Were here to help. In the past three years, European specifications for volatility and oxidative stability have become significantly more stringent. Dominant in a commercial sense are polyethylene and polypropylene. The lower volatility decreases oil replacement costs by reducing oil consumption. One obvious trend is that low-viscosity oils are beneficial in improving fuel efficiency. Blending lower-quality base oils into this formulation would compromise the passing mark. In addition to the low temperature performance demonstrated by CCS, the volatility and viscosity index of the PAO 5 and 7 blend are improved over traditional PAO 6. Certainly! PDF Synthetic Oil Viscosity & Compatibility Chart - DULUB 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. 0000001764 00000 n They have different characteristics, meaning that one may be superior to the other under certain circumstances. Furthermore, these new formulations allow a range of ISO viscosity grades. As pressure increases, so too does the viscosity of the lubricant. Now that fuel economy is more important than ever, even a one percent improvement can make a significant difference on overall costs. Therefore, reducing the temperature is generally beneficial in extending the life of a lubricant. General properties of water-soluble, water-insoluble, and oil-soluble PAG basestocks are shown in Table 1. Our customers quickly realized the advantages in volatility, low-temperature viscometrics, VI and flash and fire points in equiviscous blends compared to 1-decene-based materials. I love to talk about food, and I love to talk about Synfluid PAO! Chevron Phillips Chemicals PAO history dates back to December 1980, when the continuous PAO unit at Cedar Bayou, Texas, started up with heritage Gulf Oil, which Chevron Chemical subsequently acquired in 1985. The relative availability of olefin monomer was certainly a consideration (i.e., 1-octene vs. 1-decene). While viscosity improvers can enhance VI, they can break down over time, resulting in diminished performance. All rights reserved. The chart compares two different formulations, one with PAO and another with Group III mineral oils The End of Test viscosity increase left very little room for error in the Group III formulation. To correctly identify what type of fluid is needed, the end-user must know the minimum lubricant requirements for that piece of equipment. This is just one of the many performance advantages of Synfluid mPAO. John Sherman is Shell Project Lead PAG Lubricant Technology, Industrial Oils and Tech Services; Robert Profilet is Technology Manager, Industrial Lubricants; Warren Cates is Shell Senior Researcher, Industrial Oils and Tech Services; Iris Song is Shell Engineer, Industrial Oils and Tech Services; and Sameer Sathaye is Shell Project Leader Industrial Oils, Industrial Oils and Tech Services. <>>> Although VI is an important indicator, when used alone, VI is misleading. Compatibility for Base Oil Families Soluble in large fraction Weakly soluble Insoluble Varies with grade Solvent Compatibility for Base Oil Families Note 1: For cross reference to trade names, consult Modern Plastics Encyclopedia, '97, McGraw-Hill Company, New York, 1997. 0000052609 00000 n PAG- and PAO-based lubricants are used in multiple industries and, as synthetics, offer improved performance over mineral oils. Benefits of the new system are a much higher viscosity index (VI), superior pour points and improved low-temperature fluidity, all of which contribute to improved energy efficiency. The chart below shows the trends in industry specifications regarding low-temperature performance relative to Synfluid PAO.
