In this section, HFC, HCFC, HC, and methylal are generally called physical blowing agents.
The potential use of methylal as a co-blowing agent with 245fa seems unsuitable, as it has a higher effective diffusion coefficient.
Moreover, in the presence of methylal or n-pentane the initial value is somewhat higher, probably due to the higher vapor phase thermal conductivity rather than for the mean cell dimension; in fact, n-pentane blown foam shows lower mean cell diameter but higher initial thermal conductivity.
