C Moderate effectFair D Severe effectNot recommended FOOTNOTES 1. <> Polyalkylene glycol (PAG) and polyalphaolefin (PAO) are two synthetic lubricant options for industrial applications. endobj Approximately 80% of synthetic lubricants used in the world are of three types. Since PAO fluids are synthetic hydrocarbons, they are compatible with and often combined with mineral-based oils. The reason a PAO is selected as a lubricant basestock is its ability to improve performance and solve problems. PAO- and PAG-based lubricants are both hydrolytically stable and have low pour points. Refined mineral oils often contain sulfurs, aromatics and other compounds that can erode the quality and consistency of a mineral oil. There are emerging markets that demand the improved VI and volatility that only the C12-based PAOs can deliver. 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. Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants.

Whether its transportation or industrial lubes, greater fuel efficiency means lower operating costs. Typically, petroleum-base oils are not synonymous with terms like green or environmentally friendly. Note the differences between a VHVI mineral oil and Synfluid Polyalphaolefin (PAO) 5 in the Scanning Brookfield chart below. Compatibility testing is generally carried out at high temperatures, simulating an accelerated life and poor or stressful conditions for the plastic and elastomer/rubber. As temperature increases, a higher VI fluid will give increased fluid film thickness, which could result in lower wear. This is especially true when you consider the entire operating temperature range including startup. Lower-viscosity PAOs have a unique property of biodegradability. 0000000724 00000 n They're found in everyday food and available as supplements. Blending lower-quality base oils into this formulation would compromise the passing mark. From left-to-right, Ken Hope, General PAO Technical Services Manager; EngSoon Ho, Asia PAO Sales Manager; Emanuele Quattrone, EMEA PAO Sales Manager; Katie Clark, Americas PAO Sales Manager. Additionally, PAOs have high viscosity indices, which lead to less film thickness reduction at elevated temperatures. <>>> application/pdf After the formation of the Chevron Phillips Chemical joint venture in 2000, a 10 KTA PAO unit expansion followed soon thereafter. Polyalphaolefins offer great high temperature properties and low volatility. 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. However, nothing is perfect, and polyalphaolefin base oils do have a few negative characteristics. Chemical Compatibility Chart (cont.) 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. 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. Galvanized steel is susceptible to attack by some chemicals which may cause . Polyalphaolefin (PAO) is manufactured through a synthetic chemical process that originates from ethylene. 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. California Transparency in Supply Chains Act Disclosure. 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. Their polymerization can benefit greatly from the development of highly active and highly selective catalysts, as the catalysts strongly affect their properties. Polyalphaolefins (PAO)-60 to 125 C Stable, lubricious fluids compatible with most plastics and elastomers. Both lubricant types are used in industrial gearboxes, compressors, and even air conditioning systems. 0000103071 00000 n We offer a wide range of solutions essential to your products. When unsure of a components precise identity or version, the manufacturer Since we use essentially pure 1-decene or 1-dodecene to produce Synfluid PAOs, there is a narrow isomeric distribution for each oligomer. First, dont touch the gear box; you will burn your hand. 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. A process enhancement at Chevron Phillips Chemicals manufacturing facility has resulted in up to a 30 percent improvement in oxidative stability when used with aminic antioxidants in Rotary Bomb Oxidation Tests (RBOT). This property coupled with excellent oxidative stability provides a formidable component in an engine oil formulators toolbox. Lack of mineral oil solubility is a barrier to expanded use of PAG-based lubricants. C12-derived PAOs also provide advantages with higher Viscosity Index (VI), better flash/fire points, and even lower cold crank simulated viscosities. As pressure increases, so too does the viscosity of the lubricant.
