Synthetic lubricants can meet these demands because they perform better than mineral oil-based lubricants in many or all the critical performance areas: reduced wear and friction, resistance to sludge formation, lower volatility, greater corrosion protection, and improved thermal and oxidative stability. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 163 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> In these extreme services, a PAO-based lubricant is able to reach the area that requires lubrication and prevent damage or wear. There are emerging markets that demand the improved VI and volatility that only the C12-based PAOs can deliver. 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 . Polyalphaolefin Characteristics The first step is the synthesis of oligomers (polymers with few repeating monomer units) from the linear alpha-olefin. We make the petrochemical solutions found in products of all kinds with purpose, collaboration and care. cally stable, have good compatibility with mineral oils and can be combined with other more polar synthetic basestocks (e.g. hence, compatibility with base-oil molecules like PAO oil is improved. This process creates a polymer backbone where oxygen is every third atom, which gives PAG basestocks their distinctive chemical attributes and allows formulators to synthesize various combinations of starters and monomers (block, random, and homopolymer) to create custom basestock types for specific applications. Its estimated that over 100 million gallons of fluids leak from hydraulic machinery and other lubricant equipment in North America each year! They have different characteristics, meaning that one may be superior to the other under certain circumstances. This will increase the dependence on high-quality base oils such as PAOs. Satisfactory to 120F (48C) Ratings: Chemical Effect A = Excellent. Since this can be achieved without sacrificing hydrolytic stability, the finished lubricant will maintain superior properties over an extended period of time, resulting in less waste. 3 !1AQa"q2B#$Rb34rC%Scs5&DTdEt6UeuF'Vfv7GWgw ; !1AQaq"2B#R3$brCScs4%&5DTdEU6teuFVfv'7GWgw ? and PAO plays an integral part of meeting the challenge for top-tier oils. 0000034289 00000 n Group IIIB was unable to consistently pass the TDI or M111 tests. Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. You see, the jump hurts the pump.. Chevron Phillips Chemicals Synfluid mPAO 65, 100 and 150 cSt products have very high viscosity indices and lower pour points than other HV PAO products. 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.). We make the petrochemical solutions found in products of all kinds with purpose, collaboration and care. endobj application/pdf These products are acceptable for use as a lubricant (H1) or as a lubricant component (HX-1), with incidental food contact in and around food processing areas. Blending lower-quality base oils into this formulation would compromise the passing mark. Typically, petroleum-base oils are not synonymous with terms like green or environmentally friendly. You can see a medical doctor for your burn, but Dr. Ken Hope can help with your base oil and formulation challenges. Synfluid PAOs provide outstanding improvements in oxidation stability, volatility, water separability and viscometrics, greatly improving oil and hardware longevity. Polyolefins, including poly (ethylene), poly (-olefin), poly (styrene), and poly (dienes), are the most widely-used polymer materials. One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. Sorry, we couldn't find anything that matched your search, 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. Synthetic lubricants can be very different chemically and what defines those differences are the basestocks used as the basis for the lubricant. Thermal conductivity is the measure of the ability to conduct heat. <> They're found in everyday food and available as supplements. Polyalphaolefin does not contain ring structures, double bonds, sulphur, nitrogen components or waxy hydrocarbons. General properties of low- and high-viscosity conventional PAO, and metallocene-catalyzed mPAO basestocks, are shown in Table 4. The term synthetic hydrocarbon (SHC) is a general term. Because of this extensive chemical compatibility, which spans considerable concentration and temperature ranges, . Not Available - Chemical compatibility information is not available at this time. The benefit of a lubricant to the end user is an important question, and the behavior of a base oil is only one of many variables affecting the performance of a finished formulation. For other applications, PAOs safe and non-toxic nature allows it to be used where incidental food contact certification or kosher approval is necessary. 89 0 obj guide for chemical uses PAOs on the other hand are derived from a clearly defined processing technology using petrochemically pure alpha olefins. The difference in the CCS viscosity at -35C is 15 percent, which is substantial. xmp.did:00801174072068118083E936383AAE83 First, dont touch the gear box; you will burn your hand. This is one clear benefit of using a carefully designed base oil. So you can look to Synfluid PAO to help you formulate lubricants with both environmental benefits and outstanding performance properties. 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. This difference in polarity impacts many lubricant properties including elastomer compatibility, paint solvency, deposit control, and lubrication. Weve got you covered! 3.0 CHEMICAL COMPATIBILITY GUIDE FOR METALLIC MATERIALS In addition to this chemical compatibility chart, report TR-60C, Bal Seal has two other reports: report TR-60A "Chemical Compatibility Guide for Bal Seal PTFE, Filled PTFE, and Polyethylene Seal 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. Fluids are typically subjected to various shear and temperature conditions. %%EOF The higher the coefficient, the greater the change in viscosity at elevated pressures. endobj 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. Leaking fluids from equipment used in sensitive geographical areas can have long-term negative consequences on the environment. The differences in flash, fire, volatility and viscosity highlight the flexibility benefits of using a Synfluid PAO. Synfluid PAOs have helped you to meet industry specifications in the past. This new system improves the viscosity properties, which should be more energy conserving and achieves the ultimate biodegradation rating ASTM D5864-PW1. PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. 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. Chevron Phillips Chemicals proprietary manufacturing process and monomer selection combine to produce the groundbreaking performance characteristics that our customers expect from Synfluid polyalphaolefins. 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 Ethylene price in the Europe region was dull throughout the third quarter of 2022, which abetted the declining price trend of PAO throughout Q3 in Europe. The effects of the shear rate differences are even more exaggerated at low-temperature startup conditions, when the lubricant function is critical for equipment protection. Polyalphaolefins (PAO)-60 to 125 C Stable, lubricious fluids compatible with most plastics and elastomers. <> We offer a wide range of solutions essential to your products. If you would like us to test your formulation or have questions about our formulating experience, give us a call. Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene. The most favorable performance is achieved by using the highest-quality base oils. Oils made with PAOs demonstrate an inherently high viscosity index and maintain excellent low-temperature performance, compared with mineral oils. 0000036029 00000 n 0000161810 00000 n Working in conjunction with the Union Carbide Chemicals, Plastics Company Inc., and the Mellon Institute of Industrial Research, the USNRL developed the first water-glycol, PAG-thickened, fire-resistant hydraulic fluid (WGHF). 177 0 obj Polyphenols are a complicated group of plant-based chemicals. Having a high viscosity index helps to protect an engine at temperature extremes. 178 0 obj Sustained operations at elevated temperatures increase the rate of oxidation and other degradation reactions. 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. With regard to performance, PAOs are able to maintain excellent thermal and oxidative stability as well as the low-temperature benefits they are known for. Polyalphaolefins offer great high temperature properties and low volatility. Two major types of synthetic basestockspolyalkylene glycols (PAG) and polyalphaolefin (PAO)and the lubricants formulated from them, will be compared.
