Compatibility testing is generally carried out at high temperatures, simulating an accelerated life and poor or stressful conditions for the plastic and elastomer/rubber. Poly-Alpha-Olefins - an overview | ScienceDirect Topics Remember, PAOs are carefully designed, not refined. Two major types of synthetic basestockspolyalkylene glycols (PAG) and polyalphaolefin (PAO)and the lubricants formulated from them, will be compared.

The chart below shows the effect of two different shear rate viscosity determinations on three different fluids (4 cSt at 100C) and the dramatic differences between them. While pour point is one consideration, a formulator has to take into account the total specification needs. PAG-based lubricants are polar (water-soluble PAG > water-insoluble PAG > oil-soluble PAG), where PAO-based lubricants are essentially non-polar. Challenges like these truly reveal the performance advantages of Synfluid PAOs. The superior low-temperature flow characteristics of PAOs ensure faster coating of critical parts in the compressor during startup, minimizing wear. Certainly! Chemical Compatibility Guide; what chemicals to use; guide for chemical uses; general guideline for pump material selection; material chemical compatibility PAO-base oils help improve fuel economy in engine and drivetrain oils by reducing viscosity, volatility and traction coefficients as the chart below shows: These results show the potential for reducing friction loss using PAOs, which also typically have lower pressure-viscosity coefficients than mineral oils reducing elastohydrodynamic gear friction losses and energy consumption. As oil volatilizes, the viscosity increase will result in poorer overall performance. A formulator choosing the right base oil is like a craftsman choosing the right tool it needs to fit the job. polyalphaolefin compatibility chart. 2013-07-10T14:05:23-05:00 Low-viscosity PAO fluids are used in automotive applications, such as engine oil and gear lubricants. When you compound this with difficult operating conditions, such as extreme temperatures, high loads or extended operations, a high-quality base oil may be necessary. This is one clear benefit of using a carefully designed base oil. Better heat transfer coefficients, increased lubricity and the basic chemical structure of PAOs all contribute to the lower temperature in the gearbox. xref For instance, boosting the additive package with an additional 0.4% aminic antioxidant, in combination with the Synfluid PAO base oil, achieved a 35 percent improvement in HPDSC results. If a polyurea-based thickener is chosen in conjunction with a synthetic base oil, such as a polyalphaolefin (PAO), there is no compatibility risk to be expected. In order of volume used, they are: polyalphaolefins (PAOs), organic esters, and polyglycols. Refined mineral oils often contain sulfurs, aromatics and other compounds that can erode the quality and consistency of a mineral oil. 0000000416 00000 n Due to constraints with the supply of 1-decene, the traditional feedstock for PAOs, producers have experimented with alternative feedstocks to meet demand.

The current trend toward lower viscosities, while providing for extended drain capabilities, does present an interesting challenge for base oils. Low-temperature fluidity and high-temperature thermal and oxidative stability are key factors for choosing a PAO. Polyalkylene glycol (PAG) and polyalphaolefin (PAO) are two synthetic lubricant options for industrial applications. Synfluid PAOs also have a very high degree of saturation, which in lubricants provides oxidative stability. 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. Consistent feedstocks give rise to consistent PAO quality, resulting in consistent finished fluid performance.

Therefore, at high temperatures, it is advantageous to utilize a more stable base oil, specifically Synfluid PAO. 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. A product developed by Renewable Lubricants Inc. (RLI), with assistance from Chevron Phillips Chemical, uses Synfluid PAOs combined with biobased oils and specially designed additives. Temp.
