ABSTRACT:
Disclosed is a method of insulating a surface or enclosure by applying to the surface or enclosure a polymeric foam structure of a polymer material and carbon black. The carbon black is generally uniformly dispersed in the polymer matrix in the form of discrete particles substantially free of agglomeration. A preferred carbon black is thermal black. The carbon black provides a number of advantages over those previously employed commercially. Further disclosed is a process for making the foam structure. Further disclosed is an extruded, insulative foam structure of the type described above.
