Key result

Temp.:

other: 25.0°C

Parameter:

kinematic viscosity (in mm²/s)

Value:

ca. 11 130

The kinematic viscosity is calculated by multiplying the efflux time by the viscometer constant. dynamic viscosity (cP) = kinematic viscosity (cSt) × density (g/cm3)

Conclusions:

The kinematic viscosity of Benzene, tetrapropylene-, distn. residues, sulfonated, sodium salts is 11130.0 mm2/s (cST) at 25C.
