Image Analysis and the Characterization of Cellular Plastics

An evaluation of sprayed polyurethane foams manufactured with alternative blowing agents is being performed under a joint research program be tween the Society of the Plastics Industry of Canada and the Institute for Research in Construction. Image analysis, or the computer-aided quantification of the cell structure of the foams is a part of this evaluation. Samples of foams prepared using the same polymer with different blowing agents were …
