Vapor pressure and saturated liquid density for HFE7100 were measured in the temperature range from 300 K to 400 K at intervals of 10 K by using the extraction method. Experimental uncertainties are estimated to be 0.028 K for temperature, 0.4 kPa for pressure and 0.8 kg/m^3 for density. Vapor pressure is obtained in the pressure range from 28 kPa to 629 kPa. Saturated liquid density is obtained in the pressure range from 1203 kg/m^3 to 1516 kg/m^3. On a basis of the present data, correlations of vapor pressure and saturated liquid density were formulated using fourth-order polynomial equation. The maximum deviations from correlations were 1.1 kPa for vapor pressure and 1.2 kg/m^3 for saturated liquid density, respectively. The standard deviations from correlations were 0.6 kPa for vapor pressure and 0.4 kg/m^3 for saturated liquid density, respectively.
