Adobe InDesign CS6 (Macintosh) D = Severe Effect, not recommended for ANY use. One reason for moving to low-viscosity oils is to focus on initial and long-term fuel economy. Oxidative and other lubricant degradation mechanisms would follow the same trend. PAO fluids are classified as a Group IV base oil and are made by a two-step reaction process using linear alpha-olefins like 1-decene. One example is the advantage PAO has over mineral oil in the area of high-temperature stability. Because PAOs have a diverse, highly branched isoparaffin structure, they provide excellent low-temperature viscometrics and very low pour points (ppt) without adding PPDs. Chemical Compatibility Guide 0000014966 00000 n Chemical Compatibility Guide The higher the coefficient, the greater the change in viscosity at elevated pressures. Approximately 80% of synthetic lubricants used in the world are of three types. This lowers their volatility, creates less hydrocarbon tailpipe emissions and raises the flash point. Polyalphaolefin is by far the most common major synthetic base oil used in industrial and automotive lubricants. This chart illustrates another benefit of using Synfluid PAOs at increased antioxidant treat rates. PAG- and PAO-based lubricants rarely compete in industrial applications. Give us a call, and well be glad to discuss your applications and provide technical help.

The tests used below were the Cold Cranking Simulator for high shear (about 10-1 sec-1) and Brookfield viscosity for low shear (about 2 sec-1) each measured at -20C. The vast number of high-quality base oil choices can be daunting when trying to balance fuel efficiency and wear protection. These include PAOs and also relatively common polyisobutenes (PIB), which are sometimes used as oil additives or as base oils in two-stroke engines. The term synthetic hydrocarbon (SHC) is a general term. Give us a call. These combined benefits provide the properties required for severe service applications and extended drain intervals. Typically, as the viscosity drops, the volatility increases. Great question! Polyalphaolefin (PAO) fluids are the most common major synthetic base oil used in industrial and automotive lubricants. Some of the advantages of PAO-based lubricants are summarized in Table 5. Were a company with deep-rooted values, and were looking for people like you to join our team. Later used in many industrial applications from compressor, hydraulic, and turbine fluids to gear oils and metalworking fluids. Rotary screw compressor oils formulated with PAO offer performance benefits not obtainable with a mineral-oil-based formulation.

A run through the test: 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. Defense Daily subscriber and registered users, please log in here to access the content. The chart below shows pressure coefficient comparisons between PAOs and Group III mineral oils versus pressure: Gear systems are specially designed and require highly specialized lubricants. 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). 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. 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. As oil volatilizes, the viscosity increase will result in poorer overall performance. Reducing the viscosity of engine and drivetrain oils lowers fuel consumption by decreased churning losses and viscous drag. I love to talk about food, and I love to talk about Synfluid PAO! The more EO monomer in the basestock, the more water-soluble; the more PO monomer, the more water-insoluble; and the more BO monomer, the more oil-soluble the basestock is. 91 0 obj These advantages are achieved without the need for VI improvers or other additives, which may promote other deleterious effects as they degrade. 0000140193 00000 n Kinematic Viscosity @ 100C (cSt) Kinematic Viscosity @ 40C (cSt) Pour Point (F) Molecular Weight. 0000002226 00000 n This is just one of the many performance advantages of Synfluid mPAO. 0000035336 00000 n <>>> 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).

The lighter components cause poorer volatility properties as well as lower flash and fire points. Some claim the Viscosity Index (VI) is the overriding parameter used when choosing a base oil. This resistance to fire and flame propagation improves the margin of safety in the event of a hydraulic leak. PAG-based lubricants are polar (water-soluble PAG > water-insoluble PAG > oil-soluble PAG), where PAO-based lubricants are essentially non-polar. Oils made with PAOs demonstrate an inherently high viscosity index and maintain excellent low-temperature performance, compared with mineral oils. Thats a hot topic! Address new equipment conditions (higher operating temperature and pressure, greater loads and speed). The PAOs . The qualitative chart below describes the impact of each grease component on certain performance characteristics: Clearly, the base oil dominates some grease properties, while the additives or thickener drives others.
