摘要：

The gaseous thermal conductivities of 15 new hydrofluoroethers (HFEs) were measured by a steady state coaxial cylinder method. The results were compared with those obtained separately by a transient hot-wire method. Deviations between the two methods are less than 3.4%. In comparison with hydrofluorocarbons (HFCs), cyclopentane and CO2, it was found that the HFEs investigated show lower thermal conductivities than other promising candidates for the traditional blowing agents for polyurethane foams.
