Business never stands still, but you can always count on dependable Chevron Phillips Chemical Synfluid PAOs. application/pdf These synthetic hydrocarbons are designed to provide superior lubrication performance over a wider operating-temperature range than petroleum oils and typically are less volatile. The magnitude of these benefits will depend on the particular formulation. 1 . Polyalphaolefins offer great high temperature properties and low volatility. For example, one would not be able to make an 0W-20 oil with a C12-derived PAO as the viscosities are too high. When PAO 5 and PAO 7 are compared to equiviscous blends of other PAOs, the volatility advantage can be seen more clearly. endobj Having a high viscosity index helps to protect an engine at temperature extremes. 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. 0000036029 00000 n For white oil applications, this high saturation level would give a greater degree of chemical inertness. Because a certain level of biodegradability can be achieved without sacrificing PAOs key benefits, a finished lubricant based on a PAO/biobased blend will maintain superior properties over an extended period of time, resulting in less waste. endobj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 159 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> With many new base oils being introduced to the market, lubricant consistency can really be a challenge.

Specific tests such as the Volkswagen T-4, TDI and Peugeot TU-5 have increased the demand for higher-quality base oils. Polypropylene Satisfactory to 72 F. C Moderate effectFair D Severe effectNot recommended FOOTNOTES 1. As a result, the jump in the viscosity adversely effects the ability to pump at low temperatures. For instance, a 100 percent aminic antioxidant package will yield the best performance in the Rbot test for PAO. PAOs also resist viscosity increases upon oxidation, which is important in sequence IIIE and VW T4 engine tests. All rights reserved. However, moving to lower-viscosity oils is a possibility only if you can maintain a low Noack volatility for emissions control and lubricant stability. Driveline specifications continue to become more stringent. Synfluid mPAOs exhibit faster air release times, particularly when comparing the 100 cSt blends. Because PAOs have a diverse, highly branched isoparaffin structure, they provide excellent low-temperature viscometrics and very low pour points (ppt) without adding PPDs. PAO-based lubricants generally resist creep and water washout and offer good lubricity across a variety of substrate material pairings, including metal-to-metal and metal-to-plastic. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 160 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> Regarding the A.O. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 161 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> from application/x-indesign to application/pdf H*T034R0 BC0k ` f- PAOs are Newtonian fluids; in other words, their viscosities are fairly independent of shear rate. The chart below illustrates how Chevron Phillips Chemical has come up with an economical solution to a VW T-4 engine test. Their polymerization can benefit greatly from the development of highly active and highly selective catalysts, as the catalysts strongly affect their properties. In addition, low viscosity SpectraSyn PAO products are hydrolytically stable, have good compatibility with mineral oils and are frequently combined with other synthetic basestocks (e . These requirements or specifications will generally identify or recommend a product type (mineral oils, synthetic fluids, or bio-based fluids) and the proper performance requirements (developed into the lubricant by the component chemistry) to allow the machinery to run at an optimum level. The chart above shows the exceptional pour points of Synfluid mPAO 65, 100 and 150 cSt compared to traditional PAO 40 and 100 cSt. 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). Jun 09, 2022. polyalphaolefin compatibility chart . 0000021835 00000 n Synfluid PAOs are designed to provide stable viscosities at low temperature and excellent viscometrics and deliver oxidative stability. Synthetic lubricants can be very different chemically and what defines those differences are the basestocks used as the basis for the lubricant. This resistance to fire and flame propagation improves the margin of safety in the event of a hydraulic leak. general guideline for pump material selection There are multiple considerations when determining the best synthetic lubricant for a particular application, but knowledge of the general properties of the synthetic lubricant types being considered is the starting point. Some of the disadvantages of PAO-based lubricants are outlined in Table 6. After the formation of the Chevron Phillips Chemical joint venture in 2000, a 10 KTA PAO unit expansion followed soon thereafter. Synfluid PAO 5 and PAO 7 also offer several advantages in addition to the volatility, such as low pour point, high viscosity index, improved oxidative stability and excellent low-temperature viscosities. Although PAOs are not considered biobased themselves, in a blend they contribute certain performance benefits. PAG polymers, first discovered more than 150 years ago, saw their breakthrough application occur during World War ll. D = Severe Effect, not recommended for ANY use. Understanding this advantage is important for optimizing the performance of todays fluids and improving the life of equipment. For instance, excellent water separation improves compressor operability by reducing the chance of emulsion formation. Sometimes, one plus one can equal more than two.

This will increase the dependence on high-quality base oils such as PAOs. The vast number of high-quality base oil choices can be daunting when trying to balance fuel efficiency and wear protection. These units provide a flow of temperature controlled fluid or Polyalphaolefin liquid. 180 0 obj So, whether used for gear or engine oils, PAOs provide more consistent properties and a level of purity not available from other base oil groups. Volatility is a concern for many applications, especially where higher operating temperatures occur or longer service life is desired. Since PAO fluids are synthetic hydrocarbons, they are compatible with and often combined with mineral-based oils. hence, compatibility with base-oil molecules like PAO oil is improved. For instance, boosting the additive package with an additional 0.4% aminic antioxidant, in combination with the Synfluid PAO base oil, achieved a 35 percent improvement in HPDSC results. The more EO monomer in the basestock, the more water-soluble; the more PO monomer, the more water-insoluble; and the more BO monomer, the more oil-soluble the basestock is. PAO- and PAG-based lubricants are both hydrolytically stable and have low pour points. xmp.id:B2FC01B10F2068118083E936383AAE83 They may also be used in applications and areas that may result in incidental food contact or on equipment where there is a potential exposure of the lubricated part to food, such as on food processing equipment as a protective anti-rust film.
