Rubitherm doesn't mention kinematic viscosity of RT's, neither do they know it.
The following information may be useful for your research
Table 3.1 Thermo-physical properties of RT 21 (Manufacturer’ data)
Property Value
Thermal conductivity 0.2 W m-1 K-1
Melting range 18–23 °C
Freezing range 22–19 °C
Solid density (at 15 °C) 880 kg m-3
Liquid density (at 25 °C) 770 kg m-3
Flash point 154 °C
Kinematic viscosity (at 50 °C) 25.71 mm2 s -1
Heat storage capacity (15–30 °C) 134 kJ kg

they dont mention it in new data sheet.
Thanks a lot prof Krishna, again you were very helpful.
Kind regards,

Hello,
i
n our laboratory we can measure the temperatur and in some cases pressure dependency of viscosity, density, thermal conductivity, heat capacity and melting properties. Make a request! We already measure the thermal behavior of RT 6 and RT 7 and are specialist in measuring those properties.
Kind Regards
Steffen.
