Process Chemical Compatibility Guide 0000162572 00000 n Whichever low-viscosity base oil is used, it must exhibit viscosity stability and low volatility. Meet new original equipment manufacturer and industry standard requirements. PAOs are Newtonian fluids; in other words, their viscosities are fairly independent of shear rate. PAO basestocks were developed in the 1930s and used commercially as a base for engine oils starting in the 1970s. Because of their controlled structure, PAOs do not contain lighter, more volatile (small) hydrocarbons. Sometimes, one plus one can equal more than two. While pour point is one consideration, a formulator has to take into account the total specification needs. 0000014966 00000 n The viscosity of the base oil is largely irrelevant in relation to the compatibility risks with the thickener. With Synfluid PAO 4 cSt having a 73C ppt and 40C viscosity of 2,380 cSt, a PPD is not necessary. Three stringent test standards required by Volkswagen and Mercedes-Benz engines show the impact of the variability of Group III oils: This data illustrates lot-to-lot variability, which has been recognized for the Group III oils. These excellent pour points are achieved while increasing the viscosity indices (VI) over traditional HV PAO. However, Synfluid PAOs can be formulated to be biodegradable and are well known for standing out from conventional base oils. 0000002226 00000 n After the formation of the Chevron Phillips Chemical joint venture in 2000, a 10 KTA PAO unit expansion followed soon thereafter. Compatibility testing includes heating and holding grease for a specified time at assumed operating temperature for mixtures of 10:90, 50:50 and 90:10. The information listed in parentheses is D-1418 nomencalture, common acronyms or common trade names. Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene. It is possible to get added property benefits from C12-based Synfluid PAOs. Adding a PPD will reduce the pour point of a mineral oil, but it still will not achieve the performance of a PAO. This clearly shows that a PAO base oil substitution can significantly lower operating temperatures of the gear box and extend the required maintenance interval. PAO SYNTHETIC MATERIAL COMPATIBILITY CHART This table is aids in the selection of elastomers, plastics and paints for use in conjunction with PAO synthetic fluids. 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.

You can see a medical doctor for your burn, but Dr. Ken Hope can help with your base oil and formulation challenges. These properties translate into easier distribution of the grease and improved energy efficiency in the equipment. %PDF-1.4 % However, VI doesnt tell the whole story it only reflects the viscosity/temperature relationship between 40C and 100C. PAOs demonstrate advantages in three key areas: safety, performance and environmental sensitivity. To correctly identify what type of fluid is needed, the end-user must know the minimum lubricant requirements for that piece of equipment. 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). 0000036915 00000 n Synfluid PAOs are already known for their excellent low-temperature and oxidative stability properties. . As the chart above shows, lower-viscosity oils can be made without sacrificing low volatility by using PAO base oils. The limits on lowering the viscosity grade are tied to the base oil properties. The lower volatility of Synfluid PAOs 5, 7 and 9 enhances the benefits for the highest quality lubricant. Changes in low-temperature viscometrics and oxidative stability requirements demand higher-quality base oils. 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. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. This is the case for blending Synfluid PAO 5 and PAO 7. The 2002 U.S. Farm Bill Act mandates government agencies to purchase environmentally safe, biobased (vegetable oil) lubricants. These oligomers are distilled and hydrogenated to yield specific molecular weight ranges that meet the viscosity grades that are desired. However, unlike foaming, entrained air can be a difficult problem to treat with additives. Polyalphaolefins offer great high temperature properties and low volatility. Polyphenols are a complicated group of plant-based chemicals. <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Thumb 164 0 R/TrimBox[0.0 0.0 792.0 612.0]/Type/Page>> 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.). It is a synthetic hydrocarbon (SHC) that mimics the best hydrocarbon (branched, non-ring) structure found in mineral oils and so corrects for many disadvantages of using mineral oil lubricants, including poor low-temperature fluidity, poor viscosity index, sludge deposits, and high volatility. 0000013783 00000 n Chemical Compatibility Guide; what chemicals to use; guide for chemical uses; general guideline for pump material selection; material chemical compatibility The mineral oil has both lighter and heavier molecular weight materials.

From then on, the company introduced 1-dodecene-based PAOs in 1995, which have grown steadily in popularity. The properties mentioned above are in addition to the normally excellent performance you have come to recognize with PAO. The relative availability of olefin monomer was certainly a consideration (i.e., 1-octene vs. 1-decene). However, these products have demonstrated unique advantages in Sequence IIIF, VW T4 and TDI tests due to many of the other properties that are inherent in them. Specific tests such as the Volkswagen T-4, TDI and Peugeot TU-5 have increased the demand for higher-quality base oils. Chemical kinetics tell us that if you reduce the temperature, you will reduce the reaction rate. Synfluid PAOs have helped you to meet industry specifications in the past. Since they are fully synthetic, Synfluid PAOs are extremely pure and provide inherent benefits in oxidative stability and viscosity performance at temperature extremes. However, nothing is perfect, and polyalphaolefin base oils do have a few negative characteristics. Adobe PDF Library 10.0.1 2013-07-10T14:05:23-05:00 Address specific system site conditions (potential for water ingression). There are many advantages! Additives will increase the overall viscosities; however, PAO base oil leaves plenty of room for meeting specifications. 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. The ability of a lubricant to reach critical metal-to-metal interfaces in a gear system can be the difference between operation or shutdown. what chemicals to use Great question! 0 As the viscosity grade decreases, the volatility and high-temperature/high-shear viscosity will be limiting factors. 0000000724 00000 n H|% `\ml emt8uHJs;7W*"_?~o~O? Were a company with deep-rooted values, and were looking for people like you to join our team. Chemical Compatibility Guide The VI of PAOs typically only varies one to two points. The term synthetic hydrocarbon (SHC) is a general term. When you add up the benefits, you may see that one plus one can make more than two. The degree of the advantage may depend on the specific PAG basestock type used (such as water-soluble, oil-soluble, etc.). Oxidative stability is a critical property enabling oils to resist sludge formation and degradation while in service.
