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.
