3M™ Fluorinert™ Electronic Liquids are part of a family of fully-fluorinated compounds known as perfluorocarbons, or PFCs. For more than forty years, Fluorinert liquids have been used as heat transfer media for direct contact cooling, automated testing, reflow soldering, etching, CVD and more.      (All values determined at 25˚C unless otherwise specified)   FC-87 FC-72 FC-84 FC-770 FC-3255 FC-3283 FC-40 FC-43 FC-70 Bolling Point(℃) 30 56 80 95 103 128 155 174 215 Pour Point (℃) -115 -90 -95 -127 -30 -50 -57 -50 -25 Vapor Pressure (Pa) 81.1x10³ 30.9x10³ 10.6x10³ 6.56x10³ 4.15x10³ 1.44x10³ 432 192 15 Density (kg/㎥) 1650 1680 1730 1793 1770 1820 1850 1860 1940 Coefficlent of Volume Expansion(℃-¹) 0.0015 0.0016 0.0015 0.0014 0.0014 0.0014 0.0012 0.0012 0.0010 Kinematic viscosity (cSt) 0.28 0.38 0.53 0.79 0.71 0.75 1.8 2.5 12 Absolute Viscosity (centipoise) 0.45 0.64 0.91 1.35 1.4 1.4 3.4 4.7 24 Specific Heat (J kg-¹ ℃-¹) 1100 1100 1100 1100 1100 1100 1100 1100 1100 Heat of Vaporization @ B.P.
