With Synfluid PAO 4 cSt having a 73C ppt and 40C viscosity of 2,380 cSt, a PPD is not necessary. The superior low-temperature flow characteristics of PAOs ensure faster coating of critical parts in the compressor during startup, minimizing wear. When unsure of a components precise identity or version, the manufacturer After the formation of the Chevron Phillips Chemical joint venture in 2000, a 10 KTA PAO unit expansion followed soon thereafter. General properties of low- and high-viscosity conventional PAO, and metallocene-catalyzed mPAO basestocks, are shown in Table 4. <>stream

The results indicate that the CSC 980 Tan grease has a running torque of 3.77 N-m versus 10.9 N-m for the same grease with an alternate base oil. We believe it can be understood by looking at the thermal conductivity and specific heat of the base oils. More uniform in structure than conventional PAO basestocks, they provide similar advantages of high viscosity indices, excellent low-temperature fluidity, and shear stability but with additional thickening ability. Weve got you covered! These excellent pour points are achieved while increasing the viscosity indices (VI) over traditional HV PAO. <>stream
A formulator choosing the right base oil is like a craftsman choosing the right tool it needs to fit the job. False Aviation hydraulics require the use of PAOs because of the inherently high flash/fire points and low volatility. PAOs also resist viscosity increases upon oxidation, which is important in sequence IIIE and VW T4 engine tests. Chemical Compatibility Guide 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. 97 0 obj mary berry grandchildren names . Better heat transfer coefficients, increased lubricity and the basic chemical structure of PAOs all contribute to the lower temperature in the gearbox.

A similar approach can be applied to your formulations or applications. We believe that it is possible to achieve a passing mark with even lower amounts of PAO, further reducing costs. PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. However, not all synthetic lubricants are created equal. 0
Use of WGHFs increased tremendously due to the publication of the Luxembourg Report in 1961, outlining minimum standards for hydraulic fluid fire-resistance in European coal mines. The VI of PAOs typically only varies one to two points. 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.). <> 0000004968 00000 n
California Transparency in Supply Chains Act Disclosure. The C12-derived PAOs were created to give better volatility, giving formulators four new options when choosing PAOs. Focusing on the components of the additive package can further influence the performance of the formulation. Effect of Base Oil Type on Gear Box Temperatures. PAG lubricant basestocks can be designed to be water-soluble, water-insoluble (partial mineral oil compatibility), or oil-soluble, depending on the selection of starter molecules and monomers to be used in producing the polymer. Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. According to the U.S. government, biobased is defined as at least 44% biobased carbon content for hydraulic fluids.

Absolutely! PAOs on the other hand are derived from a clearly defined processing technology using petrochemically pure alpha olefins. <> 179 0 obj To help you optimize your application, Chevron Phillips Chemical offers a wide variety of PAOs delivering oxidative and thermal stability advantages. As temperature decreases, a higher VI fluid will have reduced viscous drag, which could lead to higher horsepower and energy efficiency. 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). However, unlike foaming, entrained air can be a difficult problem to treat with additives. Having a high viscosity index helps to protect an engine at temperature extremes. 0000001605 00000 n

In these extreme services, a PAO-based lubricant is able to reach the area that requires lubrication and prevent damage or wear. PAO- and PAG-based lubricants are both hydrolytically stable and have low pour points. 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. To improve seal compatibility of PAO-based lubricants, an ester is added to the formulation to add some polarity. 10.1 Introduction. However, moving to lower-viscosity oils is a possibility only if you can maintain a low Noack volatility for emissions control and lubricant stability. converted 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.

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. In terms of viscosity, there are tradeoffs in choosing one PAO over another: energy consumption (heat dissipation and production throughput) versus safety of operations (impacted by flash/fire points and volatility). Compatibility testing includes heating and holding grease for a specified time at assumed operating temperature for mixtures of 10:90, 50:50 and 90:10. 0000161810 00000 n
