A solution, developed by Renewable Lubricants Inc. (RLI) with assistance from Chevron Phillips Chemical, is the use of Synfluid PAOs combined with biobased oils and specially designed additives. Polyolefins, including poly (ethylene), poly (-olefin), poly (styrene), and poly (dienes), are the most widely-used polymer materials. The chart differentiates the blending capabilities of various base oils to meet energy-efficient motor oils. endobj As fluids flow throughout the equipment, they travel through various lubrication regimes and shear environments, resulting in viscosity changes for non-Newtonian fluids. Disadvantages of PAG-based lubricants are summarized in Table 3. Furthermore, we are able to achieve these properties with non-decene alpha olefin feedstocks while providing advantages over existing products and extending feedstock supply. Whether for automotive or industrial applications, these products can improve performance and solve problems. Typically, as the viscosity drops, the volatility increases. Compatible with seals and paint used with mineral oil, no need for change at all operating temperatures. Using the same PAO, we achieved 15 percent higher oxidative stability by increasing the A.O. Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants. High-viscosity PAO fluids have also become popular in industrial fluids and greases. This lowers their volatility, creates less hydrocarbon tailpipe emissions and raises the flash point. Reducing the viscosity of engine and drivetrain oils lowers fuel consumption by decreased churning losses and viscous drag. There are multiple formulations behind the science of synthetic lubricants that can complicate making the right choice for any application. Rotary screw compressor oils formulated with PAO offer performance benefits not obtainable with a mineral-oil-based formulation. Blending lower-quality base oils into this formulation would compromise the passing mark. Heavier components adversely affect low-temperature performance and pour point. 0
Additives will increase the overall viscosities; however, PAO base oil leaves plenty of room for meeting specifications. Each lubricant type will be the best choice for different sets of use parameters, including: PAO-based lubricants may be preferred when the following lubricant attributes are targeted: PAG-based lubricants may be preferred when the following lubricant attributes are targeted: If end-users are in doubt about which lubricant would best suit their needs, it is recommended that an expert be contacted to assist with the decision-making process. Lack of mineral oil solubility is a barrier to expanded use of PAG-based lubricants. Not necessarily. Specific heat is the amount of heat per unit mass required to raise the temperature one degree Celsius. endobj Chevron Phillips Chemicals proprietary manufacturing process and monomer selection combine to produce the groundbreaking performance characteristics that our customers expect from Synfluid polyalphaolefins. 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. The ability of a lubricant to reach critical metal-to-metal interfaces in a gear system can be the difference between operation or shutdown.
