As the chart above clearly demonstrates, the difference in viscosity as a function of shear rate is magnified as temperature decreases. After all, the reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. Driveline specifications continue to become more stringent. 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. A formulator choosing the right base oil is like a craftsman choosing the right tool it needs to fit the job. Using the same PAO, we achieved 15 percent higher oxidative stability by increasing the A.O. These include PAOs and also relatively common polyisobutenes (PIB), which are sometimes used as oil additives or as base oils in two-stroke engines. These oligomers are distilled and hydrogenated to yield specific molecular weight ranges that meet the viscosity grades that are desired. With Synfluid PAO 4 cSt having a 73C ppt and 40C viscosity of 2,380 cSt, a PPD is not necessary. High-viscosity PAO fluids have also become popular in industrial fluids and greases. 176 0 obj These products are acceptable for use as a lubricant (H1) or as a lubricant component (HX-1), with incidental food contact in and around food processing areas. This chart illustrates another benefit of using Synfluid PAOs at increased antioxidant treat rates. Some claim the Viscosity Index (VI) is the overriding parameter used when choosing a base oil. <> Our C12-based grades further improve flash/fire points by as much as 10 percent over other commercial polyalphaolefins. Benefits of the new system are a much higher viscosity index (VI), superior pour points and improved low-temperature fluidity, all of which contribute to improved energy efficiency. In addition to meeting current limits, a lower viscosity will reduce energy consumption. June 16, 2022; Posted by usa volleyball national qualifiers 2022; 16 . 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. endstream material chemical compatibility 0000014966 00000 n Synfluid PAOs have been carefully designed to yield oxidative induction times greater than 2,500 minutes with 0.5 percent antioxidant. This formulation achieved a 13% benefit when the PAO was directly substituted with Synfluid PAO. Specifically, soybean-derived oils or other bio-derived oils alone would not meet some oxidative stability and low-temperature performance requirements. To improve seal compatibility of PAO-based lubricants, an ester is added to . The chart below shows the operating temperature range of a PAO-based, OMG process grease versus comparable mineral-oil-based grease. As the chart above shows, lower-viscosity oils can be made without sacrificing low volatility by using PAO base oils. 1 . A relatively simple test, the criteria of the test varies depending on which grease manufacturer you are dealing with. Synfluid PAOs, in addition to NSF H1 qualification, are also available as kosher approved products. esters or alkylated naphthalenes) to improve their solvency and deposit control. Because metalworking processes can generate heat, these properties give you an intrinsic safety margin over the more volatile oils that are typically used. Use of PAG-based fluids and lubricants began to extend to other applications, first to quenchants and textile lubricants, then to many other lubricant categories, including anhydrous fire-resistant fluids, gear, compressor, and turbine fluids. 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. endobj While one lot of Group IIIA mineral oil passed this battery of tests, it is quite different from the quality of the other Group III stocks. Group V oils also include esters and naphthenic oils. It is really the formulators preference whether to increase the longevity of a vehicles moving parts, haul a heavier load, or save money at the fuel pump.
