High molecular weight compounds will degrade pour point, cold crank and other low-temperature viscometrics. Chemical Compatibility Guide The vast number of high-quality base oil choices can be daunting when trying to balance fuel efficiency and wear protection. This is a recurring situation and is what led to the development of 1-dodecene based Synfluid PAOs in 1995. More specialized polyolefins include polyisobutylene and polymethylpentene. For the highest quality and performance, choose Synfluid PAO. 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. Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants. PAO, Polyalphaolefin Liquid Chillers (PAO) from Bemco Inc. One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. 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 . Chemical Compatibility Guide - Galvanized Steel - SpillContainment.com Were a company with deep-rooted values, and were looking for people like you to join our team. PAG- and PAO-based lubricants rarely compete in industrial applications. 2023 Access Intelligence, LLC - All Rights Reserved. While pour point is one consideration, a formulator has to take into account the total specification needs. 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. hence, compatibility with base-oil molecules like PAO oil is improved. Remember, PAOs are carefully designed, not refined. Compatible with seals and paint used with mineral oil, no need for change at all operating temperatures. 0000017608 00000 n

Jun 09, 2022. polyalphaolefin compatibility chart . Great question! Lowering torque reduces the energy requirements of the equipment and improves grease distribution. Some specifications have a low-temperature MRV requirement. The qualitative chart below describes the impact of each grease component on certain performance characteristics: Clearly, the base oil dominates some grease properties, while the additives or thickener drives others. A drop-in replacement for petroleum, it's used in countless applications in many industries. Typically, as the viscosity drops, the volatility increases. Low-temperature fluidity and high-temperature thermal and oxidative stability are key factors for choosing a PAO. So yes, PAOs can provide flexibility in your food-grade base oil selection, depending upon your performance requirements.

Synfluid PAOs are designed to provide stable viscosities at low temperature and excellent viscometrics and deliver oxidative stability. Since then, the company has expanded PAO as well as ethylene production, both basic building blocks for many petrochemical processes. One way to achieve a higher VI base fluid is to shift from a decene-based PAO to a dodecene-based PAO. In contrast, the Synfluid PAO formulation achieves a pass with as little as 30 percent PAO, the balance being Group I mineral oil. 0000012542 00000 n
Challenges like these truly reveal the performance advantages of Synfluid PAOs. Furthermore, thermal conductivity at 300F for PAO 6 is 0.085 compared to 0.071 Btuft/(hft2F) for an equiviscous mineral oil, which means that the PAO can conduct 20percent more heat than the mineral oil for better heat dissipation. To correctly identify what type of fluid is needed, the end-user must know the minimum lubricant requirements for that piece of equipment. Synthetic lubricants can be very different chemically and what defines those differences are the basestocks used as the basis for the lubricant. 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. 1 - High Resistance 2 - Limited Resistance 3 - No Resistance . 142 0 obj

Sometimes, one plus one can equal more than two. The lighter components cause poorer volatility properties as well as lower flash and fire points. Glad you asked! Our Synfluid mPAO is based on a single monomer, AlphaPlus 1-Octene. Low-viscosity Synfluid PAOs are both NSF H1 and HX-1 registered. We expect that specifications for driveline fluids will continue to tighten due to pressure from energy conservation, improved transmission design and fluid longevity. But wait, it gets even better! 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. European specifications, as well as those in other regions, are expected to tighten. Some claim the Viscosity Index (VI) is the overriding parameter used when choosing a base oil. If pour point is not a critical property in your application, then blending a PAO 5 and PAO 7 might give you that clear advantage that you are looking for. Additives will increase the overall viscosities; however, PAO base oil leaves plenty of room for meeting specifications.
PAG basestocks are synthetic polymers manufactured using a polymerization process that combines monomers ethylene oxide (EO), propylene oxide (PO), and butylene oxide (BO) singly as homopolymers or in combinations to form a growing chain from a nucleophilic starter molecule, commonly an alcohol. Because of this extensive chemical compatibility, which spans considerable concentration and temperature ranges, . The challenge presented to a formulator is maintaining the performance levels while achieving biodegradability. Conversely, if you reduce the temperature, the reaction rate decreases and the oil lasts longer, providing better protection.

Having a high viscosity index helps to protect an engine at temperature extremes. If a polyurea-based thickener is chosen in conjunction with a synthetic base oil, such as a polyalphaolefin (PAO), there is no compatibility risk to be expected. 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 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. Satisfactory to 72 F. 3. Both lubricant types are used in industrial gearboxes, compressors, and even air conditioning systems. The magnitude of these benefits will depend on the particular formulation. endobj Sustained operations at elevated temperatures increase the rate of oxidation and other degradation reactions. 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). We believe that it is possible to achieve a passing mark with even lower amounts of PAO, further reducing costs. The chart below shows the operating temperature range of a PAO-based, OMG process grease versus comparable mineral-oil-based grease. We are first in your inbox with the most important news in the industry―keeping you smarter and one-step ahead in this ever-changing and competitive market.

Both the foam tendency (the initial amount of foam generated in this test) and the time required for the foam to collapse are remarkably better for Synfluid mPAO. 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.). 0
Typically, petroleum-base oils are not synonymous with terms like green or environmentally friendly. This new system improves the viscosity properties, which should be more energy conserving and achieves the ultimate biodegradation rating ASTM D5864-PW1. For instance, Chemtool Incorporated utilizes Synfluid PAOs in greases, and they have been able to formulate their products to take specific advantage of Synfluid PAO properties, yielding improvements in low-temperature mobility and torque. The chart below shows the trends in industry specifications regarding low-temperature performance relative to Synfluid PAO. A polyolefin is a type of polymer with the general formula (CH 2 CHR) n where R is an alkyl group. <> In both cases, the reduction in volatility will translate to lower oil consumption and reduced engine varnish over the life of the oil.
