• Densities of R32+R1234ze(E) mixtures were measured with a vibrating-tube densimeter.
• Densities of mixtures were conducted from (283 to 363) K, at pressures up to 100 MPa.
• Excess molar volumes were correlated with the Redlich–Kister equation.
Values of experimental density of difluoromethane (R32) and five compositions of {R32 + trans-1,3,3,3-tetrafluoropropene (R1234ze(E))} binary mixtures are reported over the temperature range from 283 K to 363 K and at pressures up to 100 MPa with a vibrating-tube densimeter. The excess molar volumes were calculated from experimental results and fitted to the Redlich–Kister equation. The maximum standard deviation and average standard deviations of the experimental and calculated values of excess molar volume from Redlich–Kister equation are 0.07789 cm3·mol−1 and 0.01645 cm3·mol−1, respectively.
