Compatibility testing is generally carried out at high temperatures, simulating an accelerated life and poor or stressful conditions for the plastic and elastomer/rubber. xref 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. The lighter components cause poorer volatility properties as well as lower flash and fire points. 101 0 obj ]-]jW|^X^=E^7J3kgI%_9+v}Fwq{r9 *d(C>~z|7X#o!9lwu{^1se9),7v)mE,wa?t3 a$X{wzVAw}E^:5--_OXY+. <> Technical White Oils are approved for incidental food contact at USDA-approved meat and poultry plants. Several synthetic base oil types fall into the SHC category. Note the differences between a VHVI mineral oil and Synfluid Polyalphaolefin (PAO) 5 in the Scanning Brookfield chart below. Our Synfluid mPAO is based on a single monomer, AlphaPlus 1-Octene. PAOs help to balance the protection and energy conservation requirements in equipment because they are more Newtonian than mineral oils. Consistent feedstocks give rise to consistent PAO quality, resulting in consistent finished fluid performance. Remember, PAOs are carefully designed, not refined. Understanding the advantages and disadvantages of each can help end-users decide which option is best for a given application. One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. CHEMICAL RESISTANCE CHART. Dominant in a commercial sense are polyethylene and polypropylene. However, Group III base stocks are derived from multiple feedstock choices and processing technologies, which create variability in the properties. 0000012542 00000 n Process Chemical Compatibility Guide We are first in your inbox with the most important news in the industry―keeping you smarter and one-step ahead in this ever-changing and competitive market.

Finally, due to their excellent response to antioxidants, Spectra-Syn Plus PAO can be formulated to resist thermal oxidative attack. The magnitude of these benefits will depend on the particular formulation. If you are using multiple greases, there are certain risks for misapplication, which are minimized with a multi-purpose grease. %PDF-1.5 % Three stringent test standards required by Volkswagen and Mercedes-Benz engines show the impact of the variability of Group III oils: This data illustrates lot-to-lot variability, which has been recognized for the Group III oils. These include PAOs and also relatively common polyisobutenes (PIB), which are sometimes used as oil additives or as base oils in two-stroke engines. To improve fuel economy, OEMs are moving toward lower-viscosity oils, even in heavy-duty diesel engines. In a comparison of gear lubricants, PAOs reduced the effective operating temperature by as much as 10 20C. The dodecene-based products offer lower volatility at comparable viscosities to the decene-based products. We expect that specifications for driveline fluids will continue to tighten due to pressure from energy conservation, improved transmission design and fluid longevity. <> polyalphaolefin compatibility chart. As a result, the jump in the viscosity adversely effects the ability to pump at low temperatures. You would expect the viscosity to improve with a lower pour point, but the opposite is true. MOLYKOTE. Youre not kidding! 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. Not necessarily. Give us a call. startxref What is most interesting, however, is the low-temperature performance: The C10-based PAO 6 has the lowest pour point by over 20C, but the CCS viscosity for the C12-based PAO 5 and 7 blend is better. From then on, the company introduced 1-dodecene-based PAOs in 1995, which have grown steadily in popularity. PAOs are Newtonian fluids; in other words, their viscosities are fairly independent of shear rate. Approximately 80% of synthetic lubricants used in the world are of three types. The Scanning Brookfield chart on this page demonstrates the difference in viscometrics between a Synfluid PAO and a pour point depressed mineral oil. 0000001332 00000 n PAOs are considered a very pure substance since they are derived from petrochemically pure ethylene and then from 1-decene or 1-dodecene, which could be considered a further purification step.
