Polyalphaolefin does not contain ring structures, double bonds, sulphur, nitrogen components or waxy hydrocarbons. 184 0 obj In addition to these properties, weve also seen a significant reduction in the traction coefficient as compared to conventional high-viscosity PAOs. Oxidative stability is a critical property enabling oils to resist sludge formation and degradation while in service. Chevron Phillips Chemical has been producing two families of PAOs for close to 25 years. These units provide a flow of temperature controlled fluid or Polyalphaolefin liquid. Meet new original equipment manufacturer and industry standard requirements. The chart below illustrates the relative effect base oils have on the operating temperatures in a modified four-ball machine. %PDF-1.4 % 0000010623 00000 n Synthetic basestocks, more so than in mineral oil basestocks, are the primary contributor to most of the basic properties of the lubricant, including oil or water solubility, low-temperature fluidity, lubrication, volatility, ignitability, and seal and paint compatibility. There are indeed pressures in the industry that require improved oxidative stability. The trend falls short when comparisons are made between PAOs and mineral oils, based solely on the VI. 2014-03-26T09:12:59.004-05:00 All rights reserved. %%EOF The rotary bomb bench test is a strong predictor of how base oils will perform in many automotive and industrial applications. With todays oils requiring a higher-quality lubricant basestock to meet more stringent tests, polyalphaolefins are perfectly tailored and consistently manufactured to meet the challenge. These advantages show that PAOs address problems other fluids cannot. 3.0 CHEMICAL COMPATIBILITY GUIDE FOR METALLIC MATERIALS In addition to this chemical compatibility chart, report TR-60C, Bal Seal has two other reports: report TR-60A "Chemical Compatibility Guide for Bal Seal PTFE, Filled PTFE, and Polyethylene Seal Now that fuel economy is more important than ever, even a one percent improvement can make a significant difference on overall costs. hak1YmPaZI>BYzW+d~2^!dVQ ," #@^Ht 9@}VNJ ,kmLrVT U$^H-1' fMH]T U #5o=EmWae4/nW7fg9on_~mSPI_L7borVsezS[uWdg[]]>oo.o7t|xsMU/ojy4i_[u;cJ~Oz5wj1S5"b!CBd2$U3@Rb'EsHd*DzHWcucC=d8tl=d8,trSdx}=dXY>BR>!GB=dph\Wg0?0. endobj Volatility is a concern for many applications, especially where higher operating temperatures occur or longer service life is desired.

Ethylene glycol dimethacrylate is the enoate ester that is the 1,2-bis (methacryloyl) derivative of ethylene glycol. They are usually derived from a small set of simple olefins ( alkenes ). While pour point is one consideration, a formulator has to take into account the total specification needs. Adobe PDF Library 10.0.1 There are multiple considerations when determining the best synthetic lubricant for a particular application, but knowledge of the general properties of the synthetic lubricant types being considered is the starting point. The dodecene-based products offer lower volatility at comparable viscosities to the decene-based products. The information listed in parentheses is D-1418 nomencalture, common acronyms or common trade names. The chart below shows the gas chromatogram of PAO versus white mineral oil, illustrating the relative enhanced purity of PAO. Not Available - Chemical compatibility information is not available at this time. PAO-based greases are typically used at temperatures over 100C because of thermal and oxidative concerns. In a comparison of gear lubricants, PAOs reduced the effective operating temperature by as much as 10 20C. The higher the coefficient, the greater the change in viscosity at elevated pressures. In contrast, the Synfluid PAO formulation achieves a pass with as little as 30 percent PAO, the balance being Group I mineral oil. The ability of a lubricant to reach critical metal-to-metal interfaces in a gear system can be the difference between operation or shutdown. Base Oil Compatibility Chart Base Oil . 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 chart compares two different formulations, one with PAO and another with Group III mineral oils The End of Test viscosity increase left very little room for error in the Group III formulation. The chart below shows specific properties of four of our PAO grades that are well-suited to metalworking applications. For other applications, PAOs safe and non-toxic nature allows them to be used where incidental food contact certification or kosher approval is necessary. When PAO 5 and PAO 7 are compared to equiviscous blends of other PAOs, the volatility advantage can be seen more clearly. PAOs are Newtonian fluids; in other words, their viscosities are fairly independent of shear rate. The challenge presented to a formulator is maintaining the performance levels while achieving biodegradability.
