mE,wa?t3 a$X{wzVAw}E^:5--_OXY+.
