CPI -1507-150 is a polyalkylene glycol lubricant, formulated to give negligible solubility or dilution in contact with hydrocarbon liquids or vapors. The ability of this lubricant is to withstand dilution by hydrocarbon gases is particularly advantageous in liquid ring vacuum pump and centrifugal compressors handling high concentrations of hydrocarbon and gasoline vapors. CPI-1507-150 is a heat-stable polymer in the absence of oxygen. It is soluble in water. Test Procedure CPI-1507-150 Viscosity @ 40C, cSt, ASTM D445 115.1 Viscosity @ 100C, cSt 17.61 Viscosity @ 100F, SUS 587 Viscosity @ 210F, SUS 90.5 Viscosity Index, ASTM D2270 159 Density, lb/gal, 60F, ASTM D4052 9.27 Pour Point F (C), ASTM D97 22 (-5.6) Flash Point, C.O.C., F (C), ASTM D92 495 (257) Fire Point, C.O.C., F (C), ASTM D92 540 (282) Specific Gravity, ASTM D4052 1.11 These are typical values and are not intended for use in preparing specifications.
