Abstract
Disclosed is an evacuated and unevacuated microcellular foam containing an infrared attenuating agent (IAA). The evacuated foam has an average cell size of about 70 micrometers or less. The unevacuated foam has an average cell size of 1.0 micrometers or less. The IAA provide a greater proportional reduction in foam thermal conductivity in these foams than in foams of larger cell size. Further disclosed is a method of using the foams.
