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. Low molecular weight compounds will degrade other performance requirements, such as volatility, flash and fire points. Challenges like these truly reveal the performance advantages of Synfluid PAOs. Because of their controlled structure, PAOs do not contain lighter, more volatile (small) hydrocarbons. 0000033764 00000 n Remember, PAOs are carefully designed, not refined. As pressure increases, so too does the viscosity of the lubricant. The table below shows how our new Synfluid mPAOs offer significant advantages in pour point and viscosity index over conventional high-viscosity PAOs. Actions. D = Severe Effect, not recommended for ANY use. Chemical Compatibility Guide 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.). Defense Daily subscriber and registered users, please log in here to access the content. Two major types of synthetic basestockspolyalkylene glycols (PAG) and polyalphaolefin (PAO)and the lubricants formulated from them, will be compared. Thats a hot topic! Air is usually a really poor lubricant, so your frustration is understandable! Reducing the viscosity of engine and drivetrain oils lowers fuel consumption by decreased churning losses and viscous drag. One example is the advantage PAO has over mineral oil in the area of high-temperature stability. Polyalphaolefins also have poor fire resistance and biodegradability.

Consistent feedstocks give rise to consistent PAO quality, resulting in consistent finished fluid performance. PAO- and PAG-based lubricants are both hydrolytically stable and have low pour points. Our C10-based products, commercialized in the 1970s, were the first in the market. Chemical Compatibility Chart (cont.) However, PAOs can help. Because PAOs have a diverse, highly branched isoparaffin structure, they provide excellent low-temperature viscometrics and very low pour points (ppt) without adding PPDs. Later used in many industrial applications from compressor, hydraulic, and turbine fluids to gear oils and metalworking fluids. Although PAOs are not considered biobased themselves, in a blend they contribute certain performance benefits. However, VI doesnt tell the whole story it only reflects the viscosity/temperature relationship between 40C and 100C. The superior benefits of PAOs enable formulators to meet these challenges. As a result, the jump in the viscosity adversely effects the ability to pump at low temperatures. polyalphaolefin compatibility chart Posted by . False 0000012542 00000 n Whether its transportation or industrial lubes, greater fuel efficiency means lower operating costs. 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. In contrast, a mineral oil will require various antioxidants depending upon the structural makeup. what chemicals to use The chart below shows the operating temperature range of a PAO-based, OMG process grease versus comparable mineral-oil-based grease. A process enhancement at Chevron Phillips Chemicals manufacturing facility has resulted in up to a 30 percent improvement in oxidative stability when used with aminic antioxidants in Rotary Bomb Oxidation Tests (RBOT). Some claim the Viscosity Index (VI) is the overriding parameter used when choosing a base oil. 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. 0000027693 00000 n <<264FCCC095A7AD46A42A03D56AD5B96C>]>> Use this chart to help guide your component selection.

Base Oil Compatibility Chart Base Oil . Synfluid PAOs are already known for their excellent low-temperature and oxidative stability properties. Therefore, at high temperatures, it is advantageous to utilize a more stable base oil, specifically Synfluid PAO. When PAO 5 and PAO 7 are compared to equiviscous blends of other PAOs, the volatility advantage can be seen more clearly. This formulation achieved a 13% benefit when the PAO was directly substituted with Synfluid PAO. The C12-derived PAOs were created to give better volatility, giving formulators four new options when choosing PAOs. endobj Jun 09 Comentarios desactivados en polyalphaolefin compatibility chart. Conversely, if you reduce the temperature, the reaction rate decreases and the oil lasts longer, providing better protection. Dominant in a commercial sense are polyethylene and polypropylene. What is most interesting, however, is the low-temperature performance: The C10-based PAO 6 has the lowest pour point by over 20C, but the CCS viscosity for the C12-based PAO 5 and 7 blend is better. A relatively simple test, the criteria of the test varies depending on which grease manufacturer you are dealing with. Polypropylene Satisfactory to 72 F. C Moderate effectFair D Severe effectNot recommended FOOTNOTES 1. 1 . endobj 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. Finally, greater oxidative stability extends oil life and keeps the compressor clean for a longer service interval. 0000055257 00000 n 0 Kinematic Viscosity @ 100C (cSt) Kinematic Viscosity @ 40C (cSt) Pour Point (F) Molecular Weight. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 163 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> After all, the reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. This Chemical Compatibility Chart is a shorthand tool for describing the suitability of miniature fluidic and pneumatic component materials for use in contact with various chemicals. 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. Two lubricants with the same VI may perform dramatically differently at low temperatures. For example, the fraction that has predominantly the 1-decene trimer (C30 oligomer) has a 100C viscosity of 4 cSt and is known as PAO 4. As an example of the improved low-temperature torque properties of the PAO-based grease, the chart below shows torque values for Chemtools CSC 980 grease under ASTM D 4693 test conditions for rotation of a wheel-bearing assembly at -40C.
