Thermal conductlviJ, and Its related property thermal difiusity, 1s a most Important iunctlonal pararrieter In the appllcatlon and use of cellular plastics. The ma}or avallable methods to rrieasure the thermal conductivity of different types and forms of cellular polymers are presented and discussed. Results are presented to llkisirate the Influence of various parameters Including tempera- ture, environment, agelng, specimen slze and form and are died with partlcuiar respect to apphcations of these materlal.
