Typically, petroleum-base oils are not synonymous with terms like green or environmentally friendly. Chemical Compatibility Guide Later used in many industrial applications from compressor, hydraulic, and turbine fluids to gear oils and metalworking fluids. 10.1 Introduction. This article will discuss the most common synthetic fluids aiming to help end-users make the right choice for their applications. Synfluid PAOs are crafted from an on-purpose process that yields a consistent, high-quality product. At that time, both fires on U.S. Navy ships and aircraft were occurring due to the use of mineral oil-based hydraulic fluids. This will increase the dependence on high-quality base oils such as PAOs. As the chart above clearly demonstrates, the difference in viscosity as a function of shear rate is magnified as temperature decreases. To mitigate this effect, We recommend taking a look at Synfluid PAO 5 and PAO 7, due to their excellent Noack volatilities of 5.5% and 2.3%, respectively. False Specific heat is the amount of heat per unit mass required to raise the temperature one degree Celsius. Why does this happen? For the highest quality and performance, choose Synfluid PAO. The first step is the synthesis of oligomers (polymers with few repeating monomer units) from the linear alpha-olefin. The viscosity at an extreme pressure (hp) changes exponentially with pressure (P) as described in the following formula: a is the pressure coefficient for a base oil. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 162 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> 0000055257 00000 n polyalphaolefin compatibility chart. It is possible to get added property benefits from C12-based Synfluid PAOs. Chevron Phillips Chemical offers two lines of PAOs. Grease is a solid to semi-fluid lubricant, typically used for difficult to service equipment, such as bearings or suspension systems. We make the petrochemical solutions found in products of all kinds with purpose, collaboration and care.

Temp. 165 0 obj PAO-based greases are typically used at temperatures over 100C because of thermal and oxidative concerns. Adobe InDesign CS6 (Macintosh) The PAOsare produced through synthesizing oligomers of either 1-decene or 1-dodecene. Approximately 80% of synthetic lubricants used in the world are of three types. The lower volatility decreases oil replacement costs by reducing oil consumption. As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. Volatility is a concern for many applications, especially where higher operating temperatures occur or longer service life is desired. PAO-base oils help improve fuel economy in engine and drivetrain oils by reducing viscosity, volatility and traction coefficients as the chart below shows: These results show the potential for reducing friction loss using PAOs, which also typically have lower pressure-viscosity coefficients than mineral oils reducing elastohydrodynamic gear friction losses and energy consumption. C12-derived PAOs also provide advantages with higher Viscosity Index (VI), better flash/fire points, and even lower cold crank simulated viscosities. mary berry grandchildren names .

Adding a PPD will reduce the pour point of a mineral oil, but it still will not achieve the performance of a PAO. The use of mineral oil-based lubricants in the world, however, is decreasing. The chart differentiates the blending capabilities of various base oils to meet energy-efficient motor oils. esters or alkylated naphthalenes) to improve their solvency and deposit control. As the viscosity grade decreases, the volatility and high-temperature/high-shear viscosity will be limiting factors. The degree of the disadvantage for seal and paint compatibility may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). PAOs also resist viscosity increases upon oxidation, which is important in sequence IIIE and VW T4 engine tests. Chemical Compatibility Guide 0000052609 00000 n Furthermore, the arbitrary distinction of 120 VI between Group II and III oils makes the quality requirements even more confusing. These include the tendency to shrink seals and trouble dissolving common oil additives. The chart below shows a comparison of the foaming characteristics of our Synfluid mPAO high-viscosity base oils with traditional high-viscosity PAO 40 and 100 cSt base oils. LDPE is defined by a density range of 0.910-0.940 g/cm3.
