Reasons to change from mineral oil-based lubricants to synthetics despite the increase in cost include: Advances in equipment technology have resulted in more demanding lubricant conditions and requirements, many beyond the capabilities of mineral oil-based lubricants. But wait, it gets even better! The most favorable performance is achieved by using the highest-quality base oils. When you add up the benefits, you may see that one plus one can make more than two. Since PAO fluids are synthetic hydrocarbons, they are compatible with and often combined with mineral-based oils. For example, one would not be able to make an 0W-20 oil with a C12-derived PAO as the viscosities are too high. However, moving to lower-viscosity oils is a possibility only if you can maintain a low Noack volatility for emissions control and lubricant stability. The chart below shows the gas chromatogram of PAO versus white mineral oil, illustrating the relative enhanced purity of PAO. Chemical Compatibility Chart (cont.) Engine oil tests such as VW T-4 and Seq. 0000018828 00000 n No matter what the combination of additive or base oil, one thing is certain: When you begin with a higher-quality base oil, you will achieve a better formulation in the end. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. 184 0 obj endstream endobj 12 0 obj<>/Metadata 9 0 R/AcroForm 13 0 R/Pages 7 0 R/Type/Catalog>> endobj 13 0 obj<>/Encoding<>>>>> endobj 14 0 obj<>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC]/Properties<>>>/ExtGState<>>>/Type/Page>> endobj 15 0 obj[/ICCBased 38 0 R] endobj 16 0 obj<>stream The magnitude of these benefits will depend on the particular formulation.

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. PAG basestocks are classified as a Group V oil, meaning a synthetic basestock that is not defined as a Group I, II, III, or IV base oil. It is not reactive at room temperatures, except by strong oxidizing agents, and some solvents cause swelling. Using the same PAO, we achieved 15 percent higher oxidative stability by increasing the A.O. 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.

Polyalphaolefins also have poor fire resistance and biodegradability. Naval Research Laboratory (USNRL) was begun to develop hydraulic fluids that would be more fire-resistant than the ones used at the time based on mineral oil. polyalphaolefin compatibility chart. There are emerging markets that demand the improved VI and volatility that only the C12-based PAOs can deliver. The rotary bomb bench test is a strong predictor of how base oils will perform in many automotive and industrial applications. PAOs are considered a very pure substance since they are derived from petrochemically pure ethylene and then from 1-decene or 1-dodecene, which could be considered a further purification step. PAO quality is unrivaled in the industry. 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.

Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene. Since we are all concerned with the protection of our environment, it is important to note some PAOs can be formulated with other components into biodegradable fluids. There are other advantages, such as oxidative and thermal stability, which you would naturally expect from a PAO-based product. Great question! MOLYKOTE. %%EOF Copyright 2023 Chevron Phillips Chemical Company LLC. 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). The absence of these structures and materials results in a very non-polar base oil with a high viscosity index (of approximately 130), excellent low-temperature flow and pour-point characteristics, good oxidation stability and compatibility with mineral oils, paints and seals commonly found in lube oil systems. 0000004079 00000 n 0000000724 00000 n PAG polymers, first discovered more than 150 years ago, saw their breakthrough application occur during World War ll. The plot below shows a comparison of the air release times exhibited by ISO VG 320 blends composed of our Synfluid mPAOs, and traditional HV PAOs with PAO 8 cSt. PAOs on the other hand are derived from a clearly defined processing technology using petrochemically pure alpha olefins. Challenges like these truly reveal the performance advantages of Synfluid PAOs. 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.

Several synthetic base oil types fall into the SHC category. 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. 177 0 obj The trend falls short when comparisons are made between PAOs and mineral oils, based solely on the VI. Synthetic lubricants can be very different chemically and what defines those differences are the basestocks used as the basis for the lubricant. All rights reserved. 0000036809 00000 n These include PAOs and also relatively common polyisobutenes (PIB), which are sometimes used as oil additives or as base oils in two-stroke engines. While pour point is one consideration, a formulator has to take into account the total specification needs. 0000012542 00000 n The dodecene-based products offer lower volatility at comparable viscosities to the decene-based products. 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. PAOs are Newtonian fluids; in other words, their viscosities are fairly independent of shear rate. Initially, it was intended to fill the gap in supply and was found to be exceptionally suitable for applications where extremely low pour points were not necessary. 9 0 obj <>stream 0000135615 00000 n When unsure of a components precise identity or version, the manufacturer 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.
