Furthermore, thermal conductivity at 300F for PAO 6 is 0.085 compared to 0.071 Btuft/(hft2F) for an equiviscous mineral oil, which means that the PAO can conduct 20percent more heat than the mineral oil for better heat dissipation. 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. Low molecular weight compounds will degrade other performance requirements, such as volatility, flash and fire points. The uniquely beneficial quality of PAOs has been demonstrated in a series of European engine tests. Naval Research Laboratory (USNRL) was begun to develop hydraulic fluids that would be more fire-resistant than the ones used at the time based on mineral oil. The superior benefits of PAOs enable formulators to meet these challenges. 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. 0000034289 00000 n This is a recurring situation and is what led to the development of 1-dodecene based Synfluid PAOs in 1995.

One key advantage PAOs have over mineral oils is a greater ability to dissipate heat. 0000161810 00000 n There are other advantages, such as oxidative and thermal stability, which you would naturally expect from a PAO-based product. Whichever low-viscosity base oil is used, it must exhibit viscosity stability and low volatility. Due to constraints with the supply of 1-decene, the traditional feedstock for PAOs, producers have experimented with alternative feedstocks to meet demand. As temperature increases, a higher VI fluid will give increased fluid film thickness, which could result in lower wear. As a result, the jump in the viscosity adversely effects the ability to pump at low temperatures. This process creates a polymer backbone where oxygen is every third atom, which gives PAG basestocks their distinctive chemical attributes and allows formulators to synthesize various combinations of starters and monomers (block, random, and homopolymer) to create custom basestock types for specific applications. We believe it can be understood by looking at the thermal conductivity and specific heat of the base oils. The chart below shows rotary bomb (ASTM D2272) results between Synfluid PAOs and some mineral oils. This provides several advantages, one of which can be illustrated by gas chromatography.
