Chevron Phillips Chemical offers two lines of PAOs. Two major types of synthetic basestockspolyalkylene glycols (PAG) and polyalphaolefin (PAO)and the lubricants formulated from them, will be compared. 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. In addition to the low temperature performance demonstrated by CCS, the volatility and viscosity index of the PAO 5 and 7 blend are improved over traditional PAO 6. C12-derived PAOs also provide advantages with higher Viscosity Index (VI), better flash/fire points, and even lower cold crank simulated viscosities. 0000000724 00000 n One application in which they have not worked well is in high-temperature (high-pressure) reciprocating air compressors where valve deposits have been an issue. The chart below shows rotary bomb (ASTM D2272) results between Synfluid PAOs and some mineral oils. This is a far greater benefit than can be achieved from other base oils. The dodecene-based products offer lower volatility at comparable viscosities to the decene-based products. NLGI #2. The table below shows how our new Synfluid mPAOs offer significant advantages in pour point and viscosity index over conventional high-viscosity PAOs.
